S30V Steel
We consider this the absolute best blade steel available, and it is made in America. S30V contains carbon as well as high amounts of Chromium, Molybdenum and Vanadium. This steel combines fantastic edge retention and high ductility combined with corrosion resistance. Double-tempered - it can be hardened to a Rockwell hardness of Rc 59.5-61. However, it is difficult to resharpen yourself, but we do offer sharpening services for a nominal fee.
420HC Steel
This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.
