[1.8] Custom tool not rendering

Not sure why, but my custom tool isn't rendering at all.  Not sure what's wrong.

Render statement:

ItemModelMesher renderItem = Minecraft.getMinecraft().getRenderItem().getItemModelMesher();
public static ItemToolHammerDiamond itemToolHammerDiamond = new ItemToolHammerDiamond();
renderItem.register(itemToolHammerDiamond, 0, new ModelResourceLocation(CCModpack.MODID + ":" + ItemToolHammerDiamond.name, "inventory"));

Hammer Base:

Diamond Hammer:

package com.cclloyd.ccmodpack.itemtool;

import com.cclloyd.ccmodpack.CCModpack;

public class ItemToolHammerDiamond extends ItemToolHammer {

public static final String name = "itemToolHammerDiamond";

public static float attackDamage = 5.0F;
public static ToolMaterial material = ToolMaterial.EMERALD;

public ItemToolHammerDiamond() {
	super(attackDamage, material);
	setUnlocalizedName(CCModpack.MODID + "_" + name);
}

}
