Query: Only good for kitchen knives

The way it works, it pulls your blade through. This sounds good in theory, but I had a hard time controlling it. For me, it took off too much metal and it was difficult to get the curved part sharp (hunting knife with more curve then the average kitchen knife). For pocket knives or any blade with a guard, I found hard to get them close enough to sharpen the entire blade. I would give it 4 stars if it had a disclaimer that it only works well with kitchen knives. Maybe that is supposed to implied as it says Chef's Choice, so I give it 2 stars instead of 1.
