I left it out previously but it has to be noted that flat-bar type pry bars are easy to modify. The material is typically a mild alloy tool/spring steel that can be worked with hand tools like files and hacksaw but has enough carbon and alloy to allow a considerable degree of hardening if heated and quenched.

I have often ground or filed an edge for various tasks and have used the basic bar as raw material for home made tools, in one case a froe, and other specialty tools. In a couple of cases I have case hardened an edge to get a more durable edge. Just make sure you case harden after you get it to the shape you want. Particularly if your using only hand tools.

The flat bar new is a fair bit of decent quality steel cheap. Buy them for a buck or less a pop at a flea market or garage sale and you have something to work with. The steel lacks enough alloy for extreme toughness and carbon to hold a fine edge but it can be, as mentioned, modified to some extent if you willing to go to the trouble and it is good for a lot of tools and fixtures.

Making and modifying your own tools means you can get exactly, or at least closer to, what you want and get it inexpensively.
