I've got a cheap WS razor (black plastic one in yellow blister pack) which is apparently pretty good.
I've tried these blades (which are absolutely terrible) Then tried the wilkinson swords (the ones that came with the razor, and also the ones that come from a cardboard tube in individual cellophane packets).
As far as I can tell, both WS are both the same, and they are just no good. I've used them for the past month or so, and they make a noise like pulling velcro when I do my neck and really pull bad, my cheeks are not as bad but I still get a fair amount of stubble after several passes.
Today I decided to use my Wilkinson sword quattro on my neck/chin and it glided really well and left my neck/chin BBS, I never remember it being so good.
I think I am using the correct angle, I never use a blade for more than 3 shaves, so I guess I need to get a blade sample pack (or new razor?). Will changing to a Merkur HD make as much (or more?) difference than just getting different blades?
