(Note; Yes, I know there's a Sharps General but IMO this specific subject rates a separate thread.)

Something that's never talked about on /out/ is sheaths for various bladed tools like knives and axes.

What's the best material, leather or synthetic (or even wood, for larger axes)?

What are things one should look for in a sheath or ask for in a custom-made sheath?

Where does one get custom made sheaths?

Fancy embossed decorations, or clean and plain?

Brown / black only, or are colored sheaths acceptable?

(Also; post pics of cool sheaths, this being an image board after all)
