ABSTRACT:
A reciprocating cutting tool includes a shank for mounting in a pneumatic hammer, a blade holder assembly connected to the shank and a blade clamped in the blade holder assembly. The blade holder assembly includes a base member and a retainer member which are clamped together. A blade receiver is formed between the base and retainer members. The base member includes a recess and the retainer member includes a shoulder which is received in the base member recess for abutment by a fixed end of the blade. A method of removing adhesively-attached ornamentation from a vehicle body panel includes the steps of providing a blade holder assembly with base and retainer members, providing a blade with a proximate end and a distal end having a sharpened distal cutting edge, clamping the base and retainer members together with the blade proximate end therebetween, providing the retainer member with a shoulder, abutting the blade proximate end against the shoulder, reciprocating the blade holder assembly and advancing the blade cutting edge through adhesive between the ornamentation and the vehicle body panel.
