I'm in the same boat as Mike. And him being a Master at boats puts me in a great place. But thats another story...

I have so many shave-ready razors I could sell off all my stones and never need to hone again for the rest of my life. But, We have people like Victor who makes razors and loves to test his edge. Victor can get 100+ shaves easily on one of his razors. But for the guy who is somewhat new to using a straight, I can see a refresh needed at 15 to 20 shaves. JMO.
