Those things are scary sharp and you can mess up if you aren't very careful. To me it's easier to cut thru the hide, and/or cut yourself. And, I do use a hemostat or needle nose pliers to change those blades.
Skinning a big hog with their thick, blade dulling hide, you may finish up with just one blade, maybe not. With WT's, not a problem. You may be able to skin a couple with one blade.
