One of things I found difficult early on in my recovery was cutting vegetables or meat. It was difficult to not only control the knife but holding it and at the time having enough force o chop through tough veg.
I came across a program on Alaska recently and the locals were using a Ulu which is a curved bladed knife which looked so easy to use. Strangely called the a "woman's" knife by the native tribes but it is used by men and women.
I actually found a UK supplier who had them at a reasonable price £9.95 rather than the £40+ some places wanted. Ordered one and it works really, really well. My wife whom has a frozen shoulder could use it as she also struggled with a normally knife.
You can use it many ways but the easiest is to just rock the blade back and forward over what you need to cut. It is so much easier and safer.
