Treet Platinum. (5) Started sharp and smooth...by the 4 shave was getting rough...shave 5 and done. Probably the shortest life for a blade that was good from the gate.
Today I am tossing my 15th use of a Feather Professional SE blade.
I was trying to go the whole month of Feb (for the one blade challenge). I was using it in a Mongoose SE and had some great shaves with it. Suddenly it no longer was performing as I would like it to, so out it goes.
