I'm not here to dissuade you (rather, I'd like to encourage you), but let me first get this out of the way: knife making is a slow, delicate, painstaking, multi-faceted, sometimes frustrating process. It requires skill in metalworking, woodworking and design, patience, attention, and general levelheadedness. You have to take your time if you want to do things right, otherwise your experience will be sub-optimal. Even I have trouble with this sometimes, as this project will, itself, show you, and some of my past projects will blatantly scream...*wink.* Don't be frustrated if your first project doesn't come out the way you want it. All good things take practice, and you may make several knives--or several dozen--before you make one you really, truly have no beefs about. But it's good fun, too. You can do it. Don't worry.
Okay, so you still want to make a knife. Read on.

Signing UpStep 1: First thing's first...design the blade!
First, plot out the blade and handle shape on graph paper. Try to get it as close to actual-size as you can. The less changing you have to do to the design once it's on the steel, the better.
Now you need to decide how to attach the handle to the blade. There are three common methods of doing this: a full tang, a partial tang, or a through-tang. A full tang has the same profile as the handle of the knife, and the meat of the handle is formed by two slabs of wood (scales) to either side of the tang; most good knives are made this way. The knife I'm making here is a full tang knife. A partial tang is the most inconspicuous of the three and, in my view, the hardest to make. In this design the tang is a rod that protrudes back from the blade and is completely hidden inside the handle, secured with a rivet or two. Japanese swords and sushi knives are made this way, though the latter is secured with a cuff rather than rivets. A through-tang knife is similar to the partial tang except that the tang extends all the way through the handle to be secured by a nut or by peening on the other end. Ka-bars and most turned-handled knives are made this way. Choose whatever best suits your project. There is plenty of info on the web if you're not going to make a full-tang knife, though I recommend it for a first project.





























great instructible by the way!
I am a blade smith so I don't do the same processes as you do with your stock removal methods, so I was wondering if you wanted to try black smithing. It's allot more freeing than stock removal and you can even get most of the bevels on your blade before grinding. I am trying to make very cheep forge setups for people and if you would like, I will share my knowledge.

PS. I could have put a more defined half edge on it but, sort of like it the way it came out. it tapers a lot more than it appears. And yes that is a duct tape sheath, only took me 20 minutes to make, complete with a belt loop and a strap to hold the knife. Plus keeps the blade dry. and was FREE. actually I didn't spend a dime on this whole project which was nice.
Freakin autocorrect
I love this tutorial its exactly what I was looking for.
I've also used a lot of 5160 and it's a joy to work with. That's your basic leafspring steel, but you can buy it in bars as well. All of this is oil quench, and make sure you use this kind of steel for your first knife. Things can go wrong faster with a water or air quench.
If still in doubt, you can always try scrap steel. I think I mention in the guide (it's been a long time now, forgive me) that you can use most files or saw blades to make knives. I've picked up lots of dull files made of good steel at flea markets, and turned them around into nice knives. Avoid cheap files--and I mean dirt cheap--because these can sometimes be case-hardened mild steel.
thanks Basta
just heat it up reall hot, cherry red? then bury it in sand or ash, or some insulator, then let it cool. this will make the metal soft.

Also, try googling Admiral steel, And Aldo (known as NJ Steel Baron). You can also buy a lot of different kinds from Jantz knifemaking. Expect to pay for your shipping though. If you have a friend that runs a business, see if you can get it shipped there. I got my order of 11 LBs of steel to go from $30 something for shipping, to $13 something. Just by having it shipped to a business instead of my house.
shipping is killer, though.
i like 1095 steel, because quencent for that is normal water, instead of complicated salted vegetable waste oil whatnot
plus, water doesn't burst into flames when you stick a 1095 into it
and ka-bars ar made of 1095
The chopping tool you made also works great on defatting/thiinig deer hides prior to tanning.Nice job!
And Basta....What can I say,Beautiful job!
LokiGnosis,that knife needs to be in a glass case in a showroom.Stunning!

Is takin ages
Just a thought.

I agree, a knapped steel knife would be kind of awesome! The problem is that steel has a very different internal structure than glass--while glass is very uniform and will break along a very predictable line of stress, steel (especially hardened steel) has a really coarse grain structure that breaks more like gravel-filled concrete than glass.
Maybe if we have a metallurgist here we can figure out some way to make it work, though....
The handle looked crap and was really thin so i attached loads of rubber bands and string to it and put on a serrated edge. I also made a sheath out of metal pipe but it also looked horrible and had loads of sharp edges so I coved it in duct tape.
It is so sharp that I acidently sliced my thumb open to the bone and didnt realise until the next day when i had blood all over my bed and my thumb was hanging off.
I got it so sharp by using my method on my instructible on how to sharpen a knife with a nail file!!!
Maybe it's time for an improved instructable...
cool
please look at my 2 as-well.
ps one might not yet be on as I have only just published it,
how to nap flint cos i dont know how to
A2 is an air-hardening steel--how did you alter the hardening procedure?
I made a knife recently using some tips from your instructable. I have a fair bit of metalwork experience (mainly turning, milling etc) so I tried my hand at a knife. The result is below. By the way I recommend you get some thin cutting disks for your angle grinder. They cut through hardened steel like butter and you'll never go back to a hacksaw when you've used them.
My knife still needs buffing and a wrist cord but it looks alright already. I might do an instructable on it soon.
Thanks
Since I made the instructable I have started using cutting disks--they're great, except that they wear out every five minutes! I always seem to run out halfway through every other project. Maybe I should start buying in bulk.

cuz if that's the movie, then why does it have saw teeth? i don't remember those
ill post some pics soon as i just joined.
also i am 14 but i was being safe :D the quenching was awesome but i love the final product. its going to be a hunting knife.
thanks for reading all that

Excellent, keep at it because who knows how good you can become if you are already doing work like this at 14 .
I could barely make a cup of tea at 14.........................
A more frightening thing is that I have been out even later, Shock, Horror!
Here's a pic outside the "Ain't nothing but" bar in Londons Soho, at 4:30am and a 2 hr drive home, I know, terrible isn't it............
Blues, Booze and a Blonde (The Wife).
Anyway, enough banter, as I said before a really nice knife........well done.
Loki.
Bravo! And good luck with all your projects.
I can do metric if you need it, too.
A typical katana has a handle that extends about a quarter of its length past the end of the tang. How is that really considered to be full tang?
I'm not trying to be jerk, I really don't know :)
and regardless of what ever the previous comments- the above is still a pretty good knife.
Thanks; I believe it's a good knife.
http://knifethrowing.info/make_your_own_throwing_knife.html#pahl
perfectly balanced
i had the same problem. stupid new york laws make throwing knives hard to ship and get.
it's a heavy brake drum, but for light use an old hub works.
You need real blacksmith coal, too, not anthracite. Look for it, it still exists.
Another way is to place it in a bucket of ash this insulates the blade and makes the it cool more slowly which gives you a better anneal.
Note: When using this method you should first heat a piece of scrap steel and place it in the ashes first to preheat them.
Those are my tips for drilling hardwoods after about 8 years of woodworking experience.
Not sure if you wanted to know all that, but in case you did...

and thank you for your comment
a) use a brick tipe (weber) bbq with a fan of some sort ading oxigen EG vacume cleener hair dryer etc

Also, in the picture it appears that y dont youre using some kind of diamond cutting, or incredibly fine rounded blade, is that so? or is it just as you said above, a bi-metal blade?
thanks so much. this is a great instructable, Im a bit sad I didnt find this before I became wholly invested in forging knives, as this seems a bit quicker (even if you get to pound steel! =) )
True. You would fold it nine times. Each time would double it, so it would go 2, 4, 8, 16, 32, 64, 128, 256, 512.
If you want, go to my instructable about how to build a hidden tang knife.
For design inspiration: Jay Fisher's knife designs. If you can't find something you like, invent something.
www.onlinemetals.com is a good site and www.mcmaster.com is another good one...
both i have used to get materials like sheet metal, or sheet plastic and they're pretty good... you usually have to get stuff like this online...
he had a "bowie" style knife, if you want like a crazy awesome ninja kind of knife, then it's a "tanto" blade... Read this wikipedia page, and look through the different knives, i guess....
however, the polishing wheel is The most dangerous tool you will use in making a knife
Even if you sand the with the blade edge 'trailing' in the other direction from the rotation of the wheel, it can still grab it and fling it across your workshop, or, if you are unlucky, into you.
http://tidewaterblacksmiths.net/5.html
look at the one about the wire wheel (they behave in almost the same way)
ouch
He probably has the biggest stockpile of knife designs I've ever seen in one place, something for every taste.
And as soon as I make anything else, I'll post something about it. Do I have any support for a butterfly knife-making instructable? That's my next project.
get a mtech folder model CEMT30 loosen the screw
If you look at the rest of the comments you'll see some of my recommendations; try industrial supply outlets, look in the phonebook...or try used sources, like old files or saw blades.
http://www.instructables.com/id/How-to-Build-a-Sheath/
they have a couple things that look right but im not sure under carbon steel plate they have A36 steel but in another category they have tool steel like 0-1 which do i get
He's got some good info here, especially if you want to make longer blades.
Grinding and polishing a blood groove is difficult, and I wouldn't recommend it for a first project. Many medieval swords had blades with a diamond-shaped profile. You'd probably want to forge a groove, and then sand and polish it by hand or with a dremel. A lot of it is trial, error, and common sense.
Have you experimented with.. I don't know what the proper name is, but tempering the blade of the knife to be harder than the spine? The way it's done on katanas that produces the wavy pattern, by half-covering it with clay and then quenching...
I'm also a fan of carbon steel- during years of getting through many stainless knives, I had an old Sabatier made of proper carbon steel (the blackish stuff that you could smell the acetylene coming off when it was wet) that never needed sharpening in about 10 years .
Society of Automotive Engineers (SAE) have a four digit code. The first two numbers are the basic alloy content of the steel. The second two digits are the carbon content of the steel. I.E. - 1095 is a plain carbon steel no alloys and has 0.95% carbon in the steel. 5160 - low chrome (51) high carbon (0.60%). In the stock removal method (non forging) that is being used here I would start out using O1, 1070-95, 5160, or W1. Common steels found are old files - usually W series. Truck leaf spring - 5160, 1095. Sawmill bandsaw blades - L6. These are just examples of where to find steels. I personally would buy a bar to start just so you know exactly what the steel is. Good source for steel and knife making supplies - http://www.texasknife.com/vcom/index.php
I hope this helps, personally I work in L6 and 5160 alot but I use a gas and coal forges and forge my knives and swords. So starting out stay away from the high alloys and stick to the 1095 and O1 as these are some of the most forgiving of the tool steels.
Can I ask though, you don't seem to be a fan of high grade SS. Is there any reason to that or are you letting beginners know that mild steel would be a good start.
What do you use to seal your blade? As I would assume it may begin to tarnish.
In case your interested, I recently began making some blades myself. This is my first. (stainless), I had this one professionally heat treated. As you would know, not a practical task at ones home. I only have a small forge running on mapp gas.
The best purchase I have ever made was a dremel. The cut-off wheel easily cuts most grades of stainless. Polishing pads arn't bad either.
Good work!! 1+
