It is not particularly expensive, so it might be worth a whirl. However, I am not sure that it will do anything that any of several pry bars obtainable at the local home store will not accomplish just as well. Any of these gadgets would be a nice companion to a knife.

I use short (8 to 12 inch) pry bars when excavating paleontological specimens, usually from compact gravel deposits, and I beat them up pretty hard. I have yet to damage one to any significant extent. Basically I resort to the pry bar when I might overstress some of my more delicate tools, like pointing trowels.

When not in use, I keep them stashed when they might be handy in the event of the next earthquake. I stash a pry bar and a 3 foot crowbar just under the bed. Others are in the vehicles, in the workshop, etc.
