I have a Wave and a Gerber. I bought the Wave at a Pawn Shop, lifetime warranty included.....Always keep one in the car.
Leatherman has a no hassle service plan and has been very good. My wife sent my Gerber into cold storage one winter in a suitcase and it rusted a bit.
The Gerber factory rep I met at a hunting show gave me grief about misuse when I asked about how to clean it.
I met the Leatherman folks at the same show and asked about a small flaw, told them my Pawn Shop story. The rep asked to see the knife and then asked for a business card and took out a zip lok bag. Two weeks later a new knife showed up... Can't beat that.....They could have just replaced the flawed blade or honed it or told me how to.
About a year later we used that same Leatherman to repair a base amp for John B Williams during an impromptu jam session in an LA hotel. Very fun night...
Without the Leatherman there would have been no music.
Figure out what tools you will use most and try them. I found several screw driver tips are awkward on different tools. Then check how it fits your hand. Don't buy a Knockoff.
