I recently got an old very light weight Hosmer hook with dedicated angles and grooves made specifically for hand writing, painting and other calligraphic entertainment requiring to hold a pencil like item at the right angle. 

What an item! Personally I find this tops just about any other terminal device that I have for office work.

I am about to put up some pictures about the system that they put on my arm but I am not too happy with it. I'll post these images later and put the link up.



The problem is that mostly it inadvertently disconnects if the cable happens to be not under too much… Continue

I would be interested in collecting norms and sizes used for cable control ball connectors. I use Otto Bock Movohook ball connectors (ball diameter 5mm) but after hooking (broom ting) up a Dorrance hook I realize the US norm is different.

Thank you.
