The Madrone comes ready to work, but no working edge lasts forever. Use it the way it was meant to be used, and eventually it will need to be resharpened.
The key is understanding what the knife needs before you start. The Madrone uses M390 steel, a premium stainless "super steel" known for excellent edge retention. That means it holds an edge well, but it also means you will want an abrasive that can remove material efficiently once it is time to resharpen.
Diamond abrasives are a smart choice here because they remove material fast enough to work effectively on a high-wear steel.
Match the Factory Angle

The Madrone is sharpened at 20 degrees per side. That number matters.
Match that angle and the job gets much easier. Miss it, and it is possible to spend a lot of time sharpening without really improving the edge.
A guided system makes angle setting simple, but even without one, there is an easy way to check your work: color the bevel with a marker, make a few light passes, and see where the ink comes off. If the marker is being removed evenly across the bevel, the angle is right.
No Burr, No Sharp

This is the step that matters most.
No matter what sharpener is being used or what shape the edge is in when the work starts, the edge is not truly sharpened until a burr forms. As material is removed, a burr will begin to develop along the apex. That burr needs to run from heel to tip. Until it does, the edge has not fully come together.
No burr, no sharp.
Refine the Edge

Once the burr is there, the rest of the process is about refinement. Move through finer abrasives and clean up the edge until it is as sharp as, or sharper than, when it started.
The coarse abrasive does the heavy lifting. The finer abrasives improve and polish the result.
Maintain It Before It Gets Dull
The easiest sharpening job is the one that never turns into a major repair.
Honing and stropping help keep the Madrone performing well without needing a full resharpening every time the edge starts to fade. Regular maintenance goes a long way toward extending edge life and keeping the knife cutting the way it should.
The goal is not just to sharpen the Madrone once. It is to know how to bring the edge back whenever the time comes.
