For some, the appeal of having a leather sheath for a much-carried or valued tool is high. However, these are typically single-purpose items, sized and dedicated to a single object.

Silver Fox Tool, a small UK-based hand tool manufacturer, has a different idea. Their Mule Pouch is designed to carry several items, and is user-configurable. Only the side pocket has a dictated size.

The manufacturer refers to the brass fasteners as "rivets"--which might be a British thing, as in the 'States rivets aren't reversible--but they're actually tiny hex-head bolts and (I believe) T-nuts. Six of each are included and the Allen wrench is thrown in too, so you can move them around as you please.

A larger offering is their Mule Book, which comes with a dozen fasteners:

Lastly, their Mule Note variant leaves one side free for a small notebook.

The hand-stitched leather objects run $70, $92 and $98, respectively, extra if you opt for engraving.
