My Grandmothers Pizzelle maker. Gran died in early 70's and she had it a good 30 years or so. Then Mom got it, and now it's mine. It's not used nearly as often as a toaster, or most other appliances - but it works like a charm when I do have occasion to dust it off.
Some of my other cherished items from Mom and Gran that I use regularly ... mom's "salad" bowl, her chefs knife, and grandma's wooden rolling pin which is still covered in the leg of grandpa's long john. I've warned my husband that if he DARES to wash that long john he faces stiff consequences - it's well seasoned with decades of butter and flour and still has a hint of anise scent!!
