Know before you buy
Yes, the Model 120 is designed to sharpen both straight-edge and serrated blades. It uses the polishing stage to effectively hone the serrated teeth without damaging them.
This model is specifically engineered for European and Western-style knives, which typically have a 20-degree edge angle. It is not recommended for Japanese knives, which usually require a steeper 15-degree angle.
No, this is a dry sharpening system. The 100% diamond abrasives are designed to work effectively without the need for any honing oils or water, keeping the process clean and simple.
The first two stages use diamond abrasives to repair damaged edges and create a sharp new profile. The third stage uses a flexible stropping disk to polish the edge, resulting in a razor-sharp, burr-free finish.
The sharpening angle is fixed at 20 degrees using precision elastomeric guides. This ensures a consistent, factory-quality edge every time you sharpen your knives.
The unit is very low-maintenance. Because it uses diamond abrasives and no liquids, you simply need to keep the exterior clean and occasionally clear out any metal shavings that may accumulate inside the housing.
