So, this one didn't go according to plan -- the razor doesn't shave very well. Doing a bit more thinking, I think it's bevel was probably made with tape, and when I redid it (without tape), I just didn't 'reach' the cutting edge, so it looks fine under the loupe, but it's not.
So I need to probably get back to a 1000 grit and back up again, to make sure the cutting edge is 'mine'.
In any case, handling seems fine, quite nimble in a way, I think I will like it, once it behaves like a razor
