The Nipper is a manual pebble nipping machine that was designed to make preparation time befor games quicker and easier. The Nipper was created as an alternative to 'rocking' stones up and down a sheet of ice. Instead of smashing the high tops of your pebble which occurs during 'rocking' The Nipper cleanly cuts the pebble giving you a more level pebble surface for your stones to run on. The Nipper can be adjusted easily using the knobs attached to each of the floating blades that do the nipping. Gliding easily over the surface its these floating blades that are the key to the success of the Nipper. Once the Nipper has been set to the desired height, there is no need to re-adjust it every time you use it.
