It doesn't happen often, but sometimes I like to offer some well-tempered advice to fellow blade makers who could use some guidance. Here is a selection of wisdom I've previously shared to help keep others on the right path in their blade-making adventures.
 


That ain't how it works.

I know you want to design knives for e-commerce, but there's a lot of balderdash, blatherskite, and boloney out there about making the damn things, so I'm gonna help you out and tell you how it's done:

First thing, you head on out on a clear sky day and you look at the sun exactly 2 hours before sunset. Just have a good long stare at it. That's the color you want for quenching. Not an hour before, not an hour after.

Next, you gotta pick the right steel, and that's a lawnmower blade. Not just any lawnmower blade, is has to be a John Deere mower blade or it ain't gonna work right. That blade better be used, too, so it's been good and jiggled. You gotta make the far end of the mower blade the tip of your knife, because most of the carbon gets spun out there when the blade's jigglin'.

Now once you got that blade heated up to the color you seen in the sun, you gotta quench it, and nothin' better for quenchin' than a cold, flowing creek. It's gotta be flowing. Just toss it on out there, and fish it back with a magnet on a string.

You get that right 500 times in a row and then maybe, maybe, you'll be ready to make a knife for e-commerce worth a damn.

Ain't no knife never been made worth a darn what ain't been caressed by coal and kissed by a hammer! :mad: "Carbon, iron, and heat, what makes a knife real sweet." Now you tell me what in tarnation's a man to do with a knife what ain't been forged by muscle and sweat? This ain't Sally's gumdrop and lollipop factory. Now go on and get to rustlin' up some spikes! Go on now, GIT!
 


All right, here's what I'd do iff'n I was you.

Get ahold of an old pedal grinder. They look something like this:

You're in Oregon, so those things are all over the place.

The large wheel turns slowly but can shape steel pretty quickly and safely. You can shape all kinds of knives on that, quietly and without even needing electricity. None of this sissy 2x72 malarkey.

Now the hogs ain't gonna slop themselves, and the tractor needs fresh blinker fluid, so go on now, GIT!
 


I reckon that means it's harder to break it by bending it over, than it is by pulling it apart, then now ain't it! :oops:
 



That ain't how it works. If you want to heat treat a blade, there's only one way to do it right: differential hardening and an auto temper.

What you do is jack up the back of your pickup and take off a tire, so now you have a steel wheel up in the air. Now you fire it up, throw it into gear, and put a brick on the gas pedal. Make sure to put the brick on the pedal after you put it into gear.

Now you squat down there by the steel wheel which should be spinning nice and good, and you start rubbing the knife blade on the wheel until it starts glowing red. As soon as it's glowing red halfway up from the blade edge, you stick it into a watermelon for exactly 8 seconds, then pull it out and stick it in the exhaust pipe for a bit for an auto tempering.

Now you got the best knife knife you can get.

This is why it's called differential hardening and auto tempering.
 




That ain't how it works.

Every time some fresh meat ends up in knifemaker jail, the whole cell block starts feedin' 'em a bunch of nonsense just tryin' to dupe 'em out of their e-commissary. Now listen here, and I'll tell ya how it works.

First thing is you need Japanese steel. Bar none the best place to get it is from a Takeuchi backhoe, which has everything you need to make a knife for e-commerce that's worth a darn.

You can find them around, usually where someone's fixing up a road. Check on the weekends and you can usually find one just sittin' there. They look like this:

Now once you find one - and make sure it's a Japanese backhoe, because the steel in them yellow ones ain't worth a darn - you gotta get inside the booth and fire it up. The drivin' booth looks like this:

Stick a flathead in the key slot and twist it until it wakes up. Then drive it back to your knife shop.

Now once you got the hoe, you want to get the right steel from it.

First you pull out one of them big pins on the digger. This is your anvil.

Then you grab one of the benders on the arm. It's the best hammer you'll ever swing.

Now go to the bucket and unbolt all them little teeth. That's your knife steel, and that's the key: those steel tooth nuggets are made for diggin' rock, now you tell me, what better knife can there be than one made for diggin' through ROCK? That's right, you can't 'cause there AIN'T.

Next you open up the hatch on the back and pull out the water tank. This is your quench tank, and it's already full of green quenchant ready to go.

Now you got an anvil, you got a hammer, you got your quench tank, and you got your steel knife nuggets. You already said you got tongs so we won't worry about that. Next you're gonna want to heat n' beat.

Grab a hose and siphon out a good bit of diesel, pour it in the bucket, and light it up. Don't worry about the black smoke, that's good for the steel. Us pros call it a carbonizing flame because it bakes more carbon in the digger teeth, which is what you want: carbon. Grows hair on your chest, too.

Use the diesel fire to start heatin' and beatin' until all the teeth look like a knife. Beat 'em all the way into a knife shape, so you ain't gotta do none of this sissy big city grinding, and if you do, it better be on a stone wheel.

Now heat up the knives until they're orange and dunk 'em in the quench tank. Scrape 'em on the backhoe treads to see if they scratch. If they scratch you gotta heat 'em up hotter and try again.

Hold your horses, they ain't done yet.

Last thing you gotta do is drop the knives in the smoke pipe of the backhoe and fire it up. Put a brick on the gas pedal and let her run full speed until the engine stops running. That's when you know they're done cookin'. We call this tempering because it calms down the knives. Now flip the backhoe upside-down and dump out the knives.

There ya go, you got yourself the best dang knives you'll ever see, made of Japanese steel and ready to cut right through rock if need be. Don't let anyone tell ya otherwise.

Best thing is, once they all get e-commerced you just head out and get another backhoe for the next round.

That ain't how it works.

Now, a lot of folks out here on the Net are wantin' to make knives for e-commerce, and they're gonna get a lot of bad advice from every which-a-way. I'm here to give you the real McCoy.

Some yahoo is likely to come in here with some nonsense about forging rail spikes all damn day until they look like a knife.

Wrong.

This is a common misconception that came from the RIGHT way to make a good knife, which isn't rail spikes, it's TRAINS.

What you do is head to the rail yard and take a look at the train cars, until you find one with flat springs. They look like this:

It's those stacks of flat metal, perfect for making knives. Just bring some tools and take as many as you need, there's rail cars all over the place in the rail yard. If anyone gets to jaw jointin' at you about it just pay 'em no mind.

Next you take the flat pieces and lay one out on the rail track in front of a locomotive engine car. Now all you gotta do is heat up the flat spring bar with a propane grass burner until it glows good n' yellow, and have the train driver roll over it until it's thin. Ain't no hammer that's as strong as a train.

Now take the bar and heat it up until it glows again and dunk it in a barrel of train fuel.

Use wood from the rail ties for a handle, give it an edge and there you go. Do it enough and you have yourself an e-business making train knives. Any other method is just a waste of time and a scam to get you to buy fancy tools you ain't need.
 


Checkmate.

Looks like it's back to the CAD program drawing board, Liberty_Knives. o_O

Now, if you really want to make knives, I'll tell you what the pros told me: you go to the rail yard and pick up 1,002 railroad spikes, 500 lbs of coal, a piece of railroad mainline as an anvil, and a 5 lb engineer's hammer. Then you forge two of the spikes into a pair of tongs. Take the last 1,000 spikes and start forging them into knives, one by one. After the last spike has been forged, then, then, MAYBE you'll be ready to make a knife. o_O
 





Look, I know you think you want to make knives for ecommerce. Lots of upstarts think the same, but they never get any good advice, so I'll help you out.

First, you go get yourself 500 railroad spikes, a coal farrier's forge, and a 3 lb ball peen hammer, a good pair of vice grips, 500 lbs of coal, and a piece of railroad mainline.

You take those railroad spikes and you start forging them into knifes, one by one. Forge them completely to the final knife shape, none of this sissy grinder nonsense. Keep forging until every spike is a knife.

Then you take the knife billets and you start heating them up until they glow enough to where a magnet doesn't stick to them anymore, and dunk it in the creek. Do this for all 500 of them.

Then, maybe, just maybe, you'll be ready to make a knife worth a darn.
 


Bar of knife steel? I got one word for you: railroad spike.

The way it works is when you fire up the coal it puts more carbon in the spike, and makes the carbon high. Make it hot enough to sparkle. The sparkles is the carbon going into the rail spike.

Once you figure that out it's time to get a pre-spun mower blade. Make sure it has at least 500 hours on it mowing so it's good and spun. John Deere. Fold it like a taco over the pre-carbonized spike, and be sure to leave on the black paint, it's just like built-in flux. Heat it up until it glows and beat it over a rail tie with a railman's engineering hammer. Hit it hard.

Beat it into a knife blade and heat it up again, then throw it in the creek. Use a magnet to fish it out, and scrape it with a horse file. If it skids then you did good. Do this 500 times and then maybe, maybe, you'll be ready to make a knife worth a darn!
