This is a 7/8 Reynolds,that I reworked and rescaled for a member here.This style razor is a concave grind (some call it a frameback I call it a sling blade)These are excellent shavers,and really hold an edge,also very friendly to hone.The pivot is adjustable tension.I just polished the blade and rescaled,and honed,it was in pretty nice shape as recieved.
