Make A Two Bladed Folding Pocket Knife Made From PVC & Hacksaw Blade.

Step 1: Parts and tools needed

To make a Two Bladed Folding Pocket Knife you will need 1/2 " pop rivet, 2 washers, and "thin wall" Class 200 PVC . Time to make about 1/2 hour. Tools needed are hack saw, pop rivet gun, stove, sand paper, grinder (you can use a sharping stone rather than a grinder but it takes longer).
pretty cool r u going to put ur name into the side contact me back
Thats is awesome. sadly i dont have all the tools to make it :(
Seems to me like the pvc would wear and let the blades wobble around and fall shut. I wonder if you could use one of those spring washers between the blades. that seems like it would keep them the right tightness even when the thing wears a bit.
Thank you, I appreciate these sorts of projects and the nice layout that is step by step.
awsome <br>dude <br>
If you arrange the saw blade so that it cuts on the pull stroke, rather than the push stroke like normal, it'll help prevent the blade from breaking.
hey yeah....like a japanese hand saw!
seems pretty awesome, although i have tried making knives from hacksaw blades and they always snap. i would try this, but use old reciprocating saw blades.
I bought a brand shoes. Cheap and beautiful. In fashionclpumps.com
looks good. the blades will be a little brittle, but should work. well done
extraordinarily good!
looks pretty cool and easy. Might have to try it when i get some time!
have you tryed meccano for the handle?
Nice Instructions. very clear and precise. 2 bladed folding knife is very handy. i was thnking of making one with 2 saw blades. thanks for sharing<br /> <br /> <a href="http://springassistedknives.net" rel="nofollow"><strong>Spring Assisted Knives</strong></a><br />
I like it. Nice work. I make mini neck knives out of hacksaw blades as well.<br /> I use a simpler technique they are part of a necklace kit I make. <br /> But I really like this. These are up to $5 and you just made one for free basically.<br /> <br /> Strong work keep it up. Peace<br /> <br />
So how do you make the knife lock.
i made a few of these knives today i made one like the one in the picture but with a sharp point rather than a rounded one i also made a single bladed version (also sharp pointed) and then i made a folding fillet knife but with the same materials! i not only made the point on the blade but i polished the blade with a belt sander and then fie sand paper and it looks really professional! thank you so much for the idea by the way!
if you have access to a laser cutter, you can make the sided bits on 2D Design
Does the knife stay open or is it loose and fall back into the handle? Thanks and great Instructable.
How do you pop-rivet? I need a substitute, any ideas?
Pop-rivets are small metal rivets that require a "Pop-rivet tool" to make it work. You can get both at most hardware stores. You can also use regular copper rivets which use a hammer to mash the protruding end.
how much does a pop rivet gun cost
Use a bolt?
I'm in the process of making a metal version of one of these, but I realized that the knives will dull when they contact the metal over and over. What can I use to cusion them? I was thining of this rubber coating stuff, but I don't know what it is called and where to get it. help please?!
y dont u use inner tube??
er....try a little bit of papre, just folded and pushed into the handle, if that doesn't work try and get some thin leather or a piece of the sealing rubber off waterproof torches. or even an elastic band poked into the bit where the knife'd touch the metal
take a swiss and cut off all but 2 blades
or just take a swiss
i know i should leave you alone, but i just realised as i got home from college that if you use copper as the metal, the steel'd not be damaged cos the copper's softer
good. I might try this, seeing as my other knife got... broken... while i was trying to modify it. yeah, who knew that tungsten could destroy half the house.</joke>
i like the style i made one sorta like it expet was an otf swicth
and i mean the par were u bind the pvc
its realy cool but how do u get it to fold
extremly nice instructable, i used boilin water to bend my pvc pipe and that did not work so well. do you have any idea of what to make of the rest of the hack saw blade?
Boiled water. It does the job rather than a naked flame with toxic fumes.. Other than that, It's super sweeeet (making 1 now.)
Do you know how to make it a locking blade?
very cool.. if i had more time, i would totally try this!
This is an exellent instructable. I am using the pvc material and method described here as a substitute to a kydex sheath for a very small neck knife I just started making.
I am going to make a <a rel="nofollow" href="http://www.balisong.com/">balisong</a><br/>
nice instructable, but when you melt the plastic, be careful, the fumes coming off of it could kill you...
I diagree this could be very useful if produced without the knife (that could be a problem). Think screwdriver shape, lock pick, wire bending notch, or awl along wih the saw. I would even consider using jig saw blades, less grinding I will have to destroy some saw blades over this one. I wonder if you could wrap that all up in one sawsall blade sheath it and make it wallet worth.
like this...
Awesome!!! after seeing your other knife instructable i came up with the exact same idea but i didn't know what to use for a casinggreat instructable i rate 5 star! thx 4 posting -sk8erdude
