How to Use a Diving

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


Steps:

1. Choose a knife with a sharp, serrated edge. Cutting and sawing may be necessary. (Image 1)

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. (Image 2)

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. (Image 3)

Tips:

If you choose to strap the knife on the outside of your upper arm, be sure you regularly remove your BC using a shoulder-snap release. Otherwise, in case of an emergency, the BC vest will catch on your knife as you slip it off.

Warnings:
Never harm marine life unless you have purchased a harvesting permit for legal gathering. This applies to prying anemones, starfish and urchins from rocks, and cutting coral or kelp.

Do not watch "Thunderball" before scuba diving.
