I don't think I will ever find the "perfect" knife since what I carry seems to change with my mood, as well as what I will be doing.

Like almost everyone else, all of my Busse and kin are quite capable of doing the job whether they have been used or not. Same with the folders I own. I do keep some cheap blades in my truck, so if they get stolen, I won't feel bad.

I also have a few blades which have tasted blood, but not been used, if you know what I mean. ;-)
