Review on Lansky HR1000 Ultra Curved Blade by Joseph Marshall

i don't know what material it was but the particles were flaking off like heavy scales all over my pants while i was sharpening and for 1000 grit i can't even fetch you a sharp razor edge for my karambit. Had to use a serrated sharpener to finish. I can't believe this is a Lansky product. I've had luck with 90% of their products but this one sucks.
