Of the few charts out there, I haven't seen this one in awhile! And I had been looking recently. Interesting that discussions about the Treet Dura Sharps come and go occasionally, but they never worked well for me. Now I see that it's because they are narrower, but I have an appropriate razor now and they are sitting on my desk for some reason...I think Gillette Sputnik blade are put have none to confirm this, I ordered some 2 days ago so it will take a couple of weeks to confirm them, they are coming from Sweden. They are the same width as a Kai SS blade.
I think one of the fellows on B&B(?) did some research years ago so it is reasonably accurate I'm thinking!

Gillette Sputnik are reported to be, they are on my to try list. I have found more blades to be narrower than wider.
