The Ultimate Fret crown Optimizer (UFO) can help you restore the crown as close as the original shape in minimal strokes.

For those aiming at more accurate crown shape, UFO would be the first choice to take.

Conventional ”stick” type crown file seemingly contacts frets lengthwise, but, due to the fact most fingerboards are with curve, it touches the fret at one point without even knowing where you are sanding at.

This UFO, a palm size disk, with the point of effort and load aligned, can transmits power straight right at the spot, at least you know where you want to sand visually.

To widen the field of work, having both UFO 1 & UFO 2 would be highly recommended so that you could handle broad range of frets.
