Your slicer blade should be sharpened at least once a month. This will ensure that your meat cutter continues to produce great results, even after many uses. Sharpener attachments are available in some meat slicer kits. You will need to buy a separate sharpener tool if this is not the case. No matter what, make sure to clean the meat slicer blade before you use it. You can also apply a cooking oil or sharpening oils to the blade's surface and edge. After that, align your blade with the sharpening edge. You will need to position your blade edge as close as possible for most sharpening stones or attachments. Simply sharpen the blade to restore its edge. The blade should appear to have regained its edge. However, you may be able tell by looking at it. You should not oversharpen the meat slicer blade. Too sharp edges can easily be bent or crushed when they are used next.
