Work Sharp MK2 Professional Electric Knife and Tool Sharpener - Adjustable Tool and Knife Sharpening System

The Work Sharp MK2 Professional Electric Sharpener differs from traditional whetstones by using flexible abrasive belts instead of stone surfaces. This design eliminates the need for typical grit levels or water/oil lubrication and features a medium grit belt that adapts to various blade shapes, making it versatile for knives and many outdoor tools. Its compact size and included edge guide facilitate easier and more consistent sharpening, especially for those without experience using whetstones.

Equipped with a two-speed motor, the sharpener offers extra power for heavy-duty tasks like sharpening lawnmower blades or axes, which is an added advantage. However, being a plastic-bodied electric device rather than a manual stone, it may lack the precision that some users expect from traditional whetstone sharpening. Additionally, the use of belts may be less suitable for users seeking exact grit progression or fine polishing.

The device's ease of use, capability to handle serrated and specialty blades, and a solid 3-year warranty make it an excellent choice for those wanting a quick, safe, and all-in-one sharpening tool without the hassle of water or oil maintenance. If you are looking for a straightforward way to keep a wide range of blades sharp with minimal effort, this sharpener is well-suited. Those who prefer the hands-on control provided by classic whetstones might find it less ideal.

Buying Guide for the Best Whetstone Knife Sharpener

Choosing the right whetstone knife sharpener is essential for maintaining the sharpness and longevity of your knives. A good whetstone can help you achieve a razor-sharp edge, making your cutting tasks easier and safer. When selecting a whetstone, consider the following key specifications to ensure you pick the best fit for your needs.
Grit LevelGrit level refers to the coarseness or fineness of the whetstone's surface. It is important because different grit levels are used for different stages of sharpening. Lower grit numbers (200-600) are coarse and used for repairing damaged edges or reshaping the blade. Medium grit (800-2000) is used for sharpening and maintaining a general edge. Higher grit (3000-8000) is fine and used for polishing and refining the edge to a razor-sharp finish. Choose a grit level based on the condition of your knives and the level of sharpness you desire.
Stone MaterialWhetstones can be made from various materials such as natural stone, synthetic stone, or diamond. Natural stones are traditional and provide a unique sharpening experience but may wear down faster. Synthetic stones are more consistent in quality and durability. Diamond stones are the hardest and most durable, offering fast sharpening but can be more expensive. Consider the material based on your sharpening frequency and preference for durability and maintenance.
SizeThe size of the whetstone is important for ease of use and compatibility with your knives. Larger stones (around 8 inches or more) provide a bigger surface area, making it easier to sharpen larger knives and achieve consistent results. Smaller stones are more portable and can be suitable for smaller knives or travel. Choose a size that matches the types of knives you have and your sharpening setup.
Base or HolderA base or holder provides stability while sharpening, preventing the stone from slipping and ensuring safety. Some whetstones come with a non-slip base or a holder, while others may require you to purchase one separately. A stable base is crucial for effective and safe sharpening, so consider this feature based on your sharpening environment and preference for convenience.
Water vs. Oil StonesWhetstones can be categorized into water stones and oil stones based on the lubricant used during sharpening. Water stones use water, making them easier to clean and more convenient for quick sharpening sessions. Oil stones use oil, which can provide a smoother sharpening experience but may require more maintenance and cleanup. Choose between water and oil stones based on your preference for ease of use and maintenance.
