Abstract
Abstract A holder of improved construction for mounting a saber saw blade on a drive means for reciprocation. The holder includes means defining a slot for receiving the blade, and means coupled with the support means for retaining the blade in the slot and for preventing movement of the blade relative to the support when the support and blade are reciprocating under the influence of the drive means. The holding means in several embodiments includes cam members which are received in notches in respective blades. Other embodiments relate to the formation of blade-receiving slots by moving wall means into proximity with recesses in side faces of elongated members.
