Hmm. Getting hit by the soft palm of a hand, or hit by a hard piece of metal traveling at the same speed. I bet that hard item would hurt more.
The comment was made "Less effective than a real weapon like a stick or club."
Well, I don't know about you folks, but a guy carrying a piece of rattan or hardwood looks suspicious. A "caveman" club more so. A modern club such as a baton, nightstick, etc, even more so, unless you're LEO. A flashlight is beneath the notice of most folks.
But, lets look at this another way.
What is "a stick"?
A length of hard wood or rattan. A tool to impart a blunt force impact to a target.
What is a "baton"?
See: truncheon: a short stout club
Ok, so both are simply hand held lengths of hard material, used to impart a blunt force impact to a target.
So, what is a flashlight?
Well, discounting the crap one finds at the dollar store, the average hand light is a short clublike object. Made of metal, it can withstand several impacts with a hard object. I'm thinking of Mag lights or similar. Not the K-Mart specials made out of cheap plastic.
Seems very similar to me, especially when in the hands of someone who knows how to utilize the tool.
The comments about the lack of effectiveness of pocket sticks and their ilk however reveals a lack of familiarity with the tool or it's uses. I don't carry pocket sticks, but I do buy solidly built pens. Those tend to get past security quite easily. But they don't teach the use of such objects in sport arts I've noticed.
