I may be wrong [it has happened before] but I suspect some feature of the design was covered by one or more 1913 patents … Metmo claims to have “perfected” the “invented” … so we could be looking for a bench-clamp or whatever for its parentage.
Invented in 1913, perfected in 2026. An icon of industry re-engineered for the modern day.
it seems 1913 was a very busy period for wrenches, vices, clamps, etc.
… it’s interesting to just browse espacenet for design ideas.

P.S. … I note that the two items illustrated differ in their construction
I wonder if they will both be marketed
