Lol, you sure do know how to ramble and confuse.  I think it may be a subtle ploy to patronise and disguise it.  In fact, not-so-subtle ploy.
 But there probably is a sling in your ancestry - I mean obviously not in your immediate ancestry, that would be plain weird - but I am sure that someone in your family must have used a sling-like weapon at some stage, be it an atlatl, sling, or a sling-ancestor such as a bolas.  Not that this has made a definite mark on your sub-concious.  Not that it hasn't, though.
  What an odd line of conversation to go down.

English, TechStuff, ......now, now, play nice, kids.  mgreenfield

I fear I may have to swear.  Techstuf, you republican, conservative, patronising, overbearing crank:  "Grow up a bit lad".  I am six feet tall.  If I grow anymore, I shall be considered a giant.   Quote:

"Thoughtless blathering" indeed.  Although I would say that talking about Japanese conduct in the Second World War would come under that particular.  Do not believe that you lessen the impact of words if they come with a wink.  It merely serves to make them more patronising, and, if I may say so, and even if I may not, tiring.
  Anyway, with regard to Japanese slings:  I would imagine that, had Japanese slings existed and been used more often, they would be most excellent quality, and braided no doubt - we all know of Japanese braiding techniques, and the skill and importance they applied to all their martial implements, so it would therefore be probable that a Japanese sling might have been a thing of excellent sling technology.  Pity they did not.

Duke it out by email guys, not in the forum please.

None.  At least that I could find.  Back in my 'glory' days as a martial arts practioner,  I searched diligently but could find not a single reference to slings or even a close derivative used in Japan.  This of course, is not to discount the possibilty that they may have seen limited use perhaps among Okinawan farmers who became quite adept at ultra utilitarian weapon concepts.    I demonstrated various quick draw and power slinging concepts at our Dojo to highlight the superiority of the sling over myriad Japanese fighting implements.....not a single taker.  Although the whole premise of Ninjutsu was....(and presumably still is?) to scavenge from the best wherever it is found so as not to limit oneself, curiously, the sling is a strange animal to most people.   Seems there is no middle ground for the sling at large.  One either 'gets it' or doesn't.   Japan never 'got it'.....although I prefer to consider that she just never had the opportunity.

10 years o' fightin' here, and nary a sling in sight.  Of course, most of my training has been in styles that don't use many weapons, but still...  I've never even heard of slings in the Chinese or Filipino systems, and between the two of them they cover just about every pre-firearm weapon imaginable.

Did you make those Tech? Wow!- you've got us all beat in weapons manufacturing!!

Johnny,  although we do much of our own prototyping in house,  I did not make these shaken.   I have found that the Chinese can blow me out of the water when it comes to cost of production.  I get these from china by the crate for $2.00 apiece!  I couldn't begin to produce my own of this quality for anywhere near that price.   I will try and get some pics up of what can be accomplished with these shaken and my 18" thrower.......I would almost certainly be accused of photo manipulation after one sees the penetration results.  8)
