The Whetstone Sharpener Helper/Sharpening Guide is designed for a 180 x 60 x 15mm whetstone, which solves the problem of slippage from the original design. This device sharpens at an angle of 16 degrees, resulting in a razor sharp tip. Use this with caution!
It was tried with my Japanese knife and I was surprised by the result. For many years I have sharpened my knives without tools and have never achieved a good cutting angle. This device did it on the first try!
I was worried that plastic to plastic wouldn't slide well. After testing, I can confirm that this is not the case. When wet with water, it is very smooth and therefore does not pose a problem.
