The Smith's CCKS 2-Step Knife Sharpener is a fast and effective tool for sharpening knives. It features crossed carbide blades for rough setting and crossed ceramic rods for a sharp edge. The sharpener has a fixed 46-degree sharpening angle (23 degrees per side), which provides excellent results for regular pocket knives. While it may not be suitable for sharpening scissors or ceramic knives, it is a great option for achieving a sharp edge quickly.
