Generic simple blade sheaths

This sheath was mainly for a broken garden shear that got taken apart and converted into a blade.

The sheath consists of 2mm sidewalls with variations in the thickness of the opening, depending on the blade size.
The nub just covers an exposed bolt for safety, or just to reduce the sharpness so that it doesn't damage pockets.

More variants will be likely be added to in the future as I fit more blades.

(Update, 2025-04-21) I particularly like how this design is universal, the 3mm variant fits side cutters as well.
