The two main contenders were the Rebar and the Bond(which I got). The Rebar has replaceable wire cutters and locking blades. The replaceable cutters were a little interesting, but I had my main Leatherman > 20 years, and though the cutter wasn't pristine, it still worked fine. Having screws there adds a failure point for dubious gain. If you're really using the cutters that much where you'd have to replace them, it might be a good idea to carry a dedicated tool.
The locking blades are a good idea, but I don't use the tools aside from the pliers much in a leatherman. I have a fixed blade knife I typically use for cutting, and a Swiss army for various tools. The leatherman steel is also too hard. It was on the originals anyway. I had broken almost every tool in it from abuse. If I tweak my Swiss army, I can hammer it back in shape. I buy these things to abuse. They're the tool you have with you, and get adapted to the task. I need something that can stand up to abuse.
