I've just tried out two different razors. One is a Tuckmar-Hammond-Welt RUF 42 it has more stamping on it but I'll stop there. It's German and hollow ground but a lot. I guess you would say it's Half hollow maybe. Then on the other side of my mug I used a Boker 6/8 King Kutter. very hollow ground. both are very Sharpe. The difference is the Tuckmar is heavier. And with the added weight it shaved smoother. Both were used at the approximate angle to the face. with my hands there's really no adjustments. I guess what I'm trying to say is usually I'm a heavy Sheffield person. now it looks like any heavy Sharpe blade will work. just goes to show you that you never Know. (A friend once told me he had many many favorite razors now I know what he ment)
