Sunday Shave- Treet 7 Days Platinum
There are several brands with similar sounding names. Gillette has four blades sold under their 7 O'Clock brand. Durablade sells 7 AM Hi Platinum. Treet sells 7 Days Platinum.
Today, I am evaluating the Treet blade. Treet produces a wide variety of blades: carbon steel, stainless, and platinum coated blades. Prior to this evaluation, I was always suspicious of the quality of Treet blades, but after several successful tests, that my opinion of Treet has changed. They make blades that can compete with many others in the marketplace.
I began today's shave with the Merkur Platinum blade from the previous shave still in the razor. It was still sharp and smooth. I could have easily used it for another shave or more. When I replaced the Merkur blade with the Treet 7 AM blade, I detected little change in sharpness or smoothness. I continued through my four pass shave including buffing strokes during the clean-up pass. I was easily able to achieve a near-BBS shave. When I applied witch hazel after the shave, I got moderate feedback. This shave was quite similar to the one using the Merkur blade.
Based on the results of this shave, I am going to rate the 7 Days blade the same as the Merkur blade: 4.5 sharpness and 4.25 smoothness. While it is possible that the blade is the same as the Treet Platinum blade, I rated that blade slightly less sharp (4) and slightly smoother (4.5). Thus, they might not be the same blade. The 7 Days blade sells for $9 per 100 blades making it a bargain for those who do not need the very sharpest blades. If the blades last for 7 days of shaving as implied by the name, it would be quite a bargain.

The next group of blades to be tested are all from Derby in Turkey. While most people are familiar with the Derby Extra green and Derby Platinum blades, the Derby BlueBird and Derby Usta blades are less well known. Also Derby has recently introduced two other versions of the Extra blades. One is the Extra blue, which might be only a difference in the number of blades per tuck (blue 10 vs green 5). However, there is also an Extra orange version that indicates it is Platinum coated and does not mention the complex chromium, ceramic, platinum, tungsten and polymer coating used on many of the Derby blades. I will be comparing the BlueBird and Usta blades to the Derby Premium using face-off shaves. I will compare the Extra Blue and Extra Orange blades to the Extra greens using face-off shaves.
