I have one but I leave it in its plastic sheath and in the tool box. It's too gnarly to keep in my case.I'm a fan of my 4 way wood rasp it won't ever wear out , it's big enough it doesn't get lost or forgotten and I wrap it with a handkerchief and it stores neatly in my cue case .
A few taps to the tip of my cue and it's done .
