Crafting with Damaged Item not working.

So I am trying to craft with a hammer and it will work the first time around but as soon as I try again it won't work. I tried looking around for this issue because I'm fairly sure this question has been asked multiple times, but haven't found anything.

This is my Hammer's class

public class ItemHammer extends Item{

public ItemHammer(){
	this.setMaxDamage(100);
	this.setNoRepair();
	this.setMaxStackSize(1);

}

@Override
public ItemStack getContainerItem(ItemStack stack){
	ItemStack result = stack.copy();
	result.setItemDamage(stack.getItemDamage() + 1);
	return result;
}

@Override
public boolean hasContainerItem(ItemStack itemstack){
	return itemstack.getItemDamage() < itemstack.getMaxDamage();
}

@Override
public void addInformation(ItemStack stack, EntityPlayer player, List tooltip, boolean extendedTooltip){
	tooltip.add("Uses Left: " + (stack.getMaxDamage() - stack.getItemDamage()));
}
}

I am registering the recipe normally because I thought if you didn't defined a metadata value in recipes it ignores the value(like how you can use all 3 anvils in a recipe with just, Blocks.anvil) and it wasn't until you did something like,

new ItemStack(Blocks.anvil, 1 ,0)

that it cared what metadata was used in the recipe.

This is how I have the recipe now.

GameRegistry.addRecipe(new ItemStack(Rustic.formedCopper), "HC", 'H', Rustic.hammer, 'C', Rustic.copperIngot);
