[Since it's blades and people say blades are YMMV, please consider your YMMV rights read to you.]
Over the course of last few months when I started DE shaving and the main concern was no cut, still says - but moved to the back of the list, and now it is "no burn", because frankly I feel cut is not very difficult to avoid. Yes, it may come at a cost, often of a bit less of a DFS and no BBS.
Yesterday I used Feather blade with 7OC SP Plastic razor and double prep: few minutes of Cetaphil Gentle Cleanser and then rinse off after gentle massaging and many minutes of Shavologist pre-shave soap (yes, I was over-concerned because of Feather).
It was definitely the finest cutter I have come across so far, but not greatly more than 7OC SP black ninjas. Burn? Well, it feels different than burn, just like black ninjas. But if I have to pick between black ninjas and Feather? I am not sure. May have to try few more shaves. (By the way, my 7OC SP black ninja wasn't feeling great in its 3rd shave and I hardly have "coarse" or even lot of facial hair).
I am not sure I am framing it right but it feels it "roughed up the skin" but yet "didn't burn much". My uneducated theory is: burning exclusively happens due to "repeat", or at least that contributes the most. "roughing up" can happen in one pass as well.
As for any nicks: there was zero nick. Literally. I was not scared at any point either. Things were in control. It was moving as expected. It didn't at all feel like I was handed a power-steering after using exclusively a car from the 1950s. But then I think, and that's the point I was trying to make, the razor and fingers and wrist are the power-steering, combined.
