Uncrafting

[Yokmen]

Receiving 60% or 80% of the initial recipe could be a nice idea.
But we shouldn't be able to uncraft mats like Skull Fragments or Black Steel.

For example :

20 x Hardened Metal
20 x Twisted String
10 x Dye
5 x Wood of Glasir
5 x Wooden Slat

Item Created:
1 x Platform


=> Uncraft Platform and receive :

12 x Hardened Metal
12 x Twisted String
6 x Dye
3 x Wood of Glasir
3 x Wooden Slat

The only problem i can see is how can we uncraft gears including Phoenix Feathers ?
