Diving knives are excellent tools, have very strong blades as well as being sharp.
If your worried about parents etc. feeling threatened by the sight of the knife and call security on you. You may ask yourself is the knife longer than it need be?
Sometimes the length will scare people, they watched too many horror movies. People who cook wouldn't give it another thought.
I have been using several knives over the past 40 years, still have my original digging knife that I still use today. It does have to visit the bench grinder soon.
It is a legal size to carry knife, wooden handle and balances very well. I have a trick that makes it almost impossible for anyone to notice your carrying a knife.
I have never been bothered about it. When detecting it it's easy to hold in the position pictured, it's out of view. When it comes time to use it, you let the blade
naturally rotate downward while holding the handle into gripping position. You do this as you kneel to the ground. When you retrieved your target, pick up the knife
and rotate it back into concealment position as you get back up. After while using this technique, it becomes very easy and automatic. By the way there is no
chance that the knife point will poke your forearm as your wrist will not bend inward enough to allow it to. Now this is also a great technique when hunting
and some undesirables walk your way. When they see that knife quickly rotate into position........
