I shot a doe and hit her a little high. Dropped her in her tracks and she kicked a little and that was it. Cut the main artery and caught the backbone. I pulled the arrow out and the blades were intact with very little damage to the edge. Took a steel and went across the edge a couple of times and it was back to razor sharp. I replaced the "O" ring and salvaged the collar so I'm going to use it for hogs.
