One of the most common causes of less than perfect work is a blunt blade. Instead of cutting cleanly, it drags. So it’s essential to always work with a sharp edge, and whilst OLFA Excel Black snap-off blades are the sharpest on the market, they will still become blunt and need frequent snapping. The OLFA DC-5 Advanced Blade Disposal Holster hooks onto your tool belt, so it’s on you at all times. Open the front flap and insert your knife (9mm, 12.5mm or 18mm) into the slot with a single blunt segment exposed, pull towards yourself and the snapped piece is automatically stored safely inside.
