Remove the Shaft: Gently unscrew the diamond-coated sharpening shaft from the interior of the aluminum handle.
Assemble for Use: Turn the shaft around and screw it onto the opposite end of the handle. This will extend the Ultra-Tek to its full 9-inch length, providing a stable and comfortable grip.
Position the Blade: Hold your knife blade against the diamond-coated shaft. For most knives, aim for an approximate 20-degree angle between the blade's edge and the sharpener. Consistency in this angle is key for effective sharpening.
Perform Sharpening Strokes: Using light to moderate pressure, draw the blade smoothly across the sharpening shaft, moving from the heel (closest to the handle) to the tip of the blade.
Alternate Sides: Repeat the sharpening strokes on the opposite side of the blade. Ensure you perform an even number of strokes on each side to maintain a symmetrical edge.
Check Sharpness: Carefully test the blade's sharpness. If needed, repeat the steps, focusing on light, consistent strokes until the desired sharpness is achieved.
