How To Make a Fighting Dagger Out of an Old Steel File 

+Luke Loder I thought he had a GREAT camera Presence! He is confident, doesn't say Um or Ah and he knows what he wants to say. I like watching his videos because they are not cringe worthy and not distracting from the actual topic of the video.

+ssunfish thats what i noticed! That can distract me so easily. This dudes straight to the point with no funny business. Must have a pretty cool dad/mom(:

+blabada 123 ill bet you haven't been laid either at all or in a long time

Luke Loder im 13. What do u think.

+blabada 123 we're done here LOL i wont argue with someone online, especially someone who hasn't finished secondary schooling quite yet.. Id just feel like the cancer myself. have a good one fam

Thank you!

+BackyardBowyer Excellent video, liked, and subscribed.

BackyardBowyer Subscribed. Great video... With minimal equipment...Genius to the max..

Willie Pierce untuk

And very easy to understand the steps when your making it :-) Thanks great video :-)

l

jaye see fuck u

Hmm

LOL You ain't right!!!

Keep choking your snag jaye see

Haha! Thanks!

Brainake check out his other videos, he's a blacksmith :-)

same,... guy really knows his shit

+Cosmas B Could not agree more!

+Cosmas B Right

Pretty cool for low cost low tool tech

well said

+tetsubo57 yes.

Its worth the years off work tho

So true! 👍 What it also doesn't show is all the new guys filling their trash cans with snapped, melted, fractured and oddly shaped files bought from the discount store whilst trying to copy this video on a Saturday afternoon. 😂😂

+tetsubo57 so true, He makes it look easy.

+Anomaly ANOMALEH omfg :D

ha, the fuck you doing here?

+Andy ednios hahahaha thought the same

+Anomaly lol anomaly?

+Anomaly yeah lol wtf u doing here

Hard work and dedication shits on talent every day lol.

Daniel Cruz you can

most people have jobs that suck the life out of them until they are nothing but a brain dead husk at the end of the day only fit to keep a chair warm begging god to make it hurt less until the weekend comes, never making enough to buy the tools necessary to get this kind of skill.

You can, he just showed you how

Half Insane Outdoor Guy this is extremely basic stuff that doesn’t require any special tools, anyone with two functioning hands could do it, they could even make it easier by going on amazon and buying knife blanks for a few bucks. Realistically you could do this with only one functioning hand and a table vice, so long as you can get a good grip on your grinder, or you spring for a $70 belt sander and a lot of belts and pads from harbor freight or Home Depot.

You also need some sort of forge ,a quench tank of oil and a bucket of perlite. Unless it's just for display,then your tool list would work fine.

+Ernest Sheffield Like no fucking kidding... I was looking at him do the bevels with a god damned angle grinder and I was like , well I need to watch a different video because there is now way I can do that... lol

+JD Tremblay sure you can... just get it close then draw file it to final shape... hell, I've made a few knives where I only used files... can be done, just takes longer.

tritowns I just made a kick ass knife today man; made a forge bought some bloodwood and purple heart, made some mosaic pins out of brass pipe and steel rods just need to shape the handle tomorrow and make it all shiny shiny!

tritowns I used an angle grinder to do exactly that, got it down to pretty close then finished it off with a bastard file then heat treated and so on :D as you can tell I am stoked and proud lol

+JD Tremblay That is no way to talk about your files dude!Show some respect for your tools! 😉

yes he did i couldn't agree more its a beautiful dagger

Hold on, your grandad didn't happen to migrate from Germany.. did he?

James Gordon this dagger is by the looks of it based on the fairbyrne skyes fighting dagger used by british commandos (SAS) during World War II and to this day its on their unit flash on their beret

Yeah, kind of a more German look to it.

@@beerthug ibuyworldwar2.com/tag/ss-daggers/ LOL

Especially when you realize it is a Harbor Freight grinder. lol

joe rohling equipment second to skill

Days of practice

Aj Ginther I am waiting you do a video better than this one, good luck

Years, I would say. xx

9

really?

Wiz V no he's just messing with you

Cristos Palabras us Indians where in the crystal age before contact (obsidian age higher than the so called Clovis culture of europe.) so yeah that knife blade was shaaarp!!

Either You're blowing smoke up everyone's ass or you've never worked with your hands and have soft baby hands

Thanks for watching! It's a Schutzstaffel dagger with an ebonized wood handle with the SS runes inset.

+Chase Ramos the fire brick or prolite?

shuv it up your ass

Kendall Reinhardt lol what

+thepuppetmagician Tempering is a part of heat treating. There are many things that can be done during heat treating and different steels require their own heat treatment to perform their best. Most steel manufacturers give heat treating instructions for the steels they produce. Basically when you heat treat a knife like this, there are three basic steps. The first thing I did was anneal the file, which brought it down to what is known as dead soft. This is where the crystal structure of the steel is very fine and under little stress. This can be done during heat treatment to relax the steel and ensure the crystals are all uniform in size and type. You can also normalize, which means bringing up to critical and then allowing to air cool, a few times. Next, I hardened the file by bringing it up to critical and then quenching in oil. Different quenchants cool steel at different rates, so you need to figure out what works best for the steel you are using. Oil is generally a slower quench and can help keep the steel from getting so stressed it cracks or breaks. Water is faster and various brines are usually the fastest. There a lots of ways to harden a knife, and sometimes only part of the knife is hardened. Finally the knife needs to be tempered. Tempering is basically heating the hard but brittle steel up to a certain temperature (in this case 400 degrees F) to remove some of the brittleness and introduce some springiness into the knife. There are ways to heat treat without tempering, but generally knives like that don't have the same springy quality as a knife that has been hardened fully and then tempered back. They tend to stay bent when bent rather than spring back. This is a really basic way to talk about heat treating. Heat treating steel can be very complex, but hopefully this helps!

+thepuppetmagician heating the steel up to critical and then quenching makes the steel very hard but also very brittle, tempering sacrifices some of the blades hardness but makes it much less brittle and less likely to snap or shatter.

+thepuppetmagician When you're dealing with a hammer-forged metal, especially if you are twisting or folding the metal, certain stresses can build up within the metal due to it being stretched out in some places and compressed in others. Rapidly cooling the metal in water or oil causes it to become extremely hard, so it's essential for blades, but thermal shock is an issue - imagine dipping a hot wine glass into cold water. It will shatter. If you don't alleviate the built-up stresses in the metal before hardening, the same thing will happen to your piece. To do this, you heat the metal to just past the point where it loses magnetism, and allow it to slowly cool in the air, and repeat several times. This evens out all the stresses in the metal and reduces the risk of the blade breaking or warping during quenching. While you are working on the shape, you need the metal to be soft and malleable, but it can't hold an edge in this state - so quenching is necessary. After quenching, the blade is extremely hard, but also extremely brittle - it would shatter if dropped. So it must be made a little softer and more flexible to be able to absorb impacts better. That's why he put it in the oven for a while. This softens the blade slightly, but not to the point where it can't hold an edge. The hotter you go, the softer the metal gets.

+thepuppetmagician The best way to think of it is that heating and quenching tempers the steel. Baking the steel then relieves the stress caused by tempering, which is what makes the steel overly hard and brittle. This part of the process is called "stress relieving".

when you don't heat treat metal and try to bend it, it will bend and stay that way. when you heat treat, during the first step you make the blade super strong but its very fragile like glass, you quench it in oil so that it doesn't have time to just cool down and the atoms to go back to their normal state. on the second stage when you heat it to the wheat color, it relaxes the metal and makes it more resilient. If you're still interested and have ever looked and studied a katana you'll notice it has a slight curve, this is due to the fact that when they heat treat it, in the first step they but clay over the spine so that it stays strong and won't get a dent when it gets hit, but because of this when its quenched the spine contracts and the blade expands creating the curve... sorry if I didn't explain things very well or if my grammar was bad don't judge, I'm only 13

+Fletchett Thank you!

I think its easier but grinding is more fun

+wayne maciasac Hardly.

And hot file.

+Rex Mundi Your profile pic makes that statement perfect.

Awesome! I'm glad this video helped.

+BackyardBowyer Could you make one for me just like that and I could pay for it?

I annealed the file by heating it to cherry red, then slow cooled it in a bucket of perlite over night. Made it very easy to work.

Josh Dukowitz whrn tjer they not shebe there was not hood

I say so

They shebe ur neck and sted

It all

I did my oun thanks

Thanks for watching!

XD How did you think of that while you were watching this?

"That hurt"

Likeitornot I have no clue

+tito1rocks hahahahah!

Tomas Tamosauskas It's called pearlite, it's a medium used when growing hydroponics. You might be able to find it at garden centres?

Thank you.
