You may have heard of the SawStop; it’s a safety device for table saws that can instantly stop the blade if it comes in contact with a finger, preventing injury. Until now the videos I’ve seen have involved hot dogs being saved from grievous injury. But in this Discovery channel clip, SawStop’s inventor puts his actual finger where his mouth is.

Madness. He’s gotta have quite a bit of confidence in his engineering, but also whoever does his manufacturing and QA. Remind me never to invent anything that guarantees you can fall into a wood chipper and come out the other side unscathed. I doubt they’d be able to air that on the Discovery Channel.

Marvel at the H.O. Studley Tool Chest. Studly, indeed:

Considering how many tools it holds, the famous chest is really quite small; when closed, it is just 9 in. deep, 39 in. high, and just more than 18 in. wide. Yet it houses so many tools — some 300 — so densely packed that three strong men strain to lift it.

For every tool, Studley fashioned a holder to keep it in place and to showcase it. Miniature wrenches, handmade saws, and some still unidentified piano-making tools each have intricate inlaid holders. Tiny clasps rotate out of the way so a tool can be removed. In places the clearances are so tight that the tools nearly touch. The chest, which hangs on ledgers secured to a wall, folds closed like a book. And as the chest is closed, tools protruding from the left side nestle into spaces between tools on the right side. Amazingly, despite being so densely packed, the tools are all easily accessible.

There’s a poster.
