Issue Description:

When you empower the darksteel shears items that require shears get doubled.

What happens:

Whenever an empowered shear is used on an item that requires it, i.e. leaf blocks instead of getting 1 item, you get 2.

What you expected to happen:

When you break a block with the shears or shear a sheep you only get 1 of the block or a normal amount of wool.

Steps to reproduce:

1. Empower Darksteel shears
2. Break 1 leaf block from tree
3. Get 2 blocks instead of 1
