Brand new Leatherman Surge, nice in all aspects except the tool I bought it for, the scissors, loosened up after less than two minutes (5-or 6 Cuts on lightweight waxed thread.) Is there a tool to tighten the screw I have to purchase, or does it have to be sent back to the factory? I am getting pretty tired of sending Leathermen back to the factory. First it was because the Plier jaw snapped in half with normal use, (supertool) second because the blade snapped while cutting rope, (Early Wave) and now this.
