Talic seems to have a usable line of reasoning for a UMD tool. Of course, by the logic of "It's up ot the GM to disallow it", you can say "I wish the game was over" and succeed, with Wish. RAW isn't as useful as common sense.

There are no listings for these specific items in the RAW. But there IS a listing for MW tool, and that is what's being used. The descriptive text? It's there to satisfy plausibility, not legality.
If in your games, commoners may begin orgies of grappling to move at supersonic speeds, that's your business, but the rest of us will save pure RAW for a world of silliness.
