Improper use of the knife can lead to a dull edge or a damaged blade. The uses mentioned in the section above are only a few of the common improper uses. However, cutting on the wrong surface can also cause damage to your knife. Hard surfaces such as a metal table, glass, marble or stone can quickly dull a sharp blade and should never be used as a cutting surface. It is always better to use a proper cutting board (wood or plastic) or to choose a soft surface to cut on.

A screwdriver, or a chisel (despite the grind), or a pry-bar, or a bottle/can opener. Your knife also shouldn't be used to cut through metal such as soda/beer cans, food cans, wire etc. There are specific tools for these tasks that are better suited and won't be damaged in the process. It doesn't hurt to carry a multi-tool such as a small Swiss Army knife or a Leatherman to tackle tasks your knife shouldn't be doing.
