I've been picking up a number of razors from flee markets and antique shops, refinishing them and using them. Yesterday I picked-up this 65 gram wedge with an ivory handle. Its labelled Joseph Stones and Son, Sheffield and I'm trying to figure out its age. I haven't found any mention of the manufacturer in any of the Sheffield listings. It shows almost no wear and my inclination is to sharpen it up and use it. Any input would be welcomed.
