Oh don't worry we're not making it look nice. We want it to look like a scrap yard came to life. The scoop (not on yet) is some rusted metal, so it's going to look really rustic come the end.

We don't really know what the teeth are, but they are some sort of steel with what I assume a tool steel on the tips (which are seriously sharp). Dan picked them up at a car boot for 50p!
