This is the Blade Tech Diamond Taper Steel™ with friction fit sheath. Diamond coated steel, plastic handle and sheath and fishing hook sharpening groove. The Blade Tech Diamond Taper Steel™ will practically sharpen any knife or tool along with other items such as strap cutters, serrated blades, hoof knives, spoon carving knives and fishing hooks. When sharpening strap cutters, serrated blades, hoof knives & spoon carving knives, simply use the Blade Tech® Diamond Taper Steel in a forward, twisting motion away from the blade ensuring you go no further along the steel than the diameter at which it is matched to the size of the blade or serration. Once this is done and if the blade has a bevel on both sides then turn the blade over and repeat the process. If the blade only has a bevel on one side then wipe the small burr off the back side of the blade with one or two smooth light strokes. Fishing hooks are sharpened using the groove in the side of the steel . The Blade Tech Diamond Taper Steel™ can also be used on most other blades such as knives and tools if used in the same way as with a large, chefs type steel. The Blade Tech Diamond Taper Steel™ is supplied with a plastic friction fit sheath to protect the sharpener when not in use. The sheath also has a pocket clip so no matter where you’re going, you can take your Blade Tech Diamond Taper Steel™ with you. As with all Blade Tech products, the Diamond Taper Steel is included with a 30 day satisfactory guarantee and Blade Tech™'s Evermore Warranty which guarantees against defects due to workmanship or materials.
