I still have my grandmother’s one like the one on the left. Works like a dream. Unfortunately, I can’t use it with any regularity because my wrist hurts too much sometimes. I sprained it ages ago & it didn’t heal correctly, combine that with arthritis and that equals looking for a more expensive electric opener every few years or making my husband open stuff for me (which he doesn’t mind, but isn’t always here when I need or want something open).
