Looks like quite a nice billhook mate.
I've always found them to be pretty decent and versatile. But that depends on the blade shape.
The hooked tip does get in the way though, especially when whittling a project on a work stump. The tip gets stuck and only the first section of the blade is of any use. I used to use them as draw knives too, the straighter the main edge is the easier it is, but even with shape and curves it's no big deal.
Imo their best attribute is their compact size and heft. They aren't as good a chhopper as an axe or as good a slasher as a machete but they work well and pack a punch!
Good shout on the scabbard, much safer than a soft sheath. If that one breaks or you want to try another, have a pop at making one from plastic gutter pipe. All you need is some pipe, a hacksaw and an oven!
(If you need any help, tips or advice on sharpening or refurbishing the billhook feel free to pm me. I've restored boxes of them over the years.)
