I have never been truly satisfied with the fillet knives I have owned. Most wouldn't keep an edge to my satisfaction or were uncomfortable if I had many fish to fillet. I am sure that some of the discomfort comes from arthritis, I was warned by a Dr. When I was twenty that it would become an issue for me when he looked at an ex ray image of my hand. So I recently decided to take matters into my own hands.
I had an idea of what would work for my uses, so I decided to sketch what I felt would work.

I chose 15N20 steel for this project for its properties and that I have the ability to heat treat it myself. I started with .080" thick stock and ground out the profile.

I then performed the heat treat techniques for this steel. Thermocycle, quench in heat treat oil and temper shooting for 60-61 Rockwell. I then ground the primary bevels and distal taper. I put an edge on it and began testing to see if I achieved my goals in heat treating.

I sliced up a pizza box without any noticeable difference in how it cut.
Some old pine knot to test how tough the blade is.


No damage to the edge and still cutting some hair, not quite as much as at first. But I am still liking where this is going. So it's time to see if it's got the flex I was hoping for.

Good so far. Moving on to the finish. I really like a hand rubbed finish.

More tomorrow.
