Although the WSKTS-KO is a bit expensive compared to the standard work sharp’s edition, you get a stronger motor, adjustable speed, wider belts and a greater range of angle adjustment. Being a belt-based system, the edge produced when knives are sharpened will be the way knives come from the factory.

Let’s face it, the Work Sharp WSKTS-KO Sharpener is quite expensive but at the same time saves your precious time. I have mentioned that since I have personally used and found that it is one of the fastest ways to get your edged tools as sharp as you need them to be.


Not only is the Work Sharp WSKTS-KO Sharpener capable of sharpening every kind of knife, but it is also expandable with optional attachments. Ideally, specialty belts are also available for specific sharpening needs, including ceramic knives.

Precise angle

The Work Sharp WSKTS-KO has a special design feature that actually makes cutting safer and easier. What I like about this Sharpener is that your knives are sharpened at the same angle each and every time, making re-sharpening so quick you will never have to work with a blunt knife again.
