Speed and consistency are your best friends to sharpen efficiently. Lap often and your stone will cut.
The NL-5 lapping plate is designed to flatten all whetstones from 35μm to 0.5μm (400 grit to 30,000 grit range).
The NL-5 is a traditional plated design. However, unlike standard designs, the NL-5's surface is a series of raised diamond coated structures. It is the edges of these raised diamond structures that are doing the heavy work.
The NL-5 features the star and hexagon pattern maximizing the number of working edges. This increases the number of edge-material contact points.
This plate is not intended for sintered ceramics or diamond resin stones, such as Cerax.
