Key Systems Tamper-Proof Key Rings® - Tools

Closer The closing tool's black body has five shallow grooves and one deep trench. At its tip is a small black knob used to adjust the tension on the silver swing arm that pulls the ring closed and locks it in place.  
Crimper The gold crimper's black handle lifts to reveal three small rollers with rounded ridges that squeeze the connection where the two ends of the ring meet.  
Cutter The red cutting tool operates just like the crimper, with the same black handle, except here the three rollers have sharp ridges for cutting through the rings.
