Two interesting - if more or less useless - devices.

[conuly]

A personal handheld toaster, which would be more useful if it didn't take so long to toast bread

And a tool to make ribbons of butter, which would be more useful if one ever needed ribbons of butter.

You need ribbons of butter so you can make decorative butter sculptures at Passover like my grandma. I can't find a picture anywhere on line that wasn't done out of a mold, but she made butter roses that looked completely real, with parsley for the leaves, all by hand with just a butter knife and patience.
