Are you filmakers out there wanting to incorporate a knife fight in your action films but don't want to put your actors in danger? You could dull a knife but that still presents risks AND up close shots can reveal the knife's true edge. Quit stressing out and look no further! Today I will show you how to create a prop knife in under half an hour (excluding paint drying). I have also created this instructable in  a way that will keep you from having to take trips to the store. It uses no advanced tools. Just objects you can find around your house! I in no way have copied this idea from anyone. I was just a filmmaker that wanted a knife to use without putting my actors in danger.

DISCLAIMER: I in no way am responsible for what you do with this fake knife. I am also not responsible for any damage that is caused during and after the process of creating this knife. Also while this knife is safer than a real knife, it may still be able to cause harm depending on the way you have created your knife.

Now that we have that seriousness out of the way, continue onto the first step where we will learn what is needed in order to create our own prop knives!

Step 1: What You Will Need

I purposely created this instructable in a way that is 1. easy for someone to understand, 2. uses household objects, and 3. is low on materials. The materials used may vary depending on what kind of knife you have. This may not make sense now  but it will later on in the instructable. Here is what I used and what you will probably use:

-CD (These can be bought very cheaply at stores if for some reason you don't have one)
-Lock Blade Pocket Knife (Not huge wooden BUCK knives but the metal/plastic ones like what  Gerber makes)(Your knife will not get damaged in any way)
-Sandpaper (I used a fine sandpaper but any kind works)
-Razor or EXACT O knife
-Fine tipped sharpie or pen
-Different sized screwdrivers (Either Philips or Standard depending on your knife)
-Allen Wrench or other tools that fit the screws on your knife
-Paint (Preferably gray or black spray paint)
-Various Drill bits
-Compound clippers (This is one of the items that you may not have and can be easily substituted)

Right now it may seem like this will be a hard thing to do but really you only use each of these things for a minute or two. Lets continue onto step 2 so that I can explain what is going to happen and how to prepare your pocket knife.

Nice write up. My only concern is how 'safe' this really is. This knife may break easily at the bolster (since it's the thinnest), but I bet in a thrusting motion it would easily stab someone. I agree that it's safer than metal, but can still be very dangerous. Think of any prison documentary you've seen, it doesn't take much to make an effective weapon. Do what the pros do - film a real knife in close shots, and switch to a safer knife in action scenes. It does look pretty convincing though.
<p>Totally agree with you</p>
Good instructable, but shouldn't a prop knife be like not harmful and be able to look like it stabbed a person without stabbing them?
It is actually all in the camera shots. Unfortunately there is really no prop knife you can create that makes it look as if you have stabbed something. You can however create a latex wound where the person gets stabbed. You can also cut the knife in half and when you switch camera shots have the half knife inserted into the latex wound. You can really just experiment with different ways of making it look realistic. But thank you for your feedback and hope to publish more &quot;prop&quot; instructables soon! (I am working on a few grenade props at the moment)
hey, couldnt you like make it a plastic spring loaded one? like it gets pushed into the handle when you &quot;stab&quot; them?
Ya, I'm sure that if you get a cheap switchblade from a flea market or something but take out the locking mechanism then that would work as well.
yeah, and it would be possible (though difficult) to make it deposit some fake blood when it stabs
Woa that is cool. Where can you get that Gerber thing you talked about?
Gerber is a knife/multitool company, <br>you can get gerber multitools in camping shops and you can get their knives of the internet (i.e. amazone, ebay)
hey do you want to see a reel prop knife go to /www.instructables.com/id/gun-setprops/ and please leave a comment
That is so AWESOME!!!!!!! Thanks so much! I've needed a way to film with knives!
Or you could use a transparent CD protector ( It's the one on the top of a box of writable cd's) ;)
pretty cool instructable good job very nice cutting i will be making one of these!
nice instructable!
