This part is always a bit nerve wracking. First i have to drill guide holes. Keeping every single one centered exactly where they need to be is challenging to begin with. If one is slightly off center, that will ruin everything.
Then i need to drill the outer diameter of the stones over the guide holes and make sure the drill does not go off center. This needs to be done on both sides.
And then drilling through with a slightly smaller drill to expand the hole as much as possible without destroying the remaining ridge that will hold the stone.
This can be stressful, especially considering this is a tamahagane razor.
Still, it worked out and this is going to be an awesome razor.
