the purchase I described in May 2009 is in my razor now and is almost too dull to use. I say useable because I was only able to endure 2 or 3 shaves with the Dorco blades and will likely throw the rest away.
So that's 40 blades over 3 years? It sounds hard to believe but I haven't shaved with anything else except on business trips or vacation when I use the remaining cartridges from my old razor. I do that because they are easier to fly with (no bag checks) and because I still have some left over from before I got my Merkur razor kit. When those cartridges are gone I'm not sure what I'll do.
At this rate it looks like I'm going through about 12 blades a year. I only shave between one to three times a week and I have a pretty light beard so that helps. I am about to buy 100 Feather blades from West Coast Shaving for $40.00. When I started shaving the Feathers were too sharp for me but now I have the touch and have found them to give the best shave and to last the longest. It looks like I won't be buying more blades for about 8 years or so.
