100 Treet 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.

Been using Derby stainless. Was surprised how much smoother these blades feel! Will see how long they last, but the price is good enough to replace as needed!

I love that these are so cheap that I bought a 100-pack despite and because of reading a review that scored them 0/5 and worst ever. It my Facon razor, a relatively aggressive well-made cheapie, these are not good. In my Merkur Futur (and clones), this is quite good for the 1st 2 shaves. Not so good for the 3rd shave, I switched to a Feather Popular razor for this and had an excellent 3rd shave. I still prefer other cheap blades that are trivially more expensive like the Permasharp, Voshkod, Gillette Wilkinson Sword, etc. However, for those who want to see that a blade some hate can still be good if used in the right razor for some people, this is a cheap experiment.

We all know that everyone is different, and what I like, may be terrible for the next person. I have a very coarse beard, and very sensitive skin. My go-to blade has always been Nacet. It's what got me to effectively wet-shave, and still works amazing for me. I've noticed I can't use platinum blades, as even if I get a really good shave, I'll be red and irritated a couple hours later... So I thought I'd give Carbon blades a try. I'm glad I did. They're surprisingly smooth, and surprisingly sharp, but not too sharp as to cause irritation. They seem like a "forgiving-smooth-blade." Which will make sense to most DE/wet shavers out there. Yes, unfortunately they do rust. And they rust somewhat quickly. (that's a used blade in the photo) but it seems like most other blades, I'm able to get three shaves/days out of the blade before I throw it out. (I haven't pushed the limit on these blades yet, I've kept them at three total shaves.) For the price they're definitely worth trying. I've just ordered more since trying them the last few weeks. If you're new to wet-shaving, definitely check out some beginner YouTube videos. It's a different type of shave, but so much better than plastic cartridge shaving. It just takes a learning curve to understand and get better. Try these blades. I'm hoping you'll like them too. Best of luck.
