Electric knife sharpener with battery 1200mAh | Kalsten

Dull blades cost you more time and effort than cutting itself.

Who doesn’t know that: the knife slips, the cut isn't right, and sharpening with a whetstone takes forever. With this compact electric knife sharpener, you can bring any blade back into shape in minutes – whether in the kitchen, while camping, or in the workshop. The 1200mAh battery charges via USB and lasts through multiple sharpening sessions without the need to hunt for batteries. The result: clean-cutting knives and scissors whenever you need them. 

Advantages

• No more dull knives for your next use: Coarse and fine sharpening stones, as well as a special scissors mode, bring any blade quickly and reliably to the desired sharpening level – without long practice or expensive professional sharpening.
• No more searching for annoying cables: The built-in 1200mAh battery charges via a standard USB cable – you use the same cable as for your smartphone and save the hassle of buying or changing batteries.
• No slipping or sliding while sharpening: The non-slip base keeps the device securely in place, allowing you to focus completely on the blade – without fear of uncontrolled movements.

Application

1. Charging: Connect the USB charging cable and fully charge the battery before using the knife sharpener for the first time.

Pro tip: Always start with the coarse sharpening stone for very dull knives, then switch to the fine mode – this way, you achieve the best cutting edge in the shortest time without unnecessarily stressing the blade.
