I'm doing research for my culminating undergrad project on what kind of knives are appropriate for elderly persons, aged about 65-75 years old, and I've got three main questions:
A gerontologist told me that the elderly usually prefer smaller knives, but why would that be? I would have thought bigger ones have more balance and more weight to cut through things.
I'm focusing on arthritis as well, because about 50% of people aged 65 and older have some form of it. I've seen those kinds of knives that look like an upside-down scythe where the blade is below the handle. What other kinds of handles are ergonomic like this?
Most importantly! I need advice on what kind of blade is high quality but long lasting (and keeps sharp for a long time). I've read that ceramic knives can break easily, so stainless steel is probably the way to go. Is carbon steel better, or a different material? And what about bevels? Do certain kinds stay sharper for longer than others?
