ABSTRACT:
A cutter knife for locking a slider by the engagement between a leaf spring member and an engaging notch of a cutter main body. The leaf spring member has a flat spring section; and a U-shaped locking section projecting therefrom at a right angle therewith. A pair of flat portions of the locking section engage the engaging surfaces of the engaging notch. Consequently, the slider is locked. The operating member moves with respect to a slider main body, thus pressing the locking section downward. As a result, the slider is unlocked.
