I have two horsehide shell strops, both at least 85 yrs old. One even has my last name stamped on it. Someone, maybe a distant relative ran a barber supply co in NYC back then and had his strops stamped with his company name. Both by chance from eBay and in remarkably very good condition. Even the linen strops were on good shape, just a little scrubbing with soap and water. Shells treated with neatsfoot oil and both are in alternate daily use. Alternate just for the heck of it. Extra note: I prefer bench stropping. Have no easy place for it. Cut some thin fiber board the width and almost as long and secured them with Velcro straps top and bottom. Results two hanging bench strops. Both with different draws and I have no preference. Just happy to have that addiction done and over with. If it were only that easy for soaps and creams, brushes, scuttles, mugs, bowls, razors and what have you.
