Looks like this product is called AmazingHand (and there are billions of "hand"s in the world), so the title might have some room for improvement as far as searchability goes.

Would it be possible to have tendons running through the arms, so the weight of the hand is reduced?

Most tendons materials are elastic. That lead to create calibration problems and require proprioceptive sensors in the hand

Pollen Robotics and HuggingFace are doing a lot for robotics right now!

This looks like a nice, approachable robotic model of a human hand that can be printed and experimented with.

But... is a human hand the best design for a robot to grip things with? Or could we surmise that the human hand evolved as a pretty good hand given the materials and senses that were available to evolve humans from, while in theory a totally different design might be optimal for gripping when constructed from metal, plastic, motors, etc.?

It’s easier for humans to train a human hand

Huh, never thought of that

I wonder if companies are experimenting with materials like UHMWPE for non-elastic, high strength-to-diameter tendons.

I dont know if you'd have to weld the dyneema to the anchor points, though

Will Cogley has had a few different designs with tendoned hands.

So, there are designs out there for that too!
