Flipstone® sharpener - Opens like an automatic knife

Never before has it been such a pleasure to sharpen your knife! Not only are the new Flipstones fun to handle but these diamond and ceramic whetstones will create a sharp edge on any knife. The diamond stone is coated with Titanium Alumina Nitride (25 micron or 800 grit) whilst the ceramic is made of synthetic Sapphires (1 micron or 14,000 grit).

Both materials are extremely hard and measure 10 and 8 on the Mohs scales of hardness respectively. They will also retain a smooth, flat surface making the sharpening process easier, even with the hardest specialty powder steels. Both stones are sandwiched together using 3M tape and cannot come apart. They are used dry, although a little soap and water can be used to clean the surface. If they feel slightly rough at first they will gradually smooth down and actually improve with age.

Instructions: Hold the flipstone in your left hand. Release the safety on the upper section of the handle forward and press the button. The whetstone will automatically spring out and lock into position. To retract, press the button and collapse the stone by hand.
