• Ultimate Fret Crown Optimizer UFO can help restore the crown as close as the original shape in minimal strokes.
  • Conventional ”stick” type crown file seemingly contacts the fret lengthwise, but because most fingerboards are curved, 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 transmit power straight to the spot. So at least you know where you want to sand visually.
  • You may have been dressing fret summits with straight files, somehow trusting your instinct and experience with a detailed view that might have left corners unrounded or ruined the arch. However, UFO can tell you are simultaneously making the crown in 3 aspects: height, width & curve. So, filing an object with a convex surface with a concave tool does make sense.
  • Radius: 1.5mm, 1.6mm, 1.7mm, and 1.8mm. Size: 50mm diameter x 7mm thick. Weight: 95g. Material: Steel in Nickel-plated.
  • Disk design: Palm size, easy to hold, control, and see the filing point.
  • Concave file with 600 grit diamond: For fast and easy crowning. Made in Japan.
