My daily setup is a Rockwell 6S, #6 baseplate, and Feather blades. I dropped the Permasharp blade in on Monday, with about three days growth. Extremely smooth and comfortable; possibly better than my Feathers. The four following shaves (Tuesday-Friday) were also very good. Saturday (sixth shave) was dramatically worse: it was like shaving with a paint scraper. As long as I don't try to keep it in the razor too long, the Permasharp may be my new favorite blade.

The Perma-sharp blades On my skin cut my beard or wiskers the best. I know there are sharper ones on the market, but on my face these blades cut, and leave my skin smooth.

I have been trying many different razor blades to find the right one for my sensitive skin with having coarse hair. Perma-Sharp blades have been the most effective for me to this date with very minimal irritation compared to others that I have used. I typically get three shaves out of the blade.

The blades are extremely sharp, if you're new to shaving be wary of accidental nicks. That being said they cut quickly and easily, and certainly last. They cost a bit more but seem to last longer
