I have four vintage razors. My latest acquisition is a Boker King Cutter (Argentina). It’s probably from the 1980s. It shaves much better than my older vintage razors. I have been straight razor shaving for about a year now, so it’s not technique. My other razors are a Wostenholm Pipe razor, a Spear razor, made in Germany and imported in 1928, and a Swedish-made razor from the same period. Could it be that the steel in the Boker King Cutter is better?
