Located on the side of the tool, the hook sharpener was probably the best feature. The sharpener is designed with a v-notch that cradles the hook point and makes the task much easier. About the only gripe here is that the surface area of the sharpener could be longer, but in this case that would mean a whole redesign of the housing. As it is, it works relatively well and gets the job done.

The hook sharpener was efficient, but could be bigger.

On the inside of the tool is a seemingly handy belt clip with a jig-eye cleaner that's built in. Unfortunately, the design of both really promotes frustration! The curved belt clip is quite difficult just to put on, and trying to wear it on an elastic waistband is basically a futile effort. In addition, it should be slightly longer so it grabs the belt or waistband more securely. Lastly, if you place your thumb on the top of the clip for added force when pushing it on, the jig-eye cleaner is right there and sticks into your finger—ouch!

This feature begs for a redesign!

The jig-eye cleaner was a bit of an oddity. While it should work to clear certain styles of larger jig eyes, it is useless on smaller eyes that are recessed into the head slightly, such as on every single one of my football jigs!   

Located on the bottom of the tool, the extendable line threader is a neat addition that works as advertised. The long, thin wire extends out from the housing via a thumb-operated slide mechanism and features a tiny hook on the end. This is very handy for threading line through a casting reel levelwind as well as picking out a dreaded backlash.

This is a creative feature, however I still would rather just use my fingers.

Take notice of how the right (bottom in the picture) side of the jaws is blocked off by the lanyard eyelet.
