True story, the most inexpensive maintenance tool is a pasted strop. I like CrOx for a quick refresh. They seem to work best as a little bit often, as opposed to trying to strop back a dead edge. It's hard to be able to tell when to usr it in the beginning, because you are not sure if it was a dull edge or your technique was just a little off. There has been much controversy as to how much is too much. Many claim you can use a small amount on a strop daily and everything is just fine. You can also touch up with a barbers hone or a 12K or other finisher. Unless you are restoring a touchup will often be all that is needed.
