Please don't capitalize every word. It gets annoying. Keep in mind that butterfly knives are illegal in some areas without proper documentation. I don't think it would be too hard to take the blade out of an existing knife, then modify it into a butterfly knife.
I got 2 that I made, check mine. the handles are made from sharpie pens that conceal the blade when its closed. Its awesome

kinda moves fast but a very good and solid project. I'm going to ask him to post it on instructables.

There's a lot of resources out there, I'm hoping to make one myself sometime. =)

The tools you'll need are mainly material which can and old circular saw blade, or an old file...
-A hacksaw
-File, two different types is good.
-A Vice, or other device to hold the work.

Google is of course, a friend.

Here are a few links:

http://www.knifehow.com/knifehow.php this is a great resource site for knife material, but unfortunately it doesn't seem to be moderated, all the links past page 8 or so are crap.

and, http://dremeltingpotes.ifrance.com/SHORT/creation/nanobali4/Tutorial%20English.pdf (BEWARE, it's a .pdf)
...the main site is: http://dremeltingpotes.ifrance.com/

Btw, you may need to take a few tries to make it decent. ;-)

Looking at the first link, am I missing something or, when he has the knife closed, could you still move the handles up/down relative to one another and have a bit of cutting edge sticking out the side? That strikes me as bad if you're going to do things like put it in a pocket and then reach in the pocket to remove it.

no, they do have to pins, one above the pivots, and one below, it stops the handles from flinging too far, and jiggling up and down. Like this:

oops, I didn't mention, you'll also need a drill, a fixed Pillar drill is best, and also a (coal) fire or gas for tempering the blade (+ oil)

(Please stop capitalising every word - it is rather annoying to read.) First, obtain your butterfly. The larger the better, so try and get hold of a birdwing or one of the larger swallowtails. Second, apply an edge. A blunt knife is worse than useless. There is a lot of choice, and even more discussion, about how much of the wing's edge should be sharpened. Some "extreme" types sharpen the whole wing-set, but really this can cause more problems that is solves, as it reduces the number of options you have for gripping the knife. Unless you are planning on spending significant amounts of time in close melee situations, I would recommend just sharpening the front wings. Actually applying the edge is a relatively simple affair - stroke the wing gently at a low angle across some 1600-grit wet-and-dry abrasive paper until a clear edge is visible, and finish off with a traditional oil-stone. Half-an-hour's careful attention can produce an edge that will shave mahogany. Once you have applied the edge, maintenance is a relatively simple affair - just give the edge a quick strop with a barber's leather after heavy use, and give the butterfly itself a few drops of sugared water four times a day, five in hot weather. If you stick to these simple guidelines, your butterfly knife will give you many year's service and be the envy of all your friends.

Leather strops are rather hard to find nowadays aren't they ? :-)

Not half as difficult as catching the butterfly in the first place - why do you think so few people carry them these days?
