Guys, been straight razor shaving for a little while now and have a bunch and want to start the task or honing myself.

Don't want to hack up my good blades, looking for a recommendation for good ones to practice on. Not sure if getting some $6 specials on ebay will even hone right or if the best entry level one just to learn on even if it doesn't hold an edge well is something cheaper like a golden dollar.

Then any special youtube videos or references you guys have. Just looking to touch up after pasting isn't enough. I figure restoration should come later.
