The truss system of the spine looks curious, but it works gangbusters.

The crazy design of this titanium 5″ woodworker’s fretsaw from Knew Concepts is, I think it’s fair to say, the first thing you notice. But use it and you’ll quickly come to appreciate that the structure helps to make it lightweight and rigid, and the clever tensioning mechanism snugs up the blade tight – and keeps it there.
This frame is a redesign of the company’s earlier titanium woodworker’s fretsaw, the frame of which was a continuous piece of 1⁄8″-thick titanium (the same design as the aluminum woodworker’s fretsaw currently available). But in an effort that was initially meant to reduce materials waste and take advantage of more readily available 1⁄16″-thick titanium, designer Lee Marshall came up with a riveted truss system for the saw’s spine that’s even more rigid than the original (he calls it a “birdcage saw,” in honor of the Birdcage Maserati). The spine is riveted to 1⁄8″-thick titanium arms.
