I have used a number of steels in the past some just to try them out. I'm carrying a BackPocket made with CPM M4 and a trapper made with CPM 440V. Different steels are fun to play with but if I'm going to carry and use it I want CPM 440V with a ground finish. This m4 is not bad either but it will rust. That doesn't bother me but it would a lot of people.
