I suggested those 2 monsters for a good reason. after beating Tipping the Scales, you'll be able to trade Najarala parts(Shells and Chilling beaks) for Ceanataur parts. If you make a mix of certain Ceanataur and Gore parts, you'll be able to get 10 points to Handicraft* and therefore Sharpness+1. you can also use the 3 slots in the set to get speed sharpen.
