The shape of Knapek hooks with the famous Knapek barbless points which are super sharp make them a popular choice. Their Achilles heel is the eye, which I find aren't always fully closed, on balance I still think they are worth using for shape, hooking power, strength and sharpness.

Good with slotted beads for jigs that don't snag the bottom as easily.
