As the Cimeter knife is exceptionally long, you may wish to use a sharpening stone as an alternative to an electric/automatic knife sharpener. This will reshape the blade and ensure a quality cut, but you should also have a honing steel handy to maintain the edge throughout your work with more significant cuts. Just be sure to clean the blade with a microfiber cloth in case of any leftover materials. Other types of knives can be sharpened with a few draws, but this one will take a bit more work because of the length and curvature.
