Simple Keychain Knife - Utility Blade - EDC

thingiverse

I designed this keychain utility blade knife after printing the Talon Utility Knife (which I credited as a remix source, although it's not a real remix more an inspiration) and the "Keychain Knife with a Button" (https://www.thingiverse.com/thing:4747489). Both are really great little knives, but I discovered that for me they were still a little big for carrying on a keychain. So I went to make the simplest and smallest version of a keychain knife that takes a utility blade. My version is just one part. It's best printed upright with tree supports (see picture) and needs very little post-processing that way. If you're wondering how it works: The "back" of the knife is bent inwards, so it applies pressure on the blade. In the top left corner is a small "knob" inside the case. The blade is pressed against it (or against the case behind the knob to be precise), so it can't open by itself. If you want to extend the blade press on it and slide it out. The "knob" will fit in the little groves on top of the blade so the blade can be secured in two extended positions. I modelled this to use "Bosch" Utility blades, but they are approx. the dimensions of stanley blades. I do not take any responsibility for any injuries you might sustain from using this model (blades are sharp!).
