Caribou Media Group earns a commission from qualifying purchases. 154CM: X15-TN: Press J to jump to the feed. “The powder is applied with an electrostatic spray gun. While these other finishes are OK, PVD coating cannot chip or rub off because it’s bonded to the steel at a molecular level.”. It offers excellent corrosion resistance as a blade material. Before the powder is sent to the gun, it is fluidized to separate the individual grains of powder and improve the electrostatic charge that can be applied to the powder so that the powder flows more easily to the gun. See one of our clip-point blades here! I've wondered how bluing might work.  A stainless steel comparable to 440C in performance and value. Iseya. Alright. N690: Delrin: 8Cr13CoMov: “To obtain the final solid, tough, abrasion-resistant coating, the powder-coated items are placed in an oven and heated to temperatures that range from 160 to 210 degrees Celsius, depending on the powder—400 degrees in our case.”.  Built from the framework of a locking liner; the lock engages using tensile strength compared to the compression hold of more traditional locking-liners. M390 is a popular steel for use in surgical instruments and other applications that require a high finish. Probably not food safe.  Like the AXIS® mechanism, this requires the user to propel the blade at least partially out of the knife handle. Carbon fiber handles offer exceptional strength while adding almost no additional weight to the knife itself.  This steel has excellent corrosion resistance properties, especially to salt water. advertisementvar RevContentSolo = { button_text: 'Find Out More', widget_id: 116684}; For ESEE Knives, Rowen Mfg. Iovito and business partner Mark Carey became familiar with PVD coating while working on the development of a new rifle with Special Forces applications.

Hurry! 9Cr13CoMov: Knife manufacturers recognize the demand for such blades and see their contributions to the available selection as filling a necessary niche. Spartan has recoated some blades in the past, primarily because the owner requested a change of color or to have something etched on the blade. Clip-point: The coating is made to last. One of the nice properties of PVD coating is that it applies uniformly so that you don’t get build-up on corners and edges like some coatings.” IonBond coats Spartan’s blades. Most types of blade steels can be classified as being either Stainless or Carbon steel.  A steel that has the ability to resist rust in the worst conditions while maintaining ample edge retention.  Cocobolo is a tropical hardwood from Central American known for its hardness and density. “It is electrostatically applied in its dry powder form, and it goes on the blade between three and five thousandths-inch thickness. This divide hence calls for an informed choice when you are looking to purchase a knife. I've heard of mirror polishes stopping it, will they? Typical metals used come from the carbon steel, tool, or stainless steel families.  A steel with similar performance characteristics to AUS-8. I've seen it used on guns, but not sure how effective it would be against rust. Stainless is not totally stain proof.” Iovito agreed. It's a durable stainless steel which resists corrosion over time. For those who serve in the military, preserve the peace through law enforcement or knife enthusiasts in general, blades are coated black, Flat Dark Earth, tan or what have you for a variety of reasons, and are permanent fixtures in their complement of working gear. Exclusions apply. ... Oiling is also an extra measure.  An air-hardened tool steel that offers good corrosion resistance and excellent wear resistance and toughness.  A modern engineered plastic that offers high-strength, minimal flex, and optimally lightweight properties. ESEE knives receive the Textured Powder Coat at Rowen Mfg. While the processes are similar from manufacturer to manufacturer, each has its own variation on the coating theme. “We use an epoxy hybrid base with polyester in it,” company President Mike Fuller said. 154CM: This steel is known for its best overall qualities and offers great corrosion resistance, good toughness, and good edge quality. Blade Finishes ... Iseya Molybdenum Steel 210mm Gyuto Knife with Mahogony Handle. Though, this isn't a substitute for proper knife care and there are other methods of rust prevention that work better. Then the coated steel goes through four stages to complete the process: melt, flow, gel and cure. This format lowers the point of the knife for control without sacrificing strength in the tip of the knife.  Cerakote™ has a unique ceramic structure that out-performs many competitive coatings and improves performance in both laboratory and real-world settings. However, when a knife blade is blasted, a surface is created that is less corrosion resistant. Spartan officials acknowledge that the coating of their stainless steels follows the surface blasting of the blades in order to eliminate glare.  A high performance blade steel with superior cutting ability and wear resistance. collapse.
