Knife Sharpening and Care

Koi Knives Head of Sharpening, Joao Sundfeld, takes us through sharpening chef knives at home with whetstones.

Lots of great tips and know-how, so watch the master on the tools. Since creating this video, we have launched our own set of high quality and durable whetstones, check them out here

Sharpening your own knives at home can be both daunting and extremely rewarding. Knowing how to care for your knife will extend its life indefinitely, and will also put you in the drivers seat for controlling the quality of your cutting edge. A skill that takes a few times to learn, and a lifetime to master, like all great things.

Professional Tune-Ups

Every few years, we also suggest a professional tune-up for each of your knives. To correct the bevel, control the cutting edge geometry, and to oil and polish the entire knife. Here is Joao once more, to show you how we sharpen/shape/polish your knives when you bring them in to us.

His bit of kit is total overkill at home, but great to show the level of dedication and quality that can be achieved with the right tools. Not to mention that your knives are in safe hands with this master.
