Bill, I can help some on this subject.
I worked with Liquid Metal for awhile back in the 90s. Built several knives from it and wasn't impressed. The least bit of heat while grinding would make weak spots. It was difficult to put a decent finish on and you could never get that "sharp" edge when sharpening.
I still have a few pieces on hand, as a historical thing.
The maker that brought it forward isn't using it anymore. It can cause some medical problems that are hazardous.

Also, do a Wiki search and read about Gallium and skin absorption.
If it's the future, I'm going back to school to learn plumbing or carpentry..
