A bent dart point can be hugely annoying, but the good news is it does not mean your beloved darts are unable to be used again. Much like flights and shafts, steel tip points are an interchangeable part of a dart and can be replaced.
A broken shaft is in most cases a relatively easy fix. The good news is, shafts and flights are disposable items on darts so they can be replaced easily at relatively low cost. While it's an irritation, it's all part of the game.
