Supply blade review

Easy to use, and they give a very close shave. Love them.

Still haven't finished a pack after 6+ months

I use these for about 4-5 shaves each and have not gone through 20 yet after 6+ months. The disposal on the key is a big plus.

Great shave every time

I’ve used multiple razors and used different brands throughout my shaving life. In each attempt to achieve a good shave and less irritation I haven’t found that yet until I found supply. This single blade razor has really changed the way I shave each and every time, I have no more irritation because the razor truly just sweeps away the hair in one stoke. I am extremely happy in the quality that you get when you buy the razor and also the blades and how long they do last unlike the other competitors. I will use this forever razor years to come, thank you supply and your craftsmanship.

Blades Better Than The OEM Still Makes-Phenominal Customer Service

I am a long-time injector user (since mid-1960's), and have tried/used all of the shaving gimmicks over the period (single edge, multi-blade; can anybody remember the Techmatic?). There is a reason why I've always returned to the injector-once you learn how to correctly shave, it is the best and one of the most economic methods out there. The trick is learning how to use the tool (yes, it's a tool) correctly, prepare your face and enjoy the time it takes to get a great shave. Can't stress the latter two enough-this is not a slam-bam, once is enough process

Being a long-time user, I saw the various manufacturers and supply of injector blades disappear-ultimately leaving the OEM of the process as the only supplier. You had to hunt for replacements and sources whom had them: when you ultimately got what you wanted, the quality was very poor for the money.

I discovered the blades by accident-it was a great shaving from then on. I'm a geezer that still has a tough wiry beard: I can get 5-7 shaves out of a blade before replacing, vs. the OEM's 3-4 (if I was lucky). The price is right also.

I did have a problem with the dispenser-the loading mechanism is weak, and broke-left me four blades which I could not use. I pointed that out to Supply, whom promptly mailed me a replacement pack-no charge and with good cheer. Also stated that they are addressing the issue (others had the problem) and hope to have resolved in October.

Guys-I might be an old bag of wind, but I'm not drooling in the corner yet. This blades are the way to go, whether you use an OEM handle like me/one of the new Supply tools. Not only will you get a great shave, you will save a lot of green over time. That may not be important now, when you are drinking craft whiskey and jetting off to exotic places: but, when you have to pay for orthodontia, teen age car insurance, college and replacing that roof, you may get it.

Second Time’s a Charm

My second set of blades are fantastic. I had a problem with some dull blades my first time around, but this has been rectified. Thank you Supply.
