CRKT designed the ABC E.R. Knife to fill the needs of scuba divers, whitewater paddlers, and rescue professionals. Use the serrated edge to quickly cut through webbing, cords, or fishing line in dangerous entanglement situations. The razor sharp edge is ideally suited to finer tasks, like cutting your bagel in half at lunch. The E.R. knifes blunt tip wont pierce air compartments if dropped, and provides a measure of extra safety in rescue scenarios. Columbia River Knife and Tool gave the ABC E.R. a skeletonized high-carbon blade with a bright brushed finish for excellent strength and corrosion resistance. The included Zytel sheaths dual attachment panels and stainless steel spring clip allows attachment to your belt, dive straps, or pfd.
