What is best choice for a manual can opener?
That is a personal preference. You just have to try some and see what you like. It should be reasonably easy to use and comfortable. If you only use one every now and then, go for about any can opener. If you have weak hands use an electric. There is a type of can open that cuts the side instead of the top. It leaves a nice edge which is not sharp. It is considered safer than the type which cuts the top of the can. It takes some getting used to. Also, if you accidentally let it slip, it won’t work at all on that can. With the type which cuts the top, it can slip and sometimes still work with use of more force on the handle.
