I agree with the others, the slick trick does the job! I have taken 16 deer with one head, all pas thru's. I would still be shooting it but after going through the buck it stuck deep into a tree root and I couldn't get it out. The one I am using now has taken 4 does and 5 bucks, and still ready for more. I just clean and sharpen. If the blades go bad you can get replacements. I don't take picture of the gore, but one of the bucks shot this year went 10yds with blood everywhere. I have had complete pas thru in a spine shot.
