Really, this depends on you. Do you want to be able to maintain/hone your own razors? Can you afford/want to send your razors out to be touched up?
If you would like to maintain your razors, I would say invest in a barber hone that has a good reputation, like a Swaty, etc. If not, Pick up another razor, so you have a backup while the other is sent out for touch-ups/honing.
For me, it was a logical step to hone/maintain my own razors because I do that for my pocketknives/kitchen knives, etc. Follow your instincts. If you want to be self sufficient, do the research, and ask people. That's what the mentors, etc are here for on
SRP. Don't be afraid to send a PM. We would be glad to help you in any way possible!
