Not great for shaving
I recently tried these blades in a Gem Micromatic Clog-Pruf razor. They did not perform well at all - lots of pulling, missed whiskers and irritation. I've not tried any other blades in the Gem, as shaving quality single edge blades are a bit difficult to find.
Will probably just stay with double edge blades for now.
