Skunkabilly,<br>I've got the Wave Tool Adapter Kit for my Wave, and I'm surprised at how versatile it can be. I ordered a combo sheath from Leatherman that securely holds the Wave and Tool Adapter Kit for excellent convenience. <br>Anyway, back to your inquiry, I would probably go with the Crunch or ST200, as a complement to the Wave. The Crunch because of the vise grips, and the ST 200 because all the tool blades lock. The Wave is an excellent tool, but for heavier duty tasks, you can't go wrong with either of the other two.
