It is an okay tool. I do not use it much anymore, as skis became wider, the old model became tighter tip and tail, though you can buy a longer steel. It is important to keep the steel sharp. Works better for base high than edge high. One needs a good vise that does not slip as you need to use decent pressure as you work the tool. Anymore I use Silicon Carbide sandpaper for flattening and structuring (initially).
