Merkur (15) these are the only blades that consistently 'go the distance' with me. No wonder they are the only blades that the top shaving emporiums sell. ie DR Harris,TOBS,Geo F Trumper etc.....
Half shave with Feather and half shave with Gillette Nacet.
Feather was sharp and provided a nice shave with little irritation but I felt it tugged a little more than I would like. The Nacet performed better. It was much smoother than the feather but provided just as close of a shave.
Tossed the Feather and kept the Nacet in for next shave.
