Have you ever laid your knife down when field dressing and then wasted time looking for it . I have but not anymore .
I carry a few of the red plastic flags that they have by the door at Lowes / Home depot and have them with my surgical gloves .I place one of the plastic flags on the ground and whenever it is necessary to put the blade down , I place it on the red plastic .
My SIL's ex-boyfriend lost his Case Knife one time and I had to take my metal detector down to find it ( under the gut pile ) .
