Cuetec Tip Prep Tool 2 in 1 tool that is a pocket chalker and tip aerator in one.
Aerator – The purpose of the aerator feature is to slightly break up the surface of the tip when it is new or it has been compressed after being used for a while. You must unscrew the tool to reveal the aerator pins. Gently roll the aerator over the tip, piercing the tip with small pin holes so it will hold more chalk. Do not twirl, twist, or scrape the tip using the aerator. You will tear the tip to shreds if you do. You can then also shape and/or scuff after that.
