How have we got to post #7 without mention of Jewel ??!
I think I'd get a closer shave by smashing a raw egg on my face and hoping bits of the shell scraped past my stubble. It's worth a go. Better than standing there, slapping on lather repeatedly, frantically chiseling away in vain, razor in one hand and a curious look on my face as my fingers rub over my cheeks in search of smoothly shaved skin.
7 O'Clock Yellow and Black. Neither suited me for whatever reason. Gave me an uncomfortable shave with uncomfortable results.
Derby Extra.
Just not sharp and get irritation from trying too hard to get results other blades give easily.
Derby, along with Bic, Merkur and Shark are some blades that I'm not even remotely interested in trying based purely on the amount of negative comments I've seen on them. Some blades are Marmite blades, one man's meat is another man's poison, I'll try those, but if a blade is virtually unanimously declared to be crap then I'll stay well away from it
