I used to love the LM Wave but over the years, the pivot tend to get loose and there will be some play hence I pass it to another friend.
I was issued with a SOG Powerlock while I was in the military and it has been like around 8 years. The pivot is still great and the gear systems really help in the gripping force. The exposed gear when the tool is kept is a very good self defense tool!
Currently I have like at least 4x SOG Powerlocks which I spread them all in my home, vehicles, workplace and my EDC bag. Another thing I like about the SOG is that you can replace broken tool or change the configuration of the tools in it. I have a set that I swapped out all the knives or cutting edge tools inside for my overseas travelling usage.
I have a LM Skeletool too and its a minimalist setup, the LM Bit set really works well with it. Got the LM extender and its really a good combo in my EDC kit. Only problem with the Skeletool is that the plier tips flex when I need to twist or bend something in certain task I do. The major plus for the Skeletool is the size and thickness of the 154CM blade!

For those that would like to get the Gerber tools, do take care if your is the beadblasted version. they built up rust easily then those blade version.
