How it works
For anyone who sharpens on water stones at home.
-
Add your blades
Kitchen gyuto, santoku, EDC folder, or hunting knife — steel, angle, and days since the last sharpening in one bench.
-
Log each session
Date, grit progression, angle, passes per side, and a sharpness rating after the edge test — touch-up or full progression.
-
Review & remind
See which stones worked best in the journal and set edge-check reminders so you test the blade before it feels dull.
