The Gold Multi Functional Cue Tip Trimmer tip is five tools in one! Sharp metal teeth tap chalk into the cue tip, and can also be used to scuff a badly glazed tip.
The shaper shapes and scuffs the tip to a dime or a nickel radius.
The trimmer trims the cue tip to within 0.010" of flush with the ferrule.
The burnisher hardens and polishes the cue tip sides exactly flush with the ferrule.
The abrasives are replaceable!
It will improves your game by giving you a consistently solid hit. They call it "The Best Cue Tip Tool in the Known Universe", but NASA has evidence to show that it is the best tip tool in other universes as well.
