Cast iron skillet and cast iron griddle. Both are well over 100 years old at this point.
That is used at least weekly.
My garage fridge is from 1950. Out first house we purchased in 1998 and the old couple left us this garage fridge. It’s been the garage fridge ever since. It made the move with us and weighs a ton even though it’s a foot shorter than a regular fridge. For fun if you hold onto the handle too long it’ll give you a little jolt. It’s red for whatever reason. Might give it a new coat soon.
Dining room furniture came from my grandmas and it’s very early 70’s. Our kitchen had 1966 appliance but we JUST remodeled.
Have other stuff that is older but never gets used.
