How to Stay Sharp

Adam Quality knives are the most important tool for any chef, and keeping your knives sharp is essential. Sharp, well-maintained knives are safer, provide more control, and are incredibly fun to use. While a new knife will arrive sharp, with continued use, even the best knives will eventually go dull.

WHAT IS SHARPENING, ACTUALLY?

A sharp knife’s edge will come to a thin, polished point. Over time with use, this delicate edge will get worn down, exposing a thicker, duller point. When you sharpen a knife, you are physically removing steel from the surface of the knife to re-form a thin, sharp edge. (Note that sharpening is NOT the same as honing!)

What’s the best way to sharpen a knife?

There are a several ways to sharpen knives at home, but we HIGHLY suggest learning how to sharpen using water stones (whetstones). While this method takes a bit of effort to learn, the payoff is well worth it. You’ll get the best edge and remove the least amount of material from your knife if done properly.

Understanding Sharpening Stones

Sharpening stones consist of coarse, abrasive material bound together to form solid stones. As you run your knife along the stone, the abrasive material will cut away microscopic layers of metal. You can see this metal in the dark paste that will form on the stone called the slurry (more on this later). Lower grit stones will remove metal more quickly, and provide a coarser edge. These are great for re-establishing an edge quickly and removing any dents or chips from your blade. As you increase in grit, the stone particles get finer, removing less metal with each pass and helping to create the polished, smooth edge that makes your knife screamingly sharp.

What equipment do you need?

For beginners, we’d recommend starting with a medium grit stone (1000) to remove chips and set a new sharp edge. If you’re up for a little more, a finer stone (6000 or 8000) will help polish your knife to a scary sharp mirror finish. We’d also recommend getting a flattening stone (a ‘stone fixer’) to ensure your sharpening stones perform consistently, though a lower grit stone can also serve a similar function. Lastly, while sharpening stone holders are helpful (and we use them), you can easily just use a damp towel to place your sharpening stones on during use for stability.
