The Blademedic Knife Sharpener is the first responder for field repairs on all types of knife blades. It's like having an entire sharpening kit right in your pocket! The sharpener is able to tackle regular or serrated blades, gut hooks, hunting knives, fishing knives - just about any knife you put in front of it. Three or four strokes on the tungsten carbide will restore your extra dull blade and the ceramic sharpening rods polish it to a finished razor's edge. The serrated sharpener is designed to get inside even the smallest blade serrations. Then, the diamond tapered rod can be used for fast reconditioning and maintenance. This will be the best money you've ever spent on a blade sharpener. You won't need any other sharpeners!
