The Wave II is a useful and capable tool. I carry one all the time and have never had cause to regret it.

The Wave's blades are adequate, but I agree with others who suggest carrying a stronger blade if heavier work is likely.

For day hikes or weekend backpacks, I take my Wave plus a lightweight folder.

P.S., Les's multitool looked like a Surge to me. Bigger blades. But I've only seen a few of his shows.
