Hey friends. Need some help.

I bought one of these a few years back and carried it every day as a tape cutter / fidget thing. Recently lost it and cant remember the brand. You use your thumb to push up on the face of it and pointer finger to rotate out a tiny replaceable utility blade. Its a great little tool. If anyone knows what its called or who makes it, itd be of much help. Thanks.

PS the shitty drawing is pretty close to scale.
