So everyone is confident that blades are only ever blunted by whiskers and not the effects of corrosion? Fair dues.
Perhaps one of the authorities on shaving and stuff and things from this forum should email the inventor, in a Theo Paphitis way, saying his idea is a non-starter.
Then again, there's money in this shaving malarkey so perhaps it'll go the way of the razorpit and keep its inventor in cashmere socks, sea island cotton underpants, seal fur slippers and cuban cigars for the rest of his life.
Good luck to him.
Might even bung him a few quid myself as my money is making me bugger all in ISAs.
