OK I know its not a gun but it is somewhat related....Being an old salt and a lifelong sailor I have a thing for always carrying a knife onboard (sorry guys for self preservation not self defense ). For most of my life I have carried standard folding rigging knives that have a blade, shackle key and marlin spike. I have always required all three in any knife I carried. As I get older I am feeling the need to keep one hand for myself on the boat which makes opening a folding knife a little tougher with only one hand available. If you have ever seen me stumbling across the rolling deck you would find it may be my weak or strong hand that is available....I recently found on Ebay what I thought was the ultimate fixed blade rigging knife, but it came with no sheath or Marlin spike. I decided to find a good spike and make my own sheath. Turned out to be pretty easy and I think it came out great. I made it for horizontal carry so it doesn't interfere with sitting (or falling..) and also tucks in pretty well to prevent getting snagged on something. Next up I have an old file I think I will try and make a knife from just so I can make another sheath!
