Line Cutter

As i'm diving into the unknown, i don't want to get caught on fishing lines or other stuff.
I made these easy to bring line cutters. It cuts up to about 1cm thick lines.
Of course also for daily use.

It fits standard Stanley knife blades you can buy in your local hardware store.
And is secured with your trusty M3 size nuts and bolts.

It's a work in progress, i had already allot of designs and tests. please give me feedback so i can further improve my design.
