Mora Knife with ERGO grip and sheath

grabcad

The Mora Knife blank, purchased for $9 on Amazon, features a custom grip and sheath designed by me using calipers and CAD software in SpaceClaim. The blade model was extended slightly to enable smooth insertion into the grip, which was created from a hand-formed clay impression scanned with Geomagic Capture. Geomagic Wrap was used to generate an automatic NURBS surface from the mesh data, which was then employed to cut the sheath in SpaceClaim. The sheath's thin areas provide just enough flex for easy insertion and secure retention of the grip. This innovative design also incorporates geometric fill patterns and lightweight materials that make the sheath rigid and buoyant if dropped in water, while allowing for pausing during printing to insert objects.
