I saw a thread before, or a wikipage i think regarding the Legendary Red Tools that we will get in the future .. As of now, we already getting the 4 of it, and who-knows-when will we get the others, but as far as i saw in that thread or wiki, the Shichiseiken is still the Tool in that type or Tool Slot .. The necklace and Scroll i think have new kinds too ..

Better check iPackaPunch's wikipages, i think that's where i saw that thing ..
