Retractable diamond sharpening rod Serrated knife sharpener Household tools Mini grinding rod Outdoor hunting multi-tool Jungle tools

A great value, and well made. The cutting end was secured firmly in the handle. There was no perceptible wobble. It will likely last me a lifetime of occasional use unless I lose it or do something reckless and irresponsible, and it’s inexpensive enough that I could conceivably use it that way.As the description says, it’s 400 grit. If you are familiar with flat stones, this is VERY coarse. Think of it more like a file, not a hone. It will remove a lot of metal very quickly and it leaves deep scratches — even with very light strokes because the force is concentrated on a very small contact area. If scratches bother you and you’re not willing to spend a lot of time cleaning it up with finer grit rods, don’t use this on your favorite pocket folder.In my case I needed it to repair the rolled apex on a cheap serrated kitchen knife that we’ve been using to cut frozen foods for 15 years. It served that role admirably. That kitchen knife is now back to cutting as well as it ever did.The tool is conveniently small and very versatile. The tapered end of the tool allowed me to get into the smaller serrations, the half-round end worked well on the larger serrations, and the flat side smoothed off the burrs on the other side of the blade. The half-round end has a long groove that could be used to sharpen the point on fish hooks.If you are planning to carry this tool using the pocket clip, be aware that the diamond rod does not retract completely. You’ll need to find some kind of cap to cover the exposed nub to prevent it from scratching other gear of abrading a hole in your pack or pocket. It did come with a clear plastic “zip lock” sheath that would be an adequate cover to stow the sharpener in something like a tackle box.
