When it comes to SAK's, I have always been in the '58mm-is-great' camp. My only problem with the 58mm line though, is that I like to carry my knives in the right front pocket. These tiny 58mm SAK's though, just disappear in the pocket and I never physically feel that I am actually carrying one. To me this is important, it does not need to be bulky, but I do like the reassuring feeling of carrying a knife. In order to solve this problem I started carrying 84mm SAK's that include the small pen blade. In use, this gives me a 58mm 'feel' with the benefit of a larger frame. I must say that I am really enjoying it and for now I don't see myself going back to a real 58mm SAK anytime soon. Does anyone else have similar experiences? Did you ever upgrade or downgrade for reasons that have not much to do with the actual capabilities of a knife? I hope all of this makes some sense.
