We knew that…
Best wishes.

I thought that was common knowledge? In fact, I always thought that the bodhrán was developed as protection against flute attacks?
luckily the OP had chosen a venue that will not spread that knowledge much 
There are things that outsiders do not need to know…
That explains why when I bring out my flute people start running!
Aye, but what key’s it in ? And would it be any good against the Glasgow martial art of “F#k Yoo Too” ?
Wasn’t there a “ninja” flute posted up here a few years ago ? I’m sure someone could find it.
sigh he’s so easy…
I was under the impression that the reason Shakuhachi were traditionally made from the root end of bamboo was because it was extremely tough, which allowed the flute to be used as a weapon in a pinch by the wandering “Priests of Nothingness” following the banning of carrying swords in Japan.
Not sure I’d want to beat someone over the head with a well made Shakuhachi mind - those things are expensive, whereas skull x-rays are cheap…
[nitpick] That bad boy may have spent time in Japan, but it ain’t no way Japanese. Also, its pointy bit is no defensive weapon: you have to take the time to unscrew the cap. “What? You’re mugging me? Hold on just a bit, would you?” fiddle fiddle [/nitpick]
Who says it’s always fun to kill people fast?
Not me!
Like I said, it’s no defensive weapon, pointy-wise. You can take the time to get it apart and then go off to poke holes in people, but if you’re being surprised, odds are you’re left with just your basic stick-type object unless you’re good at evading getting clocked while you unscrew it. Too complicated for when you’re idly out and about the town.
yeah, ah, whatever, eh
An educational opportunity, and this is what I get for my pains? Ingrate.
Since you obviously haven’t had enough, I’ll also point out that a threaded endcap like that is a direct inheritance of Western tech influences. No self-respecting actual ninja-ish type would have designed it so. At most it should disengage with a simple twist and pull. So, strictly speaking, it’s a mono-tasker: for offense only, and at one’s sinister leisure. Not very sporting in its concept, if you ask me. Pretty, though.
five & a half years latter?
I don’t suppose ya could be just a little more timely?
'sides, fuss at Jon 
and one o’ these;
(You’ll note the socket type handle.)
Or just go modern and carry a Glock.
Guys the book clearly states that you need no knife to make a flute a deadly weapon… And we already knew that all you need to do to make you enemies flee is to play it.
Right. We have our guyness to thank for an adolescent fascination with hidden bladelike appurtenances. It’s like flames painted on a street rod: arresting to look at, but it doesn’t help the car drive any better.
This is the pinnacle of mastery. Go forth and teach.
Okay, so I’m bored.
BTW, that one-piece socket-handled knife-cum-spearhead? I know it as a nagasa, standard issue for your mountain Japanese bear hunters (matagi), a uniquely distinct subculture that’s almost all but died out. In that country the nagasa is traditionally specific to them, but I’m sure other cultures in the world have come up with the same idea all on their own, too; it just makes that kind of sense. Great general concept, but seems to me the smooth handle could get pretty slippery during non-spearish use. You know what I mean.
I think the handle could use some knurling, but nothing heavy. Yeah, that’s it.
Okay, so I’m jealous
So you want to be bored, do you…? Well, I thought I was all there for you, but I can definitely keep accommodating. And accommodating. Noooooo problemo. 
Hey, here’s more deadly flute stuff.
The Flutes of Death line dance:
“Deadly flute gun.” Apparently this is legit, if possibly ill-conceived.
And how cool is this:
