The Nano-Hone NL-4 Lapping Plate is designed to flatten waterstones from 110μm to 10μm (120grit to 1500grit). Click here for Grit Micron Comparison Chart

The NL-4 is a traditional plated design. However, unlike standard designs, the NL-4 has raised diamond coated structures.

It is the edges of these raised diamond structures that are doing the heavy work.

The NL-4 sports an arrow-rake pattern for heavy material removal. The long straight edges cut very well across stones. The spaces in between the ridges allow for slurry to move through and keeps the surface from gunking up. 

Do not use this lapping plate for sintered ceramics or diamond resin stones except Nano Hone diamond resin stones. Our compound is really different from other manufactures. Ours is much softer than others.

Very substantial!

Given its low rung on the Nanohone flattening totem pole, I was concerned this would be a small ineffectual stone. Boy was I wrong. It’s long and strong, and gets the job done!

Fantastic product.
Does exactly what I want it to do and keeps my stones flat.

Cody Thweatt

use it everyday about 5 times a day. Holds up well and flattens ceramic stones quickly

It's a Beast!

This cuts and flattens stones with ease. I use it on Hap's stones 400 Grit + and my naniwa stones. It feels substantial in the hand due to it's size and weight. I like being able to place it on the stage or flatten from the top down by hand.

I'm sure this will last a very long time.

Hi Cole,
Thank you so much for shearing your experience with our BEAST! Since diamonds are dispersed evenly throughout the metal button matrix, this plate is tough and yes, will last a longest time. Enjoy!

Early Buyer - Still love it!

I have, I think, serial number 3, this thing is worth it's weight in gold, its a product made to get a job done. I use it every time I sharpen, and it still is in great shape after the years. This is a buy once, cry once kind of tool. Don't waste your time with other methods... if you know you will be in this craft a while, invest in this and forget about worrying on stone flattening.
