Or maybe they should just get rid of it? Get rid of the stupid thing on the waist too. They've already gotten rid of plenty of visuals that were more aesthetically pleasing than that lame rotating clamp and steampunk fanny pack.

When I first started red mage, and realized that both the sword AND the gem are unique for each weapon, I immediate though of how badly machinist was screwed up by the devs. None of the machinist accessories are designed to match the weapon, there is little variation in appearance, and they clash hideously with just about every armor and weapon design in the game. Meanwhile every samurai sword has a matching sheath, and every bow has matching quiver and arrows.

Either redesign the machinist equipment to be unique for each weapon, or just get rid of them.
