Owner SSW CP - Up Eye
Owner SSW Cutting Point hooks are super sharp hooks that are designed to stick and penetrate easier than other hooks. They are have an offset hook point design to aid the hook in finding a sticking point, then the 3-edged Cutting Point penetrates easily for deeper, more solid hook sets.
The up eye version is popular in fly tying for articulated "stinger" style flies that are so popular in steelhead fishing.
Here is what Owner has to say about their Cutting Point hooks:
CUTTING POINT® HOOKS - Owner's revolutionary triple-edge CUTTING POINT® hook is what put the Owner name and its product line on the map. The unique, patented hook design is led by a needle sharp point, and as the hook begins to penetrate, the resistance actually decreases as the three edges cut their way through for an instant, positive hookset. While other hook manufacturers claim their hooks to be sharp, or sharpest, Owner CUTTING POINT® hooks are the only hooks designed to penetrate.
