Step 12: You Have a Knife!

It's ready for finish sharpening as demonstrated here.
Here's how to make a paper sheath so you can carry it safely in your pocket.

That was quick!
It took less than an hour according to my photo EXIF timestamps in spite of interruptions such as rain and repeatedly hitting my camera with a hammer (canon s30 "E18 error").

Use your knife safely!
As my Granddad used to say, "Don't cut toward yourself and you'll never get cut!"
How long does it takes to sharpen? Cause mine doesn't get heat up
<p>i make small knives so be shure to look at these pics. </p>
<p>this is great! if you heat it in a forge first then temper it again(becuase it will loose its temper in the forge) then Quench it sevral times, you can get a super strong knife it just takes tme. if you wrap the handel in wax string, you get a sweet grip and its hold a edge werry well.</p>
nice i use it like a throwing knife
<p>I made it and I enjoy it.</p>
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.
<p>just use a wetstone!</p>
awesome instructible! works great, made a couple variations too. thank you
Your my hero!
hunting knife, prison shank, potato, pottoe
ok I like the idea but there is no freakin way a sharpened butter knife would serve as a reliable knife
This looks easy and fun
Lol can't wait to try it!
I made one and it is awesome I also made a duck tape sheath with belt loop it was easy. Thanks
Nice instructable another step you can add is heat treating it in an oven, it will make the steel much harder
OOps, Guess i shoulda looked ahead!

Very nice! looks like a good project. <br> :D
'HOW TO BUILD A KNIFE WITHOUT TOOLS&quot;<br><br>STEP 1. Get a Drill Press.<br><br><br>WTF........I feel lied to.
Lol, right
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.
A rock would be a tool in that case.
&quot;Cement is a good abrasive. It goes pretty quick&quot; <br> <br>Ha ha, good one, you're funny.
I love this just made one I wrapped my handle with tape.
my version of this cool knife:
if u dont want to drill hole and raeally make it without tools just get electrical tape it really gives it a leather bound look
this is really an awesome idea. now i just have to go and buy a set of butter knives so i dont get my ass kicked for using my parentts butter knives ;) but i sttill made one though. then my mom took it when i showed it to her -.-
Knife, shank.... potayto, potahto...
honestly...the curve of the butter knife blade &quot;edge&quot; 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.
what if it isnt a hunting knife ?
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
Tanto Blade
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&quot; nylon boot laces work wonderfully. You can by a pair of 72&quot; 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.
He meant wal-mart
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
&nbsp;anything spinning at drill speed is sharp enough to do serious damage I think...&nbsp;
Even a dull knife can cut you. And spinning at 630 rpm will only multiply the hazard. <br />
i made one of these last night and also a simple sheath thx fr da onstructable its a goood one
using a 'whip knot' would make a better handle. it's used to finnish the end of a natural fiber rope that can't be burt n sealed. it's similar to what's been shown. u make a loop with a tail along the blade, wrap the handle, stick the end in the loop at the pommel then pull on the tail along the blade. loolk it up in the 'knot' section, i'm sure it's there
Why would that be better? This looks like it might be more secure to me.
You don't have to drill any holes in the handle, which weaken the knife, to secure the wrap. Also, tied properly it won';t slip off at a bad time. Hemp ropes that are whipped with about 1&quot; of whipping don't fray for years n years.
Alright, but hemp is a whole lot rougher than metal, and parachute cord, if that's used...or really most cord, especially synthetics--is less secure than the waxed string I've seen used to whip rope. If we're using a butter knife, are we really too concerned about strength? An eighth-inch hole isn't much. What do you use to whip your rope?
