Thanks! Yes, that piece is laser cut. It's actually the waste portion of the pickup cavity route from my main template, so I'm making use of something otherwise useless.
Hahaha as for the Katana, I have this terrible habit of not actually explaining what in the hell I'm talking about half the time (ask my wife, I drive her crazy). It's an adjustable fret leveling tool made in Japan. Essentially, it's a machined aluminum beam with a truss rod inside. You adjust the beam to match your fretboard's contour under actual string tension, then use it to level the frets.
Here's the website if you're interested in taking a look. I don't know that it's any better than a traditional fret leveling job, but I aim to find out! Actually, since it was so expensive, I think I'll write up a review and assess its value after I use it.
