How to use

Secure the workpiece before starting to ensure safe and accurate cuts. Use the chisel bevel side up for controlled paring and thin shaving cuts, and bevel side down when chopping into joints or removing larger amounts of waste. For chopping mortises or heavy removal, strike the handle with an appropriate mallet; for fine finishing and trimming use only hand pressure. Regularly hone the cutting edge to maintain sharpness and inspect the handle for signs of wear or looseness before each use.

Usage recommendations

Maintain the cutting edge by honing with a sharpening stone or strop before and after use. Match the chisel width to the joint or detail being worked on to achieve cleaner results. Store the chisel in a dry place with edge protection to prevent damage and ensure safe handling.
