I joined the Dollar Shave Club last month.

For a dollar a month (plus shipping — so actually $3 a month) you get a pack of 5 new blades delivered automatically in the mail every month.

The “Humble Twin” blade is $1/month. You can upgrade to the “4x” blade for $6 or the “Executive” for $9.

It’s a twin blade like they used to have back in the 80s. It gets the job done. Use it for a week and replace. It’s always sharp.

Back in the day, the ads were all about how great an innovation the twin blade was. “The first one lifts, the second one cuts, giving you the closest shave….”

Then, sometime in the 90s I think, they decided that, “three blades are better than two.”

I’m not sure when they started making razors with 4 blades. I tried one once. It was just too wide to fit between my nose and mouth. I ended up with a little strip of thin moustache under my nose that had a disturbing Hitleresque quality to it.

Now in the skin care aisle, I see razors with 5 blades.

The Dollar Shave Club Executive has 6 blades. I’m not sure why. It just does.

Somewhere in the dark recesses of the Gillette company compound there’s probably a guy in a dark room trying to come up with the next razor innovation. His face is lined with concentration. He’s muttering, “I wonder what comes after 6….”

The basic twin is plenty if they’re sharp. The Dollar Shave Club’s twin is cheaper than buying them at the grocery store.

If you shave and you’re tired of using dulled quintuple blades I recommend it.
