Ever kept using something past its lifespan because the dying feels like a conversation?

My bow hair has been splitting at the tip for weeks. I should rehair it, but there's something going on with the fraying — it feels like a dialogue, me and the hair, negotiating what it can still grasp before it gives up entirely. Do you have a tool or an object you keep past the point of sense, more out of attachment to the degradation than utility?
