No, there is no mention of the shank being hinged in their website blurb. The entire anchor is bolted together, however. Shank bolted to the fluke, roll bar bolted to the fluke, etc. So it can be taken apart and stowed.
The only feature I find potentially beneficial is the two extensions that the rollbar bolts to. This in theory would increase the sideways "knife down into the bottom" leverage applied to the fluke. This is the purpose of the two "skid plates" that Peter Smith added to the basic Bugel design when he created his anchor. I don't know if the two extensions on the Mantus anchor help, hurt, or make no difference to the overall performance of the anchor.
But given the excellent performance of all the rollbar anchors I don't see at first glance any reason why the Mantus would be in different in this respect. Don't know the effect bolt-together assembly has on an anchor like this.
