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).

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.

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.

looks good. the blades will be a little brittle, but should work. well done

So how do you make the knife lock.
Jul 5, 2010. 3:44 PMdawsonj says:
when the top of the hacksaw blade hits the inside of the pvc it stops it from sliding more, but id doesn't lock the other way

I like it. Nice work. I make mini neck knives out of hacksaw blades as well.
I use a simpler technique they are part of a necklace kit I make.
But I really like this. These are up to $5 and you just made one for free basically.

Strong work keep it up. Peace

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.

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??
Jan 30, 2007. 10:59 AMVendigroth says:
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
Jan 30, 2007. 8:12 AMVendigroth says:
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
Jun 11, 2007. 6:09 PMchemy999 says:

Nov 30, 2008. 7:27 PMxenongamer says:
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.

Nov 10, 2008. 11:56 AMpumpkinman says:
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?
Nov 7, 2008. 4:49 PMLance Mt. says:
Boiled water. It does the job rather than a naked flame with toxic fumes.. Other than that, It's super sweeeet (making 1 now.)
Oct 3, 2008. 1:15 PMnfsaggese says:
Do you know how to make it a locking blade?
Sep 13, 2008. 10:52 PMled_scorched says:

How do you pop-rivet? I need a substitute, any ideas?
Sep 12, 2008. 6:09 AMbob_shaftenkluger says:
Use a bolt?

how much does a pop rivet gun cost
Jul 5, 2010. 3:46 PMdawsonj says:
eh, about ten bucks
Aug 21, 2008. 6:24 PMDIYerr says:
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 balisong
Jul 6, 2008. 2:25 AMAnarchistAsian says:
nice instructable, but when you melt the plastic, be careful, the fumes coming off of it could kill you...
Jan 4, 2007. 4:32 PMstone3408 says:
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.
