So I have an abundance of knives, and with a baby on the way, I have to get rid of some. The PM2 is one of my favorite models, and I have a few sprint models I have recently acquired in 4V and CPM Cruwear. I wanted to see which most of you prefer in folder, as I have used Cruwear a bit in the past but I haven't used 4V at all. I really prefer a bit more toughness over edge retention, so a blade that is less prone to chipping is important to me. Thanks in advance for any and all input. I suppose I should add too that I have another new PM2 in 20CV, and while I have a lot of experience with the steel and really like it, I could be persuaded to part with it instead of the Cruwear or 4V models.
