I get bad irritation whenever I put on a new blade. I do not have any corks or styrofoam is there another material I can use which will not significantly damage the integrity of the blades?
don't have any in the house right now. I want to change blade but always get Irration on the first shave on a new blade. Was wondering if maybe cardboard or leather?
Try palm stropping the blade and see if that takes care of the initial roughness. I have had some success doing this with single edge blades which I always find a bit too aggressive when new.
I've heard of people stropping on jeans or towels or newspaper. I'd probably try some pieces of washable, cheap cloth or a towel you don't care about. The idea of palm stropping strikes me as another way to get nicked or cut (I have never tried it, though).
Before reading your post, my temptation was to post "Nothing!" in answer to your question. But that wouldn't have been very helpful. So I put it down here.
