I put the same nap sling blade through 4 deer, sharpened blades and put back in quiver. The deer I shot this year hit opposite shoulder and finally bent the blades. It would still work but I retired it. I always spin them and check sharpness, if good they go back in quiver.
Well I watch 5 deer walk towards my truck in the field right at sunset, yup sniffing my back bumper. They stood 30 yards from me as I got in the truck and drove away.
I think my buddy has a photo of me sleeping, we were sitting on a gas line and he was about 200 yards down, light snow, i was sitting up against a pine tree after a 8 hours night shift. when i woke up he was laughing his ass off.
