Reddit mentions of Singing Rock Edge Axe With Adze RK008SS00A

Cool idea. Does she have a quiver and arrows? If you can swing the expense, I think a climbing axe would really bring it all together. I checked Amazon, and sorting low to high, this is the cheapest one they have that looks close to the style used in the games.

It's the wrong color, but you could paint it. Some cheap rope and and a walkie talkie to go on a belt would be a nice touch as well.
