I wanted to make a sheath or mask for the hatchet I recently rehandled for the make a handle bb but the belt loop requirement lead me to grab a different hatchet for this bb. I also would echo the detraction from that requirement as I don't like the uneven weight of anything but the smallest hatchet and can't really imagine anyone particularly wanting to carry any axe that way for much time at all. Also the only real universally applicable sheath pattern is the one shaped like an envelope with a hole in the bottom which the entire length of the handle must pass through. I find that pattern clunky and unappealing. I wonder if the edge protection and belt attachments were two separate pieces if that would still meet the bb requirements, I've seen that style and think it would be a less cumbersome way to go.
Anyway, I chose to make a mask for the lightest hatchet I had that needed one that also had enough material on the poll to allow for the two-strap style I devised. I used bark tanned cow hide that I tanned myself, this piece came from the belly area so wasn't overly thick. I did the usual process of tracing the hatchet and making a paper pattern and then transferring that to the leather. Once cut out I spent some time dressing the leather with neatsfoot oil and softening it to a more pliable condition. A welt was also cut out to be stitched in between the folded layers where the edge goes in the sheath, this is what protects the stitches from being cut. I had to re-punch some holes and the welt got a bit chewed up but in the end it still looks fine if you don't look too closely. I'm pretty amateur and haven't done leatherwork for a year or two though maybe I was just sloppy. I also made a groove for the stitches on the front and back edge before punching which was a mistake, the back edge should be grooved after punching so it's aligned and neat. Four holes were punched in the back and cut between them to make the slots for a belt to pass through. I waxed linen thread with beeswax and stitched with two needles, going through each hole with both needles and pulling tight, I forget what that stitch is called but it's commonplace for this task. I punched holes and set down the snaps similarly to how one would a rivet. A little clean up trimming and edge burnishing and it was all done.
