Has anyone heard of or used the Speedy Sharp Sharpener, www.speedysharp.net? I pick one up at a Sports Show and it seems to work pretty well. The only thing I wondering about is how to get the agnle exact? Basically, its a metal rod with a Carbide surface at the front. You pass the carbide surface along the edge of the blade to sharpen. Following is an excerpt form their website: "Speedy Sharp Knife sharpener is the most universal sharpener ever made. It is durable, compact and best of all it fits in your pocket. It is made of MICRO 100 Super Carbide and will never wear out. Speedy Sharp is made in the USA. Run your blade across the super hard carbide steel edge only a couple of times and your knife is sharpened. It amazed us when we tried it, it will amaze you too."
