I'm also a recent convert to the old time "pocket" knives. The "black tactical" thing is wearing me down, they just don't seem to have the "soul" or character of a classic stag or bone handled slip joint knife. While I usually have a tactical type knife on me, the one I find myself eyeing and playing around with when no one is looking (I hope!) is one of my Moore Maker's with yellow jigged bone handles in medium trapper, stockman, swell center, or sow belly whittler patterns. One of these or the Schatt & Morgan with antique green bone handles with ATS-34 blades in a serpintine stockman pattern rides in the left front pocket always. I'm currently in the market for a good Copperhead pattern with stag and carbon. Idea's for this one? A fairly local B&M store has recommended a BUCK CREEK as a high quality knife which is tough and uses good carbon steel. I can't recover much info on them, so am a bit hesitant to buy one instead of the German Eye Copperhead he also has in stock. German Eye brand seems fairly well known and respected.
A side benefit of the slip joint knives is their charm when around sheeple. Pulling one out and using it in front of others doesn't cause alarm, and in fact can spark some dialogue about knives when someone comments, "That's a pretty neat old knife?" This is an opportunity to make headway for a knifenutt's image in todays post 9-11 society.
As to the comment about the usability of the slip joints for mundane everyday cutting chores, the versatility is hard to beat. After carrying single bladed folders for so long I recently faced a real dilema. Having the need to cut a hole in a shoebox, I eagerly pulled out my Moore Maker trapper pattern and as I began to open the blades realized I HAD A CHOICE! I actually could choose which blade style would best suit the job at hand. I reflected later that if the cutting chore had been difficult enough to dull the one blade, I would still have an unused sharp blade handy.
