Razor blade neck knife

thingiverse

This is a compact neck knife that takes standard razor blades and attaches to a convenient neck sheath for instant access. Print Settings Rafts: Doesn't Matter Supports: No Infill: 50-100% Notes: Print at higher infill settings to reinforce the spine. Post-Printing Finishing Loop some paracord or other cordage through the holes at the top of the sheath so it can be worn around the neck, and insert a razor blade into the groove on the spine. Don't worry if it doesn't go all the way in – just ensure that it's flush with the front of the knife. You may want to sand down some of the edges on the handle for improved ergonomics.
