Maw Claws of Thrax come with a model that has rending claws or MRC (it doesn't replace them, it comes in addition to which is fine because they don't have an actual profile). But their description...
the dread beast that spearheaded the assault had a pair of symbiotic fang-lined pincers.
...sounds less like Rending Claws and more like the Grasping Talons on a Lictor.
I am thinking about modeling a Hive Tyrant with them mostly for funsies. I am thinking of using a fleshborer Hive as a base and trimming them up to be a lot thinner and adding lots of spikes to the inside. Anyone else get the same impression as me? Anyone else make their own Maw Claws?
