A large maruka nakayama with hatanaka box. There are a lot of fake maruka stones floating around, and since I ordered this from japan and not directly from hatanaka, there’s no guarantee that it’s genuine, but I am also not intentionally selling any fakes, and this stone is not adorned with gobs of fresh ink tastelessly blobbed all over it. It is an uncommonly uniform stone. I’m not sure how old it is, and don’t know the origin of the small crack in the side except that it doesn’t affect honing razors and is not open or unstable.
Prior owner affixed the stone to a base, and great things don’t always happen when you separate a stone from a base (it often results in parts being left on the base with voids in the base of a stone – or worse) so I have left it alone.
It is not tolerant of tools (like some very hard stones, the surface sustains scratching and requires too much care to avoid that occurring), but it is an excellent razor finisher both using it as a base stone with its own slurry (diamond hone generated – it will not otherwise release slurry with razors), or with nagura. Too fine for most knife use, and as with tools, pointy small blades will lead to surface scratching of the stone.
About my comments per use: • Razors: I hone a razor and shave a full shave with it before I comment about usefulness with a razor. I have used just about every common razor stone. If the shave is not both smooth and sharp, then I will not call a stone suitable for razors. • Tools: In order to be recommended for tools, a stone has to cut reasonably fast and not fracture at the surface (shoubu stones are notorious for getting scratched up by tools, as are many ultra hard stones like ozuku). If I describe a stone as being good for tools, it either exhibits none of this at all (after testing with a wrought iron and white steel wide chisel), or only a small amount when the user has bad technique and allows corners of tools to dig at stones and leave lines. All but the very hardest stones will self slurry with Japanese laminated tools. Some more quickly than others. A stone with good surface toughness and the tendency to self slurry with laminated steel (particularly the wrought iron part) but not with hard steel or razors is just about ideal for practical use. • Knives: Knives are the least particular to hone unless you’re looking for a specific finish. If you will be sharpening small pointy knives like kiridashi, then you will need to rely on the tool rating to determine if the stones are OK.
All of the stones that I list are even gritted with no toxic particles unless otherwise mentioned. Cracks or mineral lines are superficial unless mentioned – if one seems a threat to separate later, I will specifically mention that and the price of the stone will reflect it.
I am careful about how I describe these stones, and if you find you get a stone that is not accurately described, you can return it for a refund. I am not a dealer, per se, and list stones for what I think they’re worth at market less 25%. Sometimes that’s more than I paid, and sometimes it’s less. I deal in razors and stones to support my collection, not to make a living or any set amount of money.
All of my stones come directly from japan unless otherwise mentioned.
