NT CUTTER® L-500GRP is a very heavy duty handle, the L-500GRP comes complete with a 7 point snap off 45˚ blade.
 
Made from solid steel with an auto lock system meaning no matter the amount of pressure you apply, the blade will never return back.
 
The NT CUTTER® L-500GRP also features it’s own blade snap off tool, when a blade becomes dull, simply pull the snap off tool from the back, break the blade off to reveal a new sharp point.
