SharpiWave gave new life to my 5-year-old kitchen knives in literally ten seconds. The USB recharging is brilliantly convenient and the fine polishing wheel is sublime.

I used to dread using whetstones because I always scratched my blades. This compact sharpener makes it effortless. The blue lights and dual gears work a treat!

Took it on a camping holiday and sharpened all our utility and slicing knives off a standard power bank. Super lightweight, powerful, and remarkably quiet. Highly recommended buy!
