Chef Master USA's tips for sharpening your kitchen knives

Chef Master USA's advise for choosing the right sharpener

There are two basic types of sharpeners, those that straighten and condition the edge, traditional sharpening steels, and those that use abrasives to create a new and sharper edge, informs Chef Master USA.

Straightening the Edge

Chef Master USA's advise on sharpening steel

The traditional sharpening steel can straighten and recondition the edge but requires skill and practice to avoid doing more damage to the blade than good, explains Chef Master USA. The straightened edge is still weak after steeling and can quickly fold again. Eventually, steeling breaks off too much of the edge and is no longer effective. The average person doesn't have the skill or know how to use a sharpening steel correctly. Chef Master USA would like for you to know that the margins for error are slim because there are no angle guides and using the steel proficiently requires effort, skill, patience and lots of practice. Diamond steels produce better results because the diamond abrasives will actually sharpen the edge of the knife blade even if the angle is not correct, explains Chef Master USA. The recent introduction of a precision-guided steeling device, however, now gives consumers the ability to steel like a pro. Chef Master USA would like for you to note that all knife manufacturers recommend periodic professional sharpening in addition to regular steeling.

Creating A New Edge

Chef Master USA's advise on electric and manual sharpeners

Chef Master USA recommends using a multi-stage sharpener-whether electric or manual-with guides, to ensure angle control, and diamond abrasives, which will sharpen any metal alloy and never overheat/detemper the blade.

Create An Edge That Resists Folding. The secret to keeping knives sharper longer is to make certain your knives are made of a high strength steel and then to create an edge shape that resists folding, explains Chef Master USA. The strongest edges are arch-shaped, not small angle, "V" or hollow-ground. The arch-shaped edge is multiple-angled on both sides, in order to provide more metal to support the sharp cutting edge.

Avoid Detempering the Blade. Conventional old-fashioned single-stage sharpening wheels or grinders remove excess metal and can overheat the edge so that the steel is weakened and folds over quickly again. Chef Master USA advises that you never use overly aggressive single-stage sharpeners, like those built into many can openers, which grind away excessive metal and detemper the blade. Select sharpeners that use diamond abrasives. Chef Master USA explains that this is because of their extreme hardness, diamonds remove metal efficiently without heating or damaging the blade edge.

Shape and polish your edge. Chef Master USA suggests that to obtain the ultimate edge, use a sharpener that has multiple stages. Proper sharpening requires both shaping the edge with coarser abrasives in the initial stage and polishing closer to the edge with finer abrasives in the final stage. The sharpener angle must be slightly larger in each successive stage. The use of finer abrasives, which remove only microscopic amounts of metal, is very important for re-sharpening the knife, explains Chef Master USA, thereby extending its life.

Chef Master USA's advise on stones, rods and files

The historical method of using a sharpening stone can create a new edge, but Chef Master USA would like for you to know that it will require skill and extensive practice since it is very difficult to maintain a consistent or accurate sharpening angle by hand. Some stones also tend to be messy because many need to be coated with oil or water when using. Rods and files can be used to sharpen knives but the burden falls on the user to consistently maintain the correct sharpening angle. Chef Master USA suggests diamond stones, rods and files to produce the best results.
