-Terry there is a minimum angle where the stones will collide with the vise for every knife. The size and height of the knife above the vise jaw line effects this. Taller and larger knives are less of an issue then smaller shorter knives. The knife does not need to be clamped in the vise so it rests on the positioning key posts. That is not a necessity. The knife can be raised higher up in the jaws, when need be. All that matters is that the knife is securely held in the jaws so you can sharpen it. None-the-less not every knife will work in the W.E. sharpener. Some are just too small or short. At some point you will need to utilize an adapter. Either the W.E. Low Angle Adapter, LAA, or a Tormek Small Knife adapter. There are other modifications that may help also. The other alternative is to increase the intended bevel angle to an angle where the stones don’t contact the jaws any longer.
The issue may be more evident on one side of the knife then the other. Even if the knife was centered. Every knife has a minimum angle where this issue will be evident.
