💎 京都加藤礦山天然砥石 — 簡介

一、礦山與身分
加藤礦山為京都天然仕上砥石體系中極具代表性的一支，
屬於「中山（Nakayama）」產地系統之一。
隨著京都名砥資源日益枯竭，現今多為舊藏或庫存品釋出，流通極少。

二、識別要素
・印章：常見「正本山」「中山」「丸𠮷／マルカ」「加藤家星印」等章紋。
・層系：如 Suita、Tomae、Asagi 等，會直接影響硬度、出泥性與研感。

三、研磨特性（手感與性能）
・通常偏硬，需要較強起泥以發揮潤滑研感。
・出泥性略低，研磨時「乾淨俐落」，拋光階段能呈現極細緻刃口。
・研磨能力常標示於 #10,000～#12,000，適合作最終仕上用途。

四、稀缺性與流通狀況
・現今產量極少，多屬舊礦庫存或收藏釋出。
・拍賣市場偶有流通，但需謹慎鑑別章印、層次與裂紋。

💎 Kyoto Kato Mine Natural Whetstone — Overview

1. Origin & Identity
Kato Mine is one of the representative sources within the Kyoto Natural Finishing Stone (Awasedo) lineage,
classified under the prestigious Nakayama mountain system.
As natural Kyoto stones have become increasingly scarce, most pieces in circulation today come from old stock or private collections, making them highly limited.

2. Identification Features
・Common stamps include: 「正本山」「中山」「丸𠮷／マルカ」「加藤家星印」.
・Layer types such as Suita, Tomae, and Asagi determine hardness, slurry behavior, and polishing feel.

3. Sharpening Characteristics
・Generally on the harder side — requires good slurry generation for smooth sharpening.
・Produces a clean, refined feedback with controlled abrasion and minimal stone wear.
・Delivers a mirror-like, ultra-fine finish rated around #10,000–#12,000, ideal for final-stage honing.

4. Rarity & Market Availability
・Production is now extremely limited — most available stones are from discontinued veins or old stock.
・Occasionally appear in auctions; authentication of stamps, strata, and cracks is essential.
