Asked this in the whetstone thread but here it goes since I didnt get any answers.
I have seen some people shilling this necklace as a easy in the field knife sharpener. Is it worth it to have something like this or is it a meme/overated piece of gear. Seems like a neat concept but I wanted to ask /out/'s opinion before I made my decision.
