Two years ago I left an Ingram by a creek while dressing a deer. I'd washed it in the creek after dressing the deer and set it on a rock to let it dry while I got my stuff together before heading out. Realized I'd forgotten to get it after I got home and went to process the buck. Called a friend that I knew was going to hunt the area the next day and told him where it was. He grabbed it on his way out. It was a yellow G10 handled knife so he said it was easy to see.
Many years ago I was dressing a buck in grass and set a green canvas micarta handled Dozier down in the grass while I re-positioned the deer. No joke, I bet it took me 15 minutes to find the knife again. From then on most of the knives I've ordered have been either orange G10, yellow G10 or blue G10 for hunting knives....anything aside from those colors I put orange beads on the lanyard.
