Kinefinity Electric Screwdriver

Building and stripping a cage rig is dozens of small screws, and a hex key does it slowly while a power driver does it too fast and strips the head. Kinefinity and Wowstick built this one to sit between: 200 RPM and a controlled torque range, so it drives quickly without over-tightening into aluminium threads.

It switches between powered and manual automatically, so the same tool spins a screw down and then torques the last turn by hand where feel matters. Light enough to live in the accessory pouch rather than the tool case, which is the difference between having it on location and not.
