I used the natural shape of the grinding wheel, that way you are keeping the hollow uniform. This way, when you are doing a final grind on the hollow you will be able to just add more pressure at the cutting edge and the hollow will be uniform. When you start final grinding and polishing, all of your mistakes start to glare. Try to get everything perfect before HT, this is where the handwork comes in.

It also looks like you took the hollow grinding down the tang of the razor. This will not work with scales, the tang needs to have parallel sides. They can taper towards the tail, but the sides must be straight.

Don't forget that pivot hole...
