ABSTRACT:
A rasp tool including a handle member, a cutter member, and a releasable locking mechanism for selectively coupling the handle and cutter members. The locking mechanism includes a locking post on the cutter member and a corresponding post-receiving bore in the handle member. A spring-biased locking key is disposed within a guide bore that intersects the post-receiving bore such that the locking key extends partially into the post-receiving bore. As the locking post is axially introduced into the post-receiving bore, the locking post contacts the locking key and causes it to retract until the locking post is fully received within the bore, at which point the spring-biased locking key engages a transverse notch in the locking post, thereby preventing axial removal of the post from the bore. The locking key is disengaged from the locking post by a manually-actuable trigger coupled to the locking key.
