The Pure Leverage Hard Drive Crusher is a mechanical device designed to cheaply destroy hard drives .
The Pure Leverage hard Drive Crusher destroys the enclosure, but most importantly bends the disks.

It would be impossible to flatten them so perfectly that they could ever be spun and read again. Some drives have glass disks which shatter.
Pure Leverage claims on its website that the device “has been reviewed by the NSA and meets the requirements for ‘hard drive destruction.'”
