Let's see the goodies you got this week!
Saxmoore, razor blades were broader 70-ish years ago but from then on classic razor blades haven't changed. I'd say use it for fun but today classic razor blades are much more inexpensive than they were in depression/WW2 era.
My wife found this at a garage sale this weekend, which brought up some questions. Were razor blades thicker 30 or 40 years ago? Could you sharpen them because they didn't have any extra coatings on them? I'm still pretty new to all this, but I'm having fun learning about history, etc.
There have been several threads posted on hones and honing for DE blades - just use the search facility and they will pop up!
Cordially, AvT.
