If a good quality, inexpensive sharpened prybar is what you're looking for I'd recommend a Glock field knife instead. It's surprisingly light but pretty much indestructible and comes with an awesome lightweight sheath (much better than the heavy steel scabbard on the Mauser bayonet).

Or an AK-style bayonet. Cheap and very durable. I keep a Bulgarian AK-74 bayonet in my toolbox, it makes an awesome heavy duty tool but it was a pain to sharpen for the first time. Those things were never really intended to do much cutting but the blade is capable of taking a decent edge and the point can be used to pry or dig with little risk of damage. Also, the scabbard and bayonet can be used as a wire cutter - quite effective in that department.
