Picture of Knife Making Without Tools
Here's how to make a hunting knife from a butter knife by rubbing it on wet pavement and wrapping the handle with cord. It looks and feels good in the hand.

This project was inspired by a family I stayed with in Kenya. The only utensil they had was a sharpened butterknife shared by about twenty people.

Select your "blank":
Test your butterknives by bending the blade with your fingers. The farther you can bend it without it staying bent, the better it is.
Instead of a butter knife, you could use a saw blade or any piece of metal.

WARNING: I will be showing a bunch of OPTIONAL steps using tools.
For purist "no-tool" knifemaking, just skip all the steps using tools.
Or just substitute "with a rock" for the name of the tool.
Your knife will be fine.

Step 1: Optional: Drill Holes in Each End of the Handle

These are to tuck the ends of wrapping cord through.
Skip this and the wrapping is the same and 95% as good.

Step 2: Optional: Countersink and Smooth the Holes

I'm using a countersink and some sandpaper to do that.
This will keep the burr on the edge of the hole from biting the cord or your hand.

Step 3: Optional: Melt and Taper the Cord End

This will make it easier to poke through the hole. Unnecessary if you skipped the holes.
Get your fingers wet so the melted plastic won't stick and burn you like napalm.

This is 1/8" nylon "parachute" cord. 1/8" Polyester is better because it doesn't get loose when wet. Get it at a chandler. (marine supply)

Step 4: Start Wrapping

If your cord is nylon get it wet first.
If it's cotton or other cellulose fiber, make sure it's dry first.
Nylon shrinks when it dries, cotton shrinks when it's wet.

You don't really need the hole, that's just something to make it look less like a butter knife.
If you drilled holes poke the cord through one of the holes.
Leave a tail a few inches long.
If you skipped the hole just lay down the tail and wrap over it.
Wrap over the tail until you get halfway up the handle.

use nylon #550 cord. put it in boiling water for about 25-30 seconds. it will shrink and tighten if you wrapped to tight to start.

just use a wetstone!

awesome instructible! works great, made a couple variations too. thank you

Nice instructable another step you can add is heat treating it in an oven, it will make the steel much harder

'HOW TO BUILD A KNIFE WITHOUT TOOLS"

STEP 1. Get a Drill Press.


WTF........I feel lied to.
Lol, right
ValScott viacin2 years ago
Umm... optional, I think, was the key word in the intro that you possibly ought to have read. Yeah.
If you are going to advertise the knife making process as being without tools, then you should actually go through the process of making the knife without tools. Saying to skip all of your steps and to use a rock instead of the tools that you are using is lying. Anyone can rub a knife on a rock.
tincanz Gcamper2 years ago
A rock would be a tool in that case.

honestly...the curve of the butter knife blade "edge" is already ideal for a hunting knife. try skinning anything out with the style of blade you have at the top and you'll end up with a bunch of slices in the hide. all id do is remove material on the back until you have a drop point style blade and thts it for shaping it.
sheet metal makes a disposable, yet sharp knife. all ya need to do is but a 40ish degree bent on the back bone to make it flex less

Yeah that was kind of an out of place reference. However I do applaud the effort, good show I say.
To sharpen it you could use the bottom, unglazed, ring on a mug

I made the blade on a butter knife and I didnt have to cut away anything. It just took a little longer to where away the metal into a point. I just have a few questions about the handle. Where could you get parchute cord? Would there be any at a walmart or sporting goods store? Does any one have any other ways to make a handle?

For this particular purpose, 1/8th" nylon boot laces work wonderfully. You can by a pair of 72" laces for a coupla bucks at wallyworld giving you 12' of working material. If you deconstuct one you'll find a braided cover around a central core, same as paracord. The difference is essential contruction. True paracord has several cohesive strands forming the core; the bootlace core is more like a clusterf**k, but after deconstruction the separate pices of both can be used for string, thread, etc. enabling you to repair jeans or create fish line for instance.

Well the knife's not sharp yet, so theres no real risk.
A dull knife is often more dangerous than a sharp knife because it is likely to slip when cutting something, thereby giving you a lovely slice and a serious need for stiches.
ya lets play the super glue game
its still sharp enough to do some serious damage, safety precautions shall always be followed
