It seems like more and more folks are collecting the TL-29 patterns these days, having been in the trades a good portion of my work life it was a pattern I both loved and despised. I carried one on and off until the the first full size Leatherman came on the scene. I've never had a real nice electrician's/TL-29 just work ones with sawcut delrin or black composite scales.
The love/hate relationship came from the design feature where they put a sharpened edge where the side of the screwdriver was. I still have one or two in the tool boxes I love the pattern for what it is and represented to me as a tool/knife I've used for a good portion of my life but I'll always wonder why they designed it that way.
Now I don't know about anybody else but when I start a screw I always hold the screw between my thumb and forefinger in one hand and put pressure on the flat of the screwdriver but most times because your in an open slot with a screwdriver tip that is usually substantially thinner than the width of screw slot it always slips out.
Usually not a problem beyond annoyance but when you're presented with a sharpened edge it becomes hazardous and I've sliced open my thumb enough times that I made sure there was always an orange handled 4 way screwdriver in my pocket when ever working.
Nice little collection you have there, I really like the way the RR model looks with the jigged bone scales and the matchstrike nailnicks, I've never owned an RR I may have to get me one.
Here's the last one I bought while writing a long time ago and I really liked the features, especially the bubble level it was great for leveling breaker boxes, conduit and switches/disconnect boxes. This was a great knife unfortunately it was made somewhere other than the US. The knife was made surprisingly well back in the 80s when I bought it from a Guttman(sp) catalog.
I would love to see a custom version of this knife.
