## What is Knife Sharpening Log?

Keep a clear record of your stones, blades, and sharpening sessions. Whetlog helps home cooks, sharpeners, and knife collectors remember their tools and the grit progressions they use.

STONE WALL
• Catalog water stones, ceramic stones, diamond plates, natural stones, and strops
• Sort your collection by grit and keep a separate wishlist
• Save maker, model, grit, type, and personal notes

BLADE LOGBOOK
• Keep a card for each kitchen knife or other blade
• Record maker, steel, type, and sharpening history
• See which progression you used last time

SESSION TRACKER
• Log the stones used, in order
• Save duration, result rating, stropping, and notes
• Revisit prior sessions before the next sharpening

LIFETIME UNLOCK
Core cataloging and session logging stay available without an account. A one-time Lifetime purchase unlocks Blade Card sharing and data export. No subscription and no renewal.

PRIVATE BY DESIGN
Your catalog and sharpening history stay on your device. Whetlog is a record-keeping tool, not sharpening instruction or safety guidance. Always follow the instructions supplied with your tools.
