Knife Sheath

thingiverse

To prevent your knife from getting dulled by accidental impacts, you'll want to keep it encased in a protective thin-walled sheath made especially for sharp knives. This cleverly designed holder is also there to shield your fingers from cuts and injuries. When creating one, pay close attention to the dimensions – an opening width of around 10mm has been found effective by many users and eliminates the need for extra support structures.
