These are currently my go to blades.

I get basically zero irritation on my scalp when I use these, although I don’t get quite as many uses out of them as I would other blades. You can definitely tell when it’s time to change the blade, as it starts to tug really badly.

Feather blades are very sharp and you’ll get a lot of uses out of them, but that sharpness could also mean cuts and irritation if your technique isn’t solid yet.
