Electric handheld knife sharpeners are typically designed and marketed for use on kitchen knives and other small, handheld blades. While some electric sharpeners may have adjustable settings to accommodate different blade angles, they are generally not suitable for larger tools like axes or machetes.
Axes and machetes have much thicker and larger blades compared to kitchen knives, and they require a different sharpening approach to achieve the appropriate edge. Using an electric handheld knife sharpener on an axe or machete could lead to uneven sharpening, potential damage to the sharpener, or an ineffective edge on the tool.
For sharpening axes and machetes, you should use tools specifically designed for larger blades. Some options include:
Sharpening Stones: Whetstones or oil stones are traditional sharpening tools that can work well for larger blades. They come in different grit levels, allowing you to refine the edge gradually.
File: A metal file can be used for coarse sharpening on axes and machetes. It's essential to match the file's coarseness to the condition of the blade.
Bench Grinder: A bench grinder with appropriate grinding wheels can be used for heavy-duty sharpening of axes and machetes. However, using a grinder requires caution and practice, as it can remove material quickly.
Guided Sharpening Systems: Some sharpening systems come with guides that help maintain the proper angle during sharpening. These can be useful for achieving consistent results.
Remember, when sharpening larger blades like axes and machetes, safety is paramount. Always wear appropriate safety gear, such as gloves and eye protection, and ensure the blade is securely mounted or held during the sharpening process. If you are uncertain about sharpening larger blades yourself, consider seeking assistance from a professional or someone experienced in sharpening such tools.
