Fallkniven Flipstone: Revolutionary Sharpener?

I don’t know how long this has been out, but I just saw it yesterday. Not only does this sharpener look like a folding knife, but it’s a freaking automatic! I’m not great at freehand sharpening, but I might pick this up to give it a try. It might even be a fun, legal alternative for those of you in states where an automatic knife is not legal.

From the Fallkniven website:

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 whilst the ceramic is made of synthetic Sapphires. 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.”

(Editor’s note: I included the video from Bushcraft Canada – To show you the tool in a non-copyright sensitive way. Bushcraft Canada is a reputable site for bushcraft tools and outdoor clothing. I have ordered from them before and they are a solid company that is used to exporting (not Hultafors axes unfortunately) items to the USA.)

    I’d by it just for using “whilst” in the description. Who says our language is in decline!
