The most significant difference between modern safety razors and wet shaving compared with how it was done a century ago is that today almost all razor blades are made out of stainless steel, while prior to the 1960s razor blades were made out of carbon steel. Carbon steel rusts easier, and so with the introduction of stainless steel carbon steel, despite many feeling carbon held a superior edge, it was almost completely abandoned.
Treet Dura Sharp is one of the few razor blades still on the market that’s made out of carbon steel. Manufactured in Pakistan, it is coated in PTFE (Teflon) which provides some protection against rusting while also giving a sharper, longer edge over just carbon. Having never used a carbon blade before I was curious how well it would work. I’m sold.
I don’t know if the razor is quite as sharp as a Feather, nor quite as smooth as the Gillette Silver Blues. But they have been some of the most enjoyable blades I’ve shaved with, and they are in serious competition with those two for the spot of my favorite blade. They feel sharp, gave a close shave with no irritation, nicks or bleeding, and they have a satisfying feel (and sound) as they cut through the stubble. The result was a good shave throughout the week, though they had begun to lose some sharpness by the fifth shave or so, and a blade that even if not the best in one category did everything well in an enjoyable, balanced package.
The drawback here, of course, is that since it is carbon steel whether it would rust. I had heard a few different methods of preventing it, with the two leading methods being simply making sure it was well dried (I did this by shaking and blowing it out), or by dipping it at the end of the shave in some rubbing alcohol and letting it air dry (the idea being that the alcohol will displace water, and then dry faster).
I tried both methods, here are the results:
Rusting was minimal in both cases, confined to where the razor head clamps down on the blade. There is slightly less rust using the alcohol dip, though during the alcohol week I found myself enjoying how the blade aged through use somewhat less than without. If any actual difference occurred, then to me it would seem that the blade ages better naturally rather than trying to extend its life.
The rusting though is so slight that unless you intend on using the blade longer than a week there seems little cause for concern. They are cheap enough that even if you only shave one or twice a week and can extend the calendar day use of a blade longer than a week then if rusting is a problem you could replace it more often without much added cost. For me though it’s not a problem, I change blades every week and if it can survive in Virginia then I suspect it can survive most places.
I highly recommend this blade. Having tried a fair number at this point, it is easily in my top three and might even be my favorite. It’s sharp, smooth, and enjoyable. With ten blades a pack I’m looking forward to eight more weeks of fantastic shaves.
