I obviously paid no attention to the ebay title listing and ordered 100 Perma Sharp single edge blades. The double edge blades just cut in half. Any way I can still use these bad boys? What would you use them in?
Believe it or not, you can put them in a DE razor. I snapped a blade and put 1/2 in three different types of razors, and it gets locked down tight and shaves just like there was the other half in there. It worked in a Ri,mei 3 piece, a Mingshi TTO (terrible razor for me BTW), and a Gillette Click.
I did it to try and determine the longevity of a blade. I didn't want to confuse one egde for the other. By having one edge only, I was able to see how that one edge lasted and then it was a pretty small assumption that the whole blade would last twice as long.
