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

I've tried about 3 or 4 of the other popular DE blades and these have performed the best. Highly recommend them!

Yes, these are smooth and sharp. These are Russian razor blades, and these are great, but just too sharp for a new wet shaver like me.

I started off using feather blades but found them to harsh for my skin. Enter the perma-sharp blades this is the best razor-blade I shaved with period. I have sensitive skin with coarse hair. This blade is so smooth to shave with I can easily do multiply passes and achieve a close shave. I could not do this on the feather blades.
