    The Leather Knife Roll Designed by a Chef
    You can tell a lot about a chef from their knife roll. Unfortunately, from what we hear often, finding a high quality knife roll to protect chefs’ knives doesn’t seem like such an easy task. That’s probably why this beautiful leather knife roll has got so many chefs excited.
    Called the “perfect storage tool” by Food & Wine, the beautiful piece of kit is part of a collaboration between an award-winning chef, an artisan blacksmith and some outdoor gear craftsmen.

    “Durability, balance and comfort” were the three key attributes that chef Chris Hastings (Hot and Hot Fish Club and OvenBird) looked to incorporate in the leather knife roll, and working together with Radcliffe Menge, the founder of Tom Beckbe, Alabama-based outdoor apparel company, they came up with the perfect piece of gear for professional chefs.

    It comes in a full-grain vegetable tanned leather that is durable and elegant, and it is functional with space for 18 knives and eight additional pieces of hardware. Adjustable shoulder straps make this high quality roll bag comfortable and ergonomic.
    The key feature of the knife roll is that it is balanced – knives are placed on both sides so the blades cross over one another in opposing pockets. A three-part interior flap system and two exterior belts make sure knives are secure.If you want to fill up your new leather knife roll with a set of equally good-looking knives - and have US$2,499 to spare - check out the limited edition chef knives also available on their website. Hastings and Menge teamed up with Will Manning, the blacksmith of Tennessee knife brand Heartwood Forge, who created the set that includes three knives - an elongated paring knife, a traditional chef’s knife and a cleaver-like knife that Menge calls the Butcher’s Haste.

    Most slitter blades feature a beveled edge for optimal cutting power. A beveled edge allows a blade to slit material instead of creating standard cuts. When a slitting knife has the primary purpose of making punctures, it will have teeth. These teeth create smaller slits in progression, such as the ones found on tear-off paper products. Our sales engineers can help you determine which blade solution will work best for your application.

    At York Saw & Knife, we manufacture all of our slitter blades in-house. As an original equipment manufacturer, you’ll appreciate our competitive prices and fast turnaround times that allow you to maximize your profits. If you get our blades as an end-user, we will listen to your needs to design a personalized solution. We consider your business goals our business goals.

    Our slitter blades can slit a wide range of materials, including:

    Paper: A slitting blade can create slits and perforations in paper for a variety of purposes. For example, a toothed slitter blade can create a tear-off line for tear-away paper products.

    Corrugated products: Corrugated products such as fiberboard and cardboard need high-quality blades for the best cutting results. Our expertly made slitting knives can create slits in these materials while keeping their edge.

    Food and meats: Slitting knives can slice and score a variety of food products. We can develop custom blades for applications like meat slicing and processing.

    Foil and film: Our precision slitting blades have the sharpness needed to smoothly slit foil. You can also request a custom blade for slitting other delicate materials like film.

    Textiles: Fabric requires a sturdy blade that retains its edge throughout regular cutting operations. Our team develops custom slitting blades for textiles that achieve the cuts you need.

    Plastics: We can design slitting knives suitable for plastics of various thicknesses and compositions. Their sharpness and durability allow you to work with a wide range of synthetic materials.

    And more

    This list includes just a few of the possible applications for slitting knives. Thanks to our versatile capabilities, you can specify a slitting blade design for a variety of uses.

    Long blade knives
    In this article, we will introduce you to knives that have a blade length of at least 20 centimetres. It is obvious that long blades are particularly well-suited to larger ingre-dients, but these knives excel in different areas too, as you will find out:

    Super Slicer: the cut-anything knife
    There are some ingredients that demand a truly exceptional knife: the tough skin of a pineapple, for example, or the stalk of an artichoke. And the Super Slicer can easily handle both: the convex, outwardly shaped serrations of the blade ensure pow-erful and clean cuts - even with very fibrous, tough foods.
    Salmon knife: sharp and flexible
    Granted, there isn’t always a suitable knife for every possible situation. But, if you have a whole salmon in front of you, or at least half of one, you'll love this blade. The Salmon knife is very long, sharp and flexible, so you don't tear the fine flesh of the fish and you can cut wafer-thin slices.

    Ham knife: also suitable as a carving knife
    Of course we have the right speciality knife in our range when it comes to smaller hams. Thanks to its long, narrow blade, the Ham knife is also suitable as a carving knife, as you can use it to carve up roasts, hams or poultry – whether raw or cooked – very efficiently.

    How to choose the suitable material for cutting knife blade of industrial shredders
    Shredder blade is a kind of cutter that is equipped on industrial shredder or granulator. They are machines for crushing waste materials like rubber, tires, wood, paper, polymers, plastic, textiles and so forth. As we all know, industrial waste shredders are playing a critical role in the recycling industry. For one thing, they can save a lot of storage space. Data indicates a shredder can reduce the total volume of processed industrial waste by 30%-50% on average. For another thing, shredders optimize the value of industrial wastes by forming them into granule reaching a recyclable level.
    As space is limited, we only pay attention to the cutter part of a shredder. Many variables to affect shredder cutter’s efficiency, such as cutting angle, numbers of knives, cutting velocity, chip load, etc. Above all, A primary factor is If the cutter material is suitable to deal with the industrial waste. That’s always the first thing on your concern.
    Materials of shredder cutter out there vary, so do the materials of industrial waste, too.
    Common trash wood includes cardboard, paper, solid wood, and plywood board. For brittle wood, such as branches, twig, cardboard, SK5 is a practical and economical option. The steel is a kind of carbon tool steel with nice resistance to wear, but poor plasticity and hardenability. SK5 is often used to make woodworking knives, and sample-sized dies. Its performance is not super outstanding, which results in its cheaper price, compared with other types of wood-processed steels.
    However, for high-strength trash wood, such as stumps, plywood boards, and discarded furniture, SK5 is not competent. We’d turn to use high manganese steel, accordingly. High manganese steel is generally used to make a smashing hammer in mining and architecture industry. Its metal hardened depth can reach 10mm-20mm and remain as hard as HB500-550. When working at a high torque, the manganese steel will not be easily deformed or even broken like SK5. In addition to this, the high manganese steel is more affordable, compared with other alloy carbon steel.
    2.For shredding plastic
    In the plastic industry collectors and recyclers started their business pretty late compared to areas of scrap wood and paper&cardboard. Trash plastic can be generally a huge blend with at least the same amount of possible additives and fillers. They contain not only lower grade plastic but also high-value ones. Thus we need to recognize which type of plastic is in the input mixture.
    The principle of the crusher blade is to use a set of running knives to smash the target (pulverized material). When the target (pulverized material) is broken by the crusher blade, the blade is gradually worn out.

    There are many applications at different industries which are using crusher knives . Therefore, Jiuli Knives will base on the client's application to select the right material to produce the crusher blade, and it will influence the wear resistance and toughness of the crusher knife to be optimized, the product life of the blade to be increased, the pulverizing ability to be maximized and the thickness of the pulverized powder is uniform.

    The slitter rewinder blades are mainly applied to rewinders for slitting of tissue paper. The quality of rewinder blades directly affect the production quality and efficiency. Seton developed circular tungsten carbide and inlay carbide rewinder blades to improve customers' use effect and blades' service life.

    As for the selection of cutting tool materials, we can make recommendation according to customers' cutting materials, so as to ensure that customers can use the appropriate knives during production. The common specifications of blades may be not suitable for your machines, and if needed, please send us the samples or drawings. We will manufacture strictly in accordance with the design precision.

  • Benefits of CNGDateWed Oct 26, 2022 8:35 am

    Benefits of CNG
    Environmentally Friendly, Reduced maintenance cost, CNG Produces significantly less Pollutants than petrol/diesel, natural gas is cheaper & safer than Petrol/diesel, Green fuel.

    Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions thus reducing the effect of global warming. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated.

    CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees centigrade) and a narrow range (5%-15%) of in flammability. It means that if CNG concentration in the air is below 5% or above 15%, it will not burn. This high ignition temperature and limited flammability range makes accidental ignition or combustion very unlikely.

    Low operational cost:
    The operational cost of vehicles running on CNG, as compared to those running on other fuels, is significantly low. At the prevailing price of fuel in Delhi, Operational cost of CNG vehicles is 66% lower than petrol and 28% lower than diesel.

    Increased life of oils:
    Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil.

    Mixes evenly in air:
    Being a gaseous fuel CNG mixes in the air easily and evenly.

    a) Easy on the pocket.
    b) CNG delivers high performance at low cost, as it gives your vehicle a better mileage.
    c)CNG does not contaminate or dilute crank case oil, giving engine an extended life.

    Eco friendly:
    a) The use of CNG significantly reduces harmful vehicular exhaust gas emissions like carbon dioxide, carbon monoxide and other suspended particles.
    b) It protects the environment by reducing the effects of global warming.
    c) Non –toxic, non-corrosive, non-carcinogenic and hence improves public health.

    Safe &Reliable:
    a) CNG is lighter than air and hence disperses quickly without any dangerous accumulation.
    b) CNG has a narrow flammability range making it much safer than other fuels.
    c) CNG has a higher ignition temperature than other fuels, reducing chances of accidental and spontaneous ignition.

    It matters how the electricity is made
    Broadly speaking, most electric cars sold today tend to produce significantly fewer planet-warming emissions than most cars fueled with gasoline. But a lot depends on how much coal is being burned to charge up those plug-in vehicles. And electric grids still need to get much, much cleaner before electric vehicles are truly emissions free.

    One way to compare the climate impacts of different vehicle models is with this interactive online tool by researchers at the Massachusetts Institute of Technology, who tried to incorporate all the relevant factors: the emissions involved in manufacturing the cars and in producing gasoline and diesel fuel, how much gasoline conventional cars burn, and where the electricity to charge electric vehicles comes from.

    If you assume electric vehicles are drawing their power from the average grid in the United States, which typically includes a mix of fossil fuel and renewable power plants, then they’re almost always much greener than conventional cars. Even though electric vehicles are more emissions-intensive to make because of their batteries, their electric motors are more efficient than traditional internal combustion engines that burn fossil fuels.

    Natural gas vehicles (NGVs) can offer an array of economic and environmental benefits to California residents. These may include the economic benefits of a low-cost, domestic fuel, developing a market for green jobs, improving regional air quality, reducing greenhouse gas emissions, reducing our dependence on petroleum and providing a pathway to a hydrogen economy.

    Environmental Benefits
    Natural gas vehicles can have an immediate and positive impact on the issues of air quality, U.S. energy security and public health. Here are some key benefits of using natural gas as a transportation fuel.

    NGVs are Clean
    NGVs are some of the cleanest vehicles in commercial production today, and produce only 5-10 percent of the emissions allowable, even by today's most stringent standards. NGVs produce 20-30 percent less greenhouse gases than gasoline- or diesel-powered vehicles.

    Overall, natural gas is one of the cleanest burning alternative fuels available today. NGVs can reduce nitrogen oxide (NOx) emissions and reactive hydrocarbons which form ground-level ozone, the principal ingredient of smog, by as much as 95 percent. NGVs can also reduce emissions of carbon dioxide by as much as 30 percent, carbon monoxide (CO) by 85 percent and carcinogenic particulate emissions by 99 percent.

    Reducing Greenhouse Gas Emissions
    The use of compressed natural gas (CNG) in place of gasoline or diesel can help reduce greenhouse gases.

    A 2008 "well to wheels" analysis conducted by TIAX, LLC concludes that natural gas offers up to a 30 percent reduction in greenhouse gas (GHG) emissions for light-duty vehicles, and as much as a 23 percent reduction for medium- to heavy-duty vehicles, when compared with gasoline and diesel. The chart below shows the amount of C02 that has been displaced since 1999 by SoCalGas? customers using vehicles powered by CNG instead of diesel. In 2008 alone, that number was almost 229,000 metric tons of CO2!

    Clearly, NGVs present one of the cleanest choices for today and tomorrow.

    Concept of LNG
    LNG is a natural gas (predominantly methane, CH4) that has been converted to liquid form for ease of storage or transport. After being liquefied, it takes up about 1/600 the volume of natural gas in the gaseous state and about 45% the weight of water in equal volume. As a cleaner energy, natural gas is increasingly favored. LNG is proposed to be the prior choice of alternative fuels in many countries, for example, United States, Canada, Europe, and China. As a result, the ratio of natural gas in energy supply increases rapidly. While compressed natural gas (CNG) is just suitable for light-duty vehicles, LNG can be used in road transport, such as heavy-duty trucks and buses. In China, CNG buses and LNG buses were introduced into the bus fleet in Beijing in 1999 and 2012, respectively. After that, more and more cities in China have swift some diesel buses to LNG buses, for example, Guangzhou, Xiamen, and Shenzhen. Heavy-duty vehicle, whose total mass is 14 tons or more, is the main object of promoting LNG vehicles in Shenzhen road freight. Different from light-duty vehicle using diverse fuel (e.g. gasoline, diesel, CNG, and electric), heavy-duty vehicle uses diesel or LNG because the fuel’s energy density must be high enough to meet its power requirement. There are three main types of LNG heavy-duty vehicles in Shenzhen, namely, container tractors, engineering dump trucks, and engineering mixers.

    LNG supply safety
    The main sources of LNG supplied to Shenzhen include foreign imports and provincial imports. The former is mainly from Australia, Malaysia, and so on. The latter is the Second West-East Gas Pipeline Project, supplying natural gas of about 40?billion m3/year for Shenzhen. Natural gas is transported through pipeline in gaseous state, so it needs complex liquefaction process involving removal of certain components, for example, dust, acid gases, helium, and water. Besides, a small amount of LNG is transported to Shenzhen by cargo transport containers from Inner Mongolia, Xinjiang, and other gas fields. In addition, the contract of Russia’s gas project was signed. A diversity of LNG source markets appear.

    Shenzhen has the largest number and the biggest LNG terminals in China. After all of the terminals have become fully operational, the supply capacity of LNG will greatly exceed 11?million tons/year, accounting for around 55% of that in Guangdong province. Along with picking up LNG at adjacent cities, LNG supply is totally guaranteed.

    LNG fueling stations
    The number of LNG fueling stations is still not enough in Shenzhen. Besides, the layout of LNG fueling stations is unreasonable. China National Offshore Oil Corporation (CNOOC) Shenzhen Gas Co., Ltd is one of the largest automotive LNG suppliers. By the end of 2015, it had built 17 LNG fueling stations distributed at 6 districts, such as Nanshan, Baoan, Longgang, Yantian, Guangming, and Longhua . At present, nine of them have been put into use. Their clients include buses, coaches, container tractors, dump trucks, and engineering mixers. It just takes 3?min to refill a gas tank of LNG vehicle, which is shorter than refilling diesel to a diesel vehicle due to the high pressure of gas dispenser.

    Due to the raising economy development of Shenzhen, environmental problems brought by road transport have become more serious. Promoting liquefied natural gas vehicle in the road freight is a key to reduce emissions, change the direction for road freight development, and build a resource-saving society. This article studies the application of liquefied natural gas vehicle in Shenzhen in-depth through official data sets, field investigation, expert consultation, and so on. Economic benefit analysis shows that liquefied natural gas vehicle has the advantage of saving considerable fuel costs for enterprises. Moreover, the Monte-Carlo method is used to evaluate the economic benefits considering a lot of factors. The economic analysis shows that the liquefied natural gas vehicle is more affordable than the diesel vehicle. Finally, the current issues of liquefied natural gas vehicles on the promotion are discussed and some advices are proposed to improve air quality and reduce emissions.
