Why do you not use the same blade on two hogs? and why do you toss when done?
The blade is usually getting dull by the time one hog is finished, so he uses the unused side for the next hog. The blades he is using are disposable.
I use a Cold Steel Master Hunter for cleaning and skinning. With the hog hanging by its back legs, I start skinning the back legs until I have enough loose skin to grab with my hands. Then I start pulling. Have to cut a little around the front legs, but I pull the majority of the skin.
