my name is Steve and I'm trying to get started in straight razor shaving. I spent several weeks trying to soak up info from the net about this hobby. I have a new Dovo basic carbon steel 5/8 model on order as well as a Norton 4000/8000 whetstone, and a leather stop. I've been reading about lapping stones and I'm currious if I really need one? The Shapton GDLP is very expensive, and I've noticed that some people use some of the DMT products as well that are not quite as expensive for the same purpose. I would appreciate any advice that you could please give me in regards to lapping products.
