Tool Care & Sharpening
Sharp tools cut more predictably and require less force. Regular light maintenance is easier than restoring a badly damaged edge, and it helps protect both the tool and the workpiece.
Before first precision use
Inspect the back and cutting edge. For a conventional bench chisel, prepare and polish the working area of the back so it is flat at the cutting edge, then hone the bevel. Remove the factory corrosion coating only where sharpening requires it.
Bench-chisel angles
KIRSCHEN bench chisels are factory-ground at approximately 25°. For routine honing, the manufacturer recommends a small secondary bevel around 28°–30°. Harder woods can benefit from a steeper edge, but the appropriate geometry varies by tool and use; always check the specifications on the product page.
A practical sharpening sequence
- Use a secure, non-slip sharpening surface and follow the stone maker's instructions.
- Flatten the working area of the back when necessary, using the full stone surface to promote even wear.
- Hone the bevel at a consistent angle. A honing guide can improve repeatability.
- Progress to finer stones and remove the burr from the back between stages.
- Clean the blade and stone as you work so loose abrasive does not contaminate the next grit.
Preventing rust and damage
- Wipe the blade clean and dry after use.
- Apply a light film of suitable oil before storage, especially after removing the factory coating.
- Fit the edge protector and store tools so cutting edges cannot strike each other.
- Do not use a chisel as a pry bar, and use striking tools only with handles designed for that purpose.
