Big fan of the Leatherman Wave here. It has changed, though. The earlier releases had a larger scissors, but no lock for the accessory tools. The later version with smaller scissors is nicely done with those accessory tool locks and the bit sockets. I do find the smaller scissors not as effective… but then, I see them more as emergency use and not for long cutting sessions.
Anyone here use the SOG Powerlock? It’s not as well made as the Wave, but those pliers… are amazing. Compression mechanism for added force. I keep one for that reason. But for EDC, the Wave rides the tide. 
Good to hear that, coming from someone who puts a Wave to use on the job. What kind of issues prompted a warranty claim? I find the Wave so very solid. I just wish there was replaceable wire cutting blades. If they get damaged in any way, that’s it. Unless you have a means of grinding and sharpening.
I have 3 of them (2 old style, 1 new style). They’d gotten a bit loose at the pivot joints. No effect on operation, but wouldn’t stay tightly closed. I bought one of those Torx security bits for tightening, but it wasn’t quite the right shape. I had to finagle it to tighten just enough. Is there a better bit for this?
