I've had issues with cheaper clamping systems refusing to hold many blade shapes securely, but these have clamped every single knife I own so tightly I could likely drag or lift the entire system by the knife and they still would not switch. I can be tricky centering FFG knives but that's the nature of most clamps, and it can be fixed by using one clamp at the base of the blade.

I love the added length. These should have come standard on this RS sharpener. I will likely never use the short clamps again. It would have been nice if I hadn't needed to make my own rubber pads for the jaws of these clamps to avoid scratching my blades..
