Okay, since this issue has been out for a long, long time, I feel I can post a better, unedited reference that doesn’t involve blurry artichokes. Still gonna tag this as spoilers. Behold, Whirl’s fine manipulators, or, as I like to think of them, his secret deedly-boppers.
The first picture seems to suggest that each one has three fingers, and they are also plainly capable of swiveling, folding, or extending as needed to accomplish tasks requiring manual dexterity. I mean, Whirl successfully eased open a spark case and successfully implanted a spark using them. He might not be the craftsman he was, but I bet he still has a deft touch.
The bottom picture is the ref I really wanted, to show the way his claw splits and slides back.
