You make a good point. Leaves me wondering if, in 200 years, James will be forgotten like the rest of us or if his razors and fame will live on, a sort of modern Stradivarius -- his razors by then selling for obscene sums.
Stradivarius cranked out 1100 instruments. There’s some that think he farmed out much of this work.
It looks to my limited experience that what’s living on is the 3 piece razor. Not many innovations, just variations.
