CPM 20CV is a steel created by Crucible to be excellent at resisting wear and corrosion. It's balanced with good toughness as 20CV combines vanadium for edge retention with a high percentage of chromium. It's comparable to Bohler's M390 stainless steel or Carpenter's CTS-204P.  These super steels share their composition and are regarded as the best knife steels available, however due to the raw material cost they are often only seen in smaller pocket knives

This premium "super steel" is  made up of 1.9% carbon, 20% chromium, 4% vanadium, 1% molybdenum and 0.6% tungsten.

Toughness. The combination of carbides in CPM 20CV makes the blade tough, but not as resistant to breakage or chipping as other premium steels.  Although this steel is tough, this blade is not designed to chop at bones.

Edge Retention. Critical to the kitchen, CPM 20CV is one of the best steels for retaining an edge. The CATRA test, which compared 20CV to 440C, rates CPM 20CV 180% better than 440C in sharpness and edge life of a blade. The higher percentage of vanadium in this steel creates a fine grain structure to better hold an edge. Adding molybdenum increases the strength needed to hold the edge over time, and the added tungsten also helps keep the edge.

Your knife will have its final edge applied using a CBN wheel at low speeds.  It should only need to be honed on a rod or touched up on a high grit stone.

Stainless/Corrosion Resistance. The high percentage of chromium with a bit of molybdenum makes 20CV one of the best high-end, corrosion-resistent steels used in knife blades today. Higher chromium amounts allows some of the metal to form a protective, passive film of chromium oxide that repels rust and prevents staining.

Handle Options

**Gemstone composite Info**
The Gemstone handles are made of 80% real stone dust mixed with acrylic resins to form a corian like material which is very hard and waterproof that simulates the natural stone.

**Resin and Stabilized burl**
Stabilized Burl is combined with our resin to create these one of a kind knives, no two batches of resin are exactly the same!

** Resin cast Stabilized Pine cone handles**
These stabilized pine cone handles are cast under pressure to force the resin into all the nooks and crannies of the pine cone which is then shaped and polished by hand.

** Stabilized Wood**
Our highest end old growth burls are selected and then stabilized.  The process of wood stabilization forces liquid resins into the wood under high pressure. The resins completely impregnate the wood, and then cure, so the wood now resists shrinking and swelling with the weather as well as taking on water.
