How to Remove a Lung Lobe in an Animal?

i like to aim in that vital v close to the top of the heart lung area because, you know, it's risky. Bcause there's bones around, but if you got the right broadead, you can get through the bone. In a really sharp cut on contact two blade verss, like a three point free blade chisel point, there'll be about a five times difference in force t go through. But what i see on the cheaper steels is that if i repeated the test, push through, hide and hide muscle again, the force is going way up. So they dulled quickly, and we're pushing more stuff aside.
