I found that they simply would not take a good edge. That's AFTER addressing issues like asymmetrical spines and intrusive stabilizers and shoulders, and blade twist. Seraphim I think honed two of them and got them to shave. So YMMV. The strop will work for your beginner strop. You will trash it pretty quick anyhow, learning to strop. By all means, keep them for stropping practice. You could even do a couple of practice runs shaving with them. Dull the edges even more for safety, if you like, so you won't get any cuts.
Check out Larry's Sight Unseen shave-ready vintage razors at www.whippeddog.com. That is probably the cheapest way for you to get in the game.
