OK, love the mod, but I do have one minor gripe. Why is Titanium better than Steel?
According to Quora (https://www.quora.com/Is-titanium-stronger-than-steel-and-what-is-it-about-titanium-that-makes-it-so-difficult-to-manufacture):
"Titanium has higher tensile strength per mass but not by volume. A kilogram of Titanium can take more force than a kilogram of pretty much every other metal. However titanium is not very dense (which gives it its light weight). What this means is that while a kilogram block of titanium is stronger than a kilogram block of steel the block of titanium is almost twice as large as the block of steel. So unless someone wants to make their product almost twice as large in order to get that strength advantage steel is always preferable for making strong objects. Steel is also harder than titanium. Titanium deforms more easily than steel. This is why titanium blades are always on par at best with equivalent sized low grade steel blades as titanium blades lose their edge very easily. For things like nuts and bolts and screws equivalent sized steel items are always preferable unless you want to sacrifice strength for lighter weight (which you shouldn't for things like bolts and what not)."
So a Titanium version of a 10lb sledge would have a 5lb head, and titanium axes, picks and blades would wear out faster...
A better material (IMO) would be Tungsten, which is more dense and harder than steel.
...Sorry, just my 2 cents... Love the mod though!
