Funny knife story. About 10 years ago I was diving the Tacoma area just on the other side of the Tacoma Narrows Bridge. I was out with my dive club at a new location. We were diving from a park that provided access to a beautiful part of the Lower Pudget Sound. Anyway, after my dive I came up about 100 yards down the beach. Great! a long walk with all that gear. Anyway, I'm walking down the beach with my perscription mask around my neck and my ears full of water. Next thing I know, this guy is 3 inches in front of me yelling at the top of his lungs that I am on "His" beach. He goes away for a minute and comes back with a big boat pole. I dropped my goodie bag that had my fins in it, planted my feet like a Suma wrestler and pulled out my monster dive knife. I don't use it much under water but it has its purposes on the surface. They guy ran away and I went on to the park and put away my dive gear.
