Drag Knife / Utility Blade Safety Cover

thingiverse

This is a protective sleeve for utility blades on retractable knives. The retaining nuts that secure the retractable blade in place can be notoriously difficult to loosen, and when they finally yield, it's not uncommon for users to struggle with maintaining control over their hands. To mitigate this risk, simply 3D print this cover, which features a recessed area measuring 6mm in diameter to accommodate a magnet, thereby shielding the exposed tip of your retractable knife.
