Determine if your tool needs sharpening. One easy way to decide if your tool is becoming dull is to see if it reflects light well. Shine is an indication of wear. You can also gently scrape a fingernail on a blade and see if it shaves off a sliver; if it does not, the blade is dull. Touch is not necessarily a good way to determine if a blade is sharp, as a dull carbide tool may still feel sharp.

Find a professional sharpening service. Sharpening carbide is not recommended for non-professionals, as it requires skill and specific sharpening machinery. Imprecise sharpening can ruin a tool, and a professional can restore a blade to like-new condition.

If you are interested in learning how to sharpen blades yourself, it is recommended that you locate a teacher.

Carbide tools require diamond for sharpening, due to their hardness. Wet grinding using an abrasive wheel on an automatic grinder is a very precise method of sharpening. It is also possible to sharpen a tool by using a diamond lap, but this is very imprecise and time-consuming.
