I run an annual veterans hog tournament. So this year we bought some of these knives through the Amazon store. Well we cleaned 135 hogs . The knive blades would be done after 1 hog. I am sorry but that way to much money to skin one hog. 3 mano blades were dull straight out the package. We are cleaning 60 to 70 pigs a day. I b don't have time to mess around. Especially when I paid a lot of money on knives that don't work. Very disappointing!
