I would love to see a knife maker try this out.

It would lower the overall weight of the knife...but still give good momentum to the knife for manipulation.

Any forum members think they could try to draw some designs??

The weights would have to be designed so that you can't touch them from the outside of the handles....otherwise your fingers would stop them from sliding....

In think it would be the best of all worlds....not to heavy of a knife...so that you could carry it everday......but still have good momentum for manipulation.

I would like to see a 3.8" blade....as 4" blades are illegal to carry in NYC.

I live on Long Island where the 4" rule doesn't apply...but I often go to NYC and would be a hassle to switch between knives. I love my BM42 but I find it annoying to have to carry my folder when I know I'm gonna be goin to NYC.
 
There's been talk of adjustable weights that could be screwed into a 'skeletonized' handle to vary the momentum but sliding weights....... What would happen when a ricochet is performed and the weight is going one direction and the handle suddenly goes the other? Would the movement be fouled or suppressed? Just wondering.....:confused:
 
I think the weights would have to be computer controlled much like our modern fighter aircraft, which are otherwise unstable. Think of the possibilities, the ultimate aerial, finger twirls with simultaneous twists...
Just kidding, sliding weights are an interesting idea.

Sorry Dan, any size bali are illegal in NYC, even the latchless ones. :(

As for sliding balis, one thing is for sure. It'll be real hard to do with a channel milled handles. But with sandwich bali's it would be easier. Using the Tachyon as an example, I can think of two approaches. 1) Replacable inserts. Using different material and mass, in increments of x grams. Keep trying replacing them until you find the one that suits you. 2) Instead of dedicated drilled holes for the insert screws, drill a slot that allows you to slide the insert up or down until you find the proper weight distribution. Of course this means MT will have to come up with another latchgate. ;)

Do you have documentation that shows thins....I was under the impression that in New York state the balisong wasn't considered a gravity knife...and therefore legal.

In certain parts of New York State, that is true, and there is a case law decision that supports this. However, NYC Criminal code did not follow suit, and still considers the bali a gravity knife, ergo not a legal carrying knife. Worse, the NYC code's supercede the NY State statutes.
 
AAaaarrrgggg

So that means....no bali's in Queens either.....Doh.....Now im mad...
 
Alright, before you start digging into me about all the obvious mechanical problems :), let me say that this was just to show my idea. The weight is inside the handle and is adjusted up and down by turning the torx screw. The more I look at it, the more it seems that it wouldn't work (not really enough room in the handles), but maybe it could be improved by one of our resident engineers.

Good idea but if the weight could be moved via a threaded rod that means the handles are hollow. If thats the case the knife is going to produce very little potential energy which I thought was the idea. Granted the moment arm would be larger in relation to the center of gravity...... Also the center of gravity could be changed to suit personal preference.
 
Hi Dave :) ...just a dumb question.., but what view am I looking at on your mock-up?? Is that a Top View looking down into one of the blade channels??

Thanks...

Well, I suppose it's looking down on the inside channel. The torx head is at the end of the handle. It's missing some parts for sake of simplicity and explination. The weight has grooves that slide along some "rails". I'm not quite sure where you could fit this inside of the handles, but I was hoping someone else could figure that out.
 
Get 4 tubes, and put a little lead or brass chunk in each one. Then put one of the tubes in each of the milled slots for the inserts on each side of each handle.
Or make a U shaped weight that slides in the U shaped hollow handle. I'll let you figure out how to make a U shaped hollow handle.

How about using the whole channel wall to act as the rail. You device can ride the groove where the wall use to be, with the groove for the rail cut into the handles in the same location. It'll need to be done as a sandwich construction bali, and the latchgate/hand end will have to be very strong to prevent handle flexing. But there's no reason why you can't simply replace the 1/8" material that use to constitute the channel wall with that contraption. Of course you'l have to thicken the handles a bit to compensate for the materials removed.

For the timing advance models, we've got a problem. The balisong can be manipulated any which way. So, in most positions where the floating weight can be distributed in a fashion that flows with gravity, it'll work fine. Anytime the bali is manipulated against gravity, you'll going to be really screwing up the balance. One reason the adjustable weight needs to be "fixed" in position.
