Butter-keeper spreaders hold a stick or half stick of butter inside a tube. You remove or open the cap to expose the butter, glide the exposed butter over warm corn, and press a plunger to advance more butter as needed.
Heated spreaders provide a self-warming or heated blade to soften chilled butter, often in a cordless design offering up to about 100 minutes of use, plus ergonomic handles for controlled spreading.
Accessory bundles combine a butter keeper/spreader with serving items such as corn boats and often include a stainless-steel corn stripper for removing kernels.
