Thread: About cheap syntheric

Edit: Synthetic!!

Hey guys, there's something i have wondered every time i see it, maybe someone here knows the answer.

I have a few nice easy cheap hones that i use mainly for knives. After use, maybe a day later, when i look at them, one or two of them have a strange H type drying pattern as if there are hollow portions of the hone.

kinda looks like the two big rectangles may hollow or something. Any guesses or knowledge?

thanks
