Firebird,
Like 36sedan mentioned on another thread, it's amazing what you find when you Google with some creativity. There are a lot of "Assistive Technology Products" out there to help people with tasks, whether it's loss of grip strength or reduced use of a limb or limbs. Here's one that a person can search based on function, or based on tasks, and there's even a section "Can You Make Me A __________?" for someone to request help for a specific need that's not readily available on the market - Assistive Technology Products, Assistive Disability Equipment - Disability Work Tools Products
