CRKT 8900K Mah Eraser Folder, Black ComboEdge Blade, G10 Handles. Designer Liong Mah uses a bold profile to shape his vision of tactical. The Eraser™ locking liner tactical folding knife is designed and built to perform in your world. Its modified tanto blade wields a strong point for tough piercing into a variety of materials, and the elongated cutting edge can go the distance.

Opening the blade is rapid with use of the Flipper on the spine. Another added feature is the patented LAWKS™ manual safety mechanism so you can secure the blade when open. The robust Eraser™ handle has a slight bend at the fore end to create a more substantial grip form for thrusting. The handle shape also affords a nice blade guard as well as a generous pommel. The machined G10 scales are radius contoured to fill the grip and the full, stainless steel liners create a formidable foundation for tough use.

All in all, the Eraser™ folder is one excellent tactical folder that can take every bit of what you can dish out.
