They handle bone as well as anything. The hollow ground 4 edge tip creates 4 stress fractures which blasts bone. I believe 5 Shot who tests broadheads through plywood said they made the biggest hole he had seen or something to that effect. That lets you know they work as planned as bone is more brittle than plywood. They also pass the steel drum test with no damage. So called cut on contact tips are good with traditional bows where you are trying to get a pass through the ribs, but with a compound you get better penetration through bone with the 4 edge tip since it shatters bone where a 2 edge tip just wedges. It is nice to have a chance to kill an animal going through the shoulder blade, but everybody should understand that is a bonus and not the percentage shot. You should use the accuracy of a head and the discipline of a good broadside or quartering shot to take out both lungs, and your odds of recovery are 99%. Nothing in bowhunting is certain. If you miss and hit the thinner weaker portions of the shoulder blade you have a decent chance of penetrating and getting both lungs. That is why the Slick Tricks are not larger than they are. They do plenty of damage and if you gut shoot one and let it alone for awhile it will bed down and expire. But the cut is not too big to hinder penetration through bone. However, if you hit the thicker portions or ridges of the shoulder blade just right no head will penetrate and you are out of luck. Thats why you aim to miss the shoulder blade. Rule #1 in bowhunting is take a good shot inside your accuracy range, hopefully at a relaxed animal. Hope that explains it a bit.
