As I only had 3 knives I took them into Jon at his factory, where he completed the sharpening while I waited. Took about 15 minutes. The cost was very reasonable. I was fascinated to see all the other samples of his work; custom handles and blade etching. Jon also showed me the correct way to use a sharpening steel to ensure I get the best performance and longevity of the - newly - sharpened edges.
Definitely recommend you bring your knives to Jon.

Approximate cost: $30
