+1 Always worth remebering.As far as any knife for a defensive weapon, that will depend on your ability to use one. Cost, manufacturer, length or edge will be secondary.
I claim no superior skill in fighting with one, but have extensive training in removing one from you. Can you tell on sight who else may be similarly trained, and do you want that person facing YOU with YOUR knife? Bear in mind, if he got it away from you, what else has he been trained to do?
If you were indeed trained in the defensive use of a knife, you would not be asking questions about the viability of any knife for defensive use. You would use what you train with.
If you truly feel the need to carry a defensive weapon, get one that will deal with all comers.
I offer this with all due respect. Please read nothing more into this than there is a greater possibility of making a bad situation worse by entering into a conflict with the wrong weapon and no training.
Titanium chop sticks are great for airplane travel. They are sold at very high end Japanese shops. They run about $80 instead of $300+ some knife shops would charge you for similar tools. Since they are chop sticks, they are good to go. The packaging is fancy bambo.http://www.coldsteel.com/nightshadeseries.html
It's their series of polymer "blades".
They aren't really knives per se but more like force compliance tools and something that can be jabbed into soft parts of douchebag's bodies.
As I said earlier, not my first choice but better than nothing at all.
For an EDC last ditch weapon they would work well or for carrying on a plane (I beleive plastic blades are legal to carry on planes but check for yourself first!) or in similar NPE's.
this might be a better choice for carry ona plane though. jammed into a temple or eye socket this will ruin Goofy's day.
Good idea... a bit too rich for my blood though. hahaTitanium chop sticks are great for airplane travel. They are sold at very high end Japanese shops.
