Finally an anvil and a forge!
And the best thing about it (beyond its usage) is that the CD is equal to its lasting time (the CD is not longer than the lasting time so you haven't have to wait a CD - at the worst situation you would have to return to the last location you put one within the last 5 minutes while you were travelling and gathering/melting/crafting; if you are still on the same zone, or near to it of coarse).
No more need to HS'ing/teleporting or flying to the nearest settlement to find an anvil and/or a forge, you can just craft (or just melt) when you finally gather the materials. Or just to open bag spaces.
And other workers such as blacksmith and miners would appreciate it too ;)
