Coin Pocket Utility Knife

A printable knife made with the following design goals:

• use standard and interchangeable utility knife blades
• as small as possible
• operate with one hand
• “lock” open and close
• reasonably strong
• simple and easy to print

I use the following…

• petg @ 0.12mm
• no support / brims
• note the orientation in the photos screenshot
• the sliding action will feel a bit rough at first, but smooths out with use (a little dab of silicone grease helps a lot) 

Updates

1. Mar 2024 (v2): cleaned up the models, improved tolerances, added keyring hole, better retention of blade holder when applying a lot of downward cutting force
