Making an OTF Folding Knife from Scratch

We’ve seen quite a few knives being made over the years, but they usually have fixed blades. Metalsmith Koss shows off by machining a more complicated knife with an out-the-front deployment mechanism for its M390 steel blade. Its titanium handle design reminds us of those folding plier multitools, but you can’t exactly use one of those for self-defense.

A Camera Grip That Can Charge your iPhone

Belkin’s PowerGrip is for those who shoot lots of video with their iPhone. It solves two problems at once: It provides all the juice you need for a long shoot, and it provides a comfortable camera-like grip.

It attaches magnetically, and can be used in either portrait or landscape orientations. There’s also a physical shutter button, which works via Bluetooth.

The 15W battery has enough capacity to charge your phone "up to 1.6x," the company says. It also features a retractable USB-C cable and a second USB-C port, if you want to use it to charge other devices. And the bottom is tapped with a 1/4" thread so you can attach it to any tripod.

It can also be used as a phone stand.

Runs $80.
