This may seem like a no brainer and may have already been covered in the forum. The pm2 will not clamp correctly in the worksharp precision adjust sharpener because of the blades graduated spine. There is an easy solution that took me about six months realize. Remove the blade from the knife and clamp it directly over the spyder hole. This area of the spine is perfectly flat and the clamp will not tilt the blade downward when you tighten it. Instead it will be parallel and your chosen angle will be true. I finally achieved a perfect 15 degree angle that is nearly identical to what the factory edge was.
Hope this helps anyone who has been struggling with this particular sharpening system.
