Treet 100 Carbon Steel"The Black Beauty" Double Edge Safety Razor Blades

I am very positively surprised by these razor blades. I have what I would consider a medium beard growth, my facial hair are not coarse but not soft either, my skin is pretty sensitive. In my Muhle R41 (which is broadely considered an "aggressive" DE safety razor) the Treet Carbon "Black Beauty" works extremely well for me. Very smooth shave, needed only 2 passes for a BBS shave. Usually with other blades I need 3 passes (including the highly praised Feather blades, which are undoubtedly very sharp and great blades but unfortunately cause me quite some skin irritations). I'm so delighted with this combination of razor + treet carbon blade. Hardly any skin irritation, no razor burn and no tugging. Fantastic ... and yes, these blades do rust. They need a bit more care. I usually take 'em out after shaving, rinse and use a hairblower to dry them. That seems to work quite well. I get three fantastic shaves out of one blade before it degrades and I need to discard it. The cost per shave is a few cents. I love that. The extra effort in "babysitting" the carbon blades with the quality of shaves is totally worth to me. As always, YMMV. Like others mentioned, I would suggest to get a sample of these and try 'em out.

The TREET carbon steel “Black Beauty’s”. I was pleasantly surprised, and impressed by how well these blades performed. They are very sharp, but smooth. They do their job well without irritation leaving your face buttery smooth. I used them in my 1965 Gillette adjustable slim razor, along with a Kent shaving soap puck. This combo works so well, that even after three full passes my face was free of any nicks or cuts of any kind. And, when I splashed the aftershave on my face I felt none of the stinging I normally experience with other razor blades. One should remember that these blades are high carbon steel, not stainless; and as such they do rust. Quite quickly as a matter of fact. If you want to use them for multiple shaves, I recommend coating them lightly in a shaving oil. I can honestly say that these are some of the finest blades I have ever used. I highly recommend them.

PROS: Very smooth and forgiving. Ideal for use in aggressive razors. Low cost. CONS: Noticeably less sharp after third pass in my experience, with my particular beard type. Less resistant to rust. Still I'm very happy with these blades despite shortcomings and highly recommend to all wet shavers as we are all different

The Treet Carbon Steel blade is like taking a trip back into the 1950s when all the blades were carbon steel instead of stainless steel. Yes, they can and will rust if you leave them wet or in a humid environment, so take precautions. I always rinse and dry my razor and the blade after every shave so it's no big deal. These may not be the sharpest blades out there like a Feather or Perma-Sharp but for my average beard they get the job just fine. And at their price, even if you only use a blade once, it's still a bargain. I think they're terrific blades and well worth the price.

These are the carbon steel "Black Beauty's" that work wonderfully. I can get 3 shaves out of one if I push one of these blades. I have sensitive skin and no razor burn with these. A nice close smooth shave. They are sharp yet just right. Treet makes excellent blades. I am saving the used blades to give to a blacksmith who makes Damascus knives.
