Our blades are twice as thick as our competitor's razor blades - giving a more substantial, effortless shave.

Great Blades

Never had such a smooth shave

Rough Start

My first two shaves were terrible. The blade wasn’t cutting. I must have dulled the blade when inserting it. My third shave I cut myself 10 times. Yikes! I hung in there and eventually figured it out. The blades are so sharp it takes a very light touch. I’m hooked. Great product.

Blade cartridges

Great supplies from Supply!
Work exactly as advertised and great value compared to other options on the internet.

Single Edge Blades

The Single Edge Injector razor blades provide a smooth, comfortable shave when used with the Supply Single Edge razor. The "No Touch Blade Change" is the safest, most efficient design in the industry. These very economical, durable blades provide me at least 10 great shaves per blade. I highly recommend these razor blades.


Ordered a razor. I had a small operator issue (probably me). Sent an email and a day or two later I was sent a new razor. What? 2018 and some business actually cares??? The razor is a work of art. It reminds me of my first single edge Schlick from the 60’s when I first started shaving. Obviously this razor is light years ahead of the old Schlick. Based on the way the young people who started the business, they will be successful (wildly, I hope). Kudos & I’ll be back to patronize this small business again and again.
