Thats a good razor you have there, and you dont need another one. Wanting another one is a different story though..!

Feather and DE blades are coated in teflon which gives them that over-sharp feeling that some people like or dont like. This adds to the glide of the blade.

Its certainly possible to get a straight razor to shave as well as a DE blade and in fact I get better shaves with my straights than I do with my DE. They are different beasts, with different bevel angles, but I prefer the straight razor to the DE.

You can try strop pastes if you dont want to send the razor off to be honed, as Joed suggested, or get yourself a barber hone for use in touch ups. You can get barber hones on eBay.

Good luck and keep us posted!
