1. Purpose and Application of Mortising and Ripping

Mortising and ripping are methods of the manual chip-forming woodworking technique. They serve to

- make recesses in the wood,
- prepare surfaces for joining,
- remove adherent material and glue residues.

The purpose of mortising and ripping is

- to manufacture snugly fitting wood joints by shaping the mating surfaces true to dimensions,
- to make recesses for the setting of fittings,
- to shape rough and fine wood surfaces,
- to secure a high surface quality of wood surfaces.

When mortising the tools are driven into the wood by means of a striking tool. Ripping is the finishing of the wood by guiding and pushing the tool with both hands.
