Hook Knife

thingiverse

UPDATE: V3 allows you to print the knife with a cutting edge facing sideways, giving it significantly more structural strength by keeping the Z-axis much shorter. An added blade cover also makes accessing the blade much easier, without requiring any support material. As an avid paraglider, I know that having a hook knife is a must-have in situations where flying over water occurs. It's also an essential tool for individuals involved in water sports that involve lines, such as kite boarding or white water kayaking. The hook knife uses a standard double-edge razor blade, although other blades can fit into the blade slot. Print the cutter opening facing upwards using brim for extra adhesion, and prints well with 25% infill and 0.3mm layer thickness. This is still a work in progress, so I welcome comments from others.
