These two: and I didn't buy either of them. My grandmothers did.
The pastry blender was bought by Grannie when she took her new DIL (my mother) to a Good Housekeeping Exibition in Bradford in 1947. It has done yoeman service ever since and is as good as new.
The other implement, which I have never seen in Britain, is called a hakkekniv in Danish and was part of the kitchen utensils that my Danish grandmother bought for my mother while she and Daddy were engaged, so it is very slightly older than the pastry blender.
You can chop anything you like with it from almonds to cooked or raw meat. It takes a little longer than using a mincer, but it is far easier to wash up afterwards. As far as I remember it didn't evem need sharpening until the mid 1980s.
Seen these many times in the U.K., even had one once, gave it away as couldn’t get on with it, it’s called a hacoir, can be used to chop many things as you say.
