Unlike James Bond in "Thunderball," a scuba diver uses his knife as a tool - not for cutting the air hoses of his underwater enemies.

Instructions

    • 1

      Choose a knife with a sharp, serrated edge. Cutting and sawing may be necessary.

    • 2

      Use a knife with a flat head. This is an excellent tool for adjusting gauges, and it eliminates any worry of stabbing something - such as your diving buddy.

    • 3

      Employ the pry notch and ruler along the knife's edge to harvest shellfish and measure crab. Remember that light refraction can make that small shell look huge.

    • 4

      Select a knife with a hard disc pommel end that can be used for hammering.

    • 5

      Strap the knife sheath on the inside of the lower leg or thigh. Veteran divers call a knife strapped on the outside of your leg a "kelp catcher." It doesn't take a lot of imagination to understand why.
