Steel Materials

You can’t hone a good blade from bad steel. That’s why Case uses only premium quality steels, ordered and tested to fit our demanding specifications. These include:

Chrome Vanadium (CV) – a special formula of alloyed cutlery steel known for its ease of re-sharpening. A quick touch-up will bring back a chrome vanadium blade’s original sharp edge. (Extra care is needed with CV. Keep a thin film of oil on the blade to maintain the finish of the steel.)

Case Tru-Sharp™ Surgical Stainless Steel – a special high-carbon steel that helps the blades hold an edge longer than conventional steel. It also offers extraordinary blade strength and corrosion resistance.

ATS-34 - ATS is the brand name for this premium steel. Its reputation for edge retention is second to none among the stainless varieties. It is manufactured with very few impurities, combining three principal elements; carbon, chromium, and molybdenum. Added levels of carbon and chromium enhance the steel's hardness and rust resistance qualities. Re-sharpening can require extra effort.
