Most of my pocket knives are slipjoints, many of them older ones. Only have one "modern" one hand open/close model, a Boker Gent II, and it's smaller and thinner bladed than many typical newer type knives. Favorite patterns are copperheads, scout/camp, and cattle (equal ends aka cigar stockman). Never really been attracted to tactical style knives, most just aren't shaped like I want. Two one handers that I do lust for are the Case Slimlock and William Henry T10 Lancet, both of which are too expensive.
