Abstract
14,606. Hill, G. L. June 30. Chisels for mortising have their cutting-edges formed with a central tooth 12 and lateral teeth 6, the blade having turned-up sides 4, which may be notched at their lower ends. A sliding block 13 has a handle 16 and is used for removing shavings from the tool and also as a protecting-piece for the cutting-edge.
