You could try a search in Google on "Star razor blade brit*"
I have a collection of blades, including a few 35+ year-old Wilkinsons and Schicks. They're held in a stack, strung together on a couple of twist-ties.
When the stack gets thick enough, it goes to the recycling center.
I was just so surprised to see a DE blade that was 'hollow ground'
I cant see the "hollow" in the blade but what do you guys think, could you make a DE blade hollow ground?
