Ceramic Straight-edge Razor Blades will last longer and keep a sharper edge longer than ordinary straight edge razor blades!
Although initially, the cost is more, you can reuse the ceramic straight-edge razor blades over and over. We have tested these blades in a shop here in Charlotte. The Fabricator has used 1 blade for about 2 months now.
Also, they will fit into all no.9 straight-edge razor blade holders.
