Abstract
A clamp for a reciprocatory tool blade is disclosed having a spring loaded roller constrained in an inclined blade accommodating cavity which so effectively forces the roller into clamping relation against a tool blade shank that no special blade shank configuration is required and manual shift of the roller against the spring load provides for ready removal of the tool blade.
