documenting the many uses for the common pocket knife
While up north this summer I did a fair amount of unsuccessful fishing and therefore had ample opportunity to use and drop into the water my trusty pocket knife. Thankfully I only did the latter a couple times and was able to retrieve it each time, the other opportunities including fastening weights onto fishing lines. I would use the blunt attachments or even the knife itself on a rock to squish the lead (are they lead?) weights onto the line sufficiently so they would not fall into the water or fly off and hit someone in the eye.
