I have two Hart razors-one first generation pre jib square point and a second generation round point, both 6/8. The second generation appears to have a greater hollow to the blade and shave substantially better for me. Does anyone know if the grind varies from razor to razor or if there was a change from the first to second editions? Or dis some of the first editions need additional honing. I understand these are artisan products and as such there may be some variations but curious if anyone else has had a similar experience.
