You can put a great edge on any soft steel, it just wont hold that edge very long. You can tell which ones to stay away from usually by the look of the blade. Tomahawks, timber ratlers, kreigers and more all have that stamped from sheet metal look to them and have that thin near wedge look. I have shaved with a tomahawk and it actually started decently but didn't hold. Out of cheap razors Gold Dollars have been the only ones that have held up there edge near to more expensive brands and have consistent steel when other decent cheapos can be hit and miss. It's always great to experiment, you never know what you may find!
