I would never spend $100.00 on a strop. The two vintage shell strops cost me less that$25.00 combined. I hit garage sales, flea markets, antique shops & junk shops always looking for vintage shaving gear. I got my shell Koken for $20.00 at an antique shop & my Jager Barber Supply Shell for $5.00 at a garage sale. These strops have a few nicks & dings & I sanded the bed places to smooth them out then I treated them with Ballistol. The Jager had been in an unheated wood shop for around 30 years & was really dry. By slowly treating it with small amounts of the Ballistol it now feels like a new strop. If you don't feel good restoring your strop there are guy's on here that would do it for you.
