Description of the issue:

IE tools cannot be repaired with what items it would make sense to repair them with.

The tools missing what I think are natural repair materials are below:

• Engineer's Hammer
• Engineer's Wirecutters
• Faraday Suit
• Steel Sawblade
• Possibly (?) Rockcutting Sawblade
• Mineral Survey Tools (I'll explain below)

What I think the tools should use:

• Iron: Engineer's Hammer, Engineer's Wirecutters
• Aluminium: Faraday Suit
• Steel: Steel Sawblade
• Diamond: Rockcutting Sawblade
• Written Book or Paper : Mineral Survey Tool

The mineral survey tools use a book/paper because I imagine the tools being used up as the data book being filled, so it makes sense to grab a new book or more paper right before you finish out the last one - the paper exists if repair must be four items

I dislike the sawblades being repairable, I think I prefer people to craft new ones.
However, making them recycleable sounds like a good alternative!

Drill heads are repairable. but that does make some sense!
