M4 Steel Knives

M4 is a tool steel produced by Crucible Industries, a company known for the production of some of the best knife steels on the market today. M4’s incredible edge retention and overall hardness make it a steel of choice for cutting contests. You’ll often see CPM-M4 used in popular custom knives and in production models from big knife brands like Spyderco and Benchmade. If you want to learn how it stacks up against other steels, check out our Best Knife Steel Guide.
