Joseph Rogers & Sons of Sheffield England has been making knives since 1682. After 335 years of making knives of all kinds I suspect they know a thing or two. Their pipe knives are the best designed of any. The blade has a very sharp edge but no point. This way when reaming your pipe you will never gouge the bowl. All are hand made in England.
