Suggestion: Make the finished hand-tool a different color.

Since you are reusing the model for the basic hand-tool, it's hard to tell at quick glance which tool you have selected while scrolling through your equipped tools.

I can't. I mean, I could, but I won't, because changing the collor would requires using a whole new material and redoing all the UV-Mapping, wich I an not goind to do 🙄
