Lets go from here..........
Just a thougth 'er 2, if your str8 razor is sharp enough and you are stretching your face as well as you can, then two things come to mind, first the razor angle, if you think about the actual angle of a razor bevel, and just how it would attack the bottom of the wisker itself, you will realise just how shallow[razor flat against the face] the razor should be, eccept of course at the very places that you will need a fairly steep attack as I do just under the nose on the upper lip. Another point is face prep, can not insist just how much hot water and scrubbing the beard needs to be supple enough for a good shave, lots of washing, followed by lots and lots of hot water in the rinse, a good pre shave can be very good for many beards, I use Proraso pre-shave for pre/and post shave use's. A couple of minutes with a very hot and moist towel against the face works wonders for me also. Well ENOUGH of my prattle, this is what seems to work well on MY beard, hope it helps for you.
Have a bloody great G/day' and try to enjoy the
recession as best you can!! tinkersd of SRP!
