Has anyone here had any experience with DORCO Blades? I got two packs in my "les then impressive"sampler pack, and just used one last night. So far I've only used Derby and ASTRA. I wasn't expecting much from the DORCO blade but I'm presently surprised. In my approximately 1 month of de shaving it has been the best shave yet. Sharp enough to not be tuggy, but dull enough to let me do the needed touch ups without ANY irritation. Why hasn't I heard anything about these blades here before? From my lurking around here, I was pretty much settled that I would end up with ASTRA or Derby as my go to. ..... but I'm not so sure anymore. Thoughts? Opinions? Also, the ones I used say "new 301"on them and the second pack I have say 300. Any difference?
