The Independent Living Centres (ILC) do have new/different names in different states, and are excellent resources.
They don’t sell products. They display products, and have information on retailers of products. They have occupational therapists (OTs) who can advise people with limited hand dexterity or use, people with limited vision, people with limited hearing, people with limited mobility etc. If your friend makes an appointment, or even just goes to see what the nearest ILC has on display, he or she may find multiple things that make life easier as well as a solution for peeling vegetables and a solution for chopping vegetables - it is great to pick up and feel all the different aids to compare what may be a better solution for a particular person.

I noticed a favourite aid on one of the above pages - Alligator Food Chopper. It is a helpful aid even for fully able folks - chops a halved onion with one push and no tears, works for all sorts of vegetables; my Mum liked her Alligator because she had limited vision.
