Here are some public domain images of adventuring gear or adventuring equipment that you might find useful for handouts:
Grapnels or grappling hooks:
a 10' pole:
Crowbar or prybar:
Also, these are not my target quality, I would prefer higher resolution images with a consistent style, but this is what I've managed to find in the public domain in the last five years or so. I hope you can use them to make some cool stuff.
