Crucible CPM 3V is my favorite blade steel.This high carbon alloy steel is extremely tough and has enough chromium to have some corrosion resistance. Grind the edge thinner than normal. The steel is tough enough to support a thin edge.
Pyrovan and Vanadis 4 Extra are shown in the table above for comparison purposes.

Heat Treating Information:Preheat: Heat to 1500-1550°F. Equalize.
Austenitize: 1875-2050°F, hold time at temperature 20-45 minutes. Quench in air or positive pressure quench to below 125°F or interrupted oil quench to about 1000°F then air cool to below 125°F
Temper: Three times at 1000-1050°F 2 hours minimum each time.
Cryogenic Treating: May improve long term dimensional stability by transforming retained austenite. Any cryogenic treatment must be followed by a temper.
