I have one of those in my pack, along with an extra 9" blade. The stock blade is too short for a lot of stuff.
Funny, I do exactly the same after finding the 6" blade a little short for taking off skull caps. Along with a fixed blade or two and my Leatherman all in the field kit. Probably a small folder with a clip in my pocket.
While I have one because they're handy, the recip blade isn't the best for a hand saw. It's made for high speed cutting and it doesn't cut as fast as the sharp toothed type that Silky or Sierra use.
I've tried a few different types of blades on mine. Still looking for the best bone cutter, but they've all worked reasonably well.
