Abstract
A utility knife employs a slide having a cantilevered lever for capturing a blade therein. A leading blade in a reservoir is capturable by the slide using a tooth resiliently affixed to the slide which is positioned to enter a locking hole in the blade. The tooth may be withdrawn from the hole in the blade whereby the blade may be removed for reversal and reinsertion or for discard. When the captured blade is removed, the slide may be returned to the loading position for capturing the next blade from the reservoir. As long as a captured blade is engaged by the tooth, the slide is prevented from returning to the loading position, and the loading blade in the reservoir is prevented from advancing.
