@B214 "All Sacred Gears are common, it just depends on the ability and rarity..."

I know what you were trying to say, but your comment doesn't quite make sense. If all SGs are common, then they can't be rare.

@Dragoniahadesking If you didn't get what he was saying, he meant that with the exception of the 13 Longinus, the Sacred Gears are not unique. Some SGs are rarer than others, but there can always be more than one of them -- though in most cases we don't know how common they really are as Ishibumi-sensei hasn't told us. As for whether or not it is possible to replicate a SG... if Euclid can successfully replicate a Longinus such as the Boosted Gear, than yes, it is possible to replicate just about any SG. However, as B214 pointed out, there is little need to replicate them since, with a few exceptions, multiple copies already exist and more than one SG has abillities that overlap, and if all else fails an artificial SG can be made... and more than likely custom-made to better fit the wielder.
