So I am looking for some understanding on knives. My only knowledge on knife steel is 154cm and 420c. Other than that I know squat. So what are some good steels for knives and what are some to be wary of. By the way this would be for like a work knife and EDC. Something that will take a great edge and keep it. I don't want suggestions on knives but for what steel this knife should be made of.
