Hi all. I received a Work Sharp for Christmas and had very high hopes for it considering I suck at sharpening. I was able to put a razor edge on my Tops BOB which is 3/16" thick, but can't get my Izula 2 (5/32") or pocket knives to even cut paper. The right side of the belt seems to have much more give to it than the left, and as a result the left side of my knives are sharpened higher up the blade than the right. I noticed that when using the right side of the machine (sharpening left side of blade), the blade will completely slip down the belt inside the guard once I get toward the tip. Basically my question is, do you guys notice a difference when using the left and right side of the machine? Is this just an issue with my technique or is this model defective?
