Heljestrand MK 10 on the nakayama maruka. On my last shave with this razor I hit the edge to the sink and put a chip in the blade. Took the chip out on the 1k then used a botan-meirjo on a shobudani. Final touches today with Koma and Tomo. Thought I would try honing with stone in the base vs my hand and get zen with it. cheers all
