💎 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 most iconic sources within the Kyoto Natural Finishing Stone (Awasedo) tradition,
belonging to the famed Nakayama mountain system.
As Kyoto’s natural whetstone resources continue to diminish, current availability is limited mainly to old stock and private collection releases, making these stones highly sought-after.

2. Identification Features
・Typical 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 affect hardness, slurry formation, and sharpening feel.

3. Sharpening Characteristics
・Generally hard, requiring firm slurry generation to reveal its smooth and lubricated sharpening texture.
・Produces minimal slurry but delivers a clean, crisp, and controlled sharpening sensation.
・Provides an ultra-fine finish around #10,000–#12,000, ideal for final polishing or razor-edge finishing.

4. Rarity & Availability
・Modern production is virtually nonexistent — most are vintage or collector-grade stock.
・Occasionally seen in auctions; careful authentication of stamps, strata, and cracks is recommended.
