Derby.. For sure. Only tuft that went into the bin after the first use with the first blade..
hmm... sorry, I mean especially Derby extra,but probably some people say Derby including also premium. I have no experience of any Derby, but a few people say Premium is just slightly better than Extra,or almost same worthless.Confusing, isn't it?
If people would say which Derby they didn't like things would be much clearer.
If people dislike Derby Extra then say "Derby Extra", not just "Derby".
Derby Premium and Derby Usta are great blades imho.
