Best tools are simple in design and their use "instinctive" and not requiring a video to figure out how to put them to work..
This toy is a good idea and I believe is well built, but I don't see how it can compete against a good knife + a decent multitool in terms of "sitting comfortable" in the hand.
A skilled person with good hands is able to do wonders with a simple quality knife. Someone with a "pair of left hands" might find it useful at first for some tasks but lack of basic skills and imagination will stop him at some point and this nice gadget will be put aside, together with the titanium multitool and the ceramic coated survival knife.
Sorry for my harshnes and scepticism, but believe me that I have been using hand tools, power tools, machine tools etc, for a good while, both in the shop and in the field and never felt the need for anything special beyond TRUE PRO tools.,
Have fun
