A long time ago, I inherited some DE razor blades from my Grandpa, who was born in 1917. However, there were no razors included, and my mom suggests that her sister's family pilfered them. In any event, this is what I've got. The Marlin Rifle blades are much thicker than current blades sold today, and given that it's non-stainless steel, even though these were secured in arid California, it's a cheese-grater to the face. I can't recommend trying to shave with stainful vintage razor blades.
