does this method really works?

Leaf springs are typically something like 5160 or 9260. Easy to forge and HT. Why the complicated HT I don't know.It needs only a simple Q&T.Many jungle knives use these steels and HT.
BTW a parang IIRC is the name for the jungle knife of Malaysia and Machete is the name used in Central and South America.
 
It really depends on your definition of "work".

Judging by the quality of the finished product and the silly music, I'm inclined to believe the guy really doesn't have much experience with making knives. His description of the heat treat process was really nuts, in my estimation.

A brine quench is entirely proper if you have the right kind of steel. It's a very fast quenching and entirely inappropriate to a whole host of alloys. Then his "tempering" set up had zero control over the temperature and didn't evenly impact the entire blade. By setting it on the metal rim like he did, he's effectively creating a line of demarkation that prevents the heat from traveling farther. Because the tip is so far removed from the heat source, I doubt it tempered properly.

Will the contraption last? Probably. You have to remember that it's not a working tool that will be used for hours a day, month after month, like you might see a Brazilian cane farmer doing. This is just some yokel that will sling it around every now and then, and the steel just might endure that little bit of use. Not because it's a well-made tool, but because the cross section is robust enough to handle the the work without snapping across.

He certainly didn't achieve anything worthy of note because he did everything possible to contaminate his results. The differential quenching media, unknown alloy and wretched heat treat.... ugh!
 
hello, yes it will work. for an explanation it is done just like the video. the only thing i would suggest is using a magnet to be sure the blade is at the correct temperature before quenching. a magnet will not stick to the blade when it is at the correct quenching temp. also i would suggest an oil quench, it will lessen the possibility of cracking the blade.

this is the answer i really need,thank you very much sir
 
Woodster, you're about 110 degrees shy of the quench point for 5160 if you stop at the point of nonmagnetic aren't you?

And, cangcimen, I'm trying to figure out why you even asked the question if you ignore the first two answers without asking MORE pertinent questions.

I hope this response is just a product of translation/language barrier. You should be in search of the most truthful answer... not the one that suits your purpose. I think woodster is being very generous with his info but at the same time, being very vague. The heat source in that video is not what you want. The tempering procedure in the video is not what you want. The pre-HT finish(looks like it was near sharp) is not what you want. You can HT a blade with simple means but the method this video is simply... not what you want. Without too much more effort you can put together a decent setup. Google "simple charcoal forge build", "washtub forge", "pit forge"... Don't use water to quench. Warm canola oil would be much better. Temper your CLEAN blade in a kitchen oven. There are many threads on this site with simple heat treat methods. Look for the ones where the majority of the members are agreeing with each other. Even then it can be iffy... lol.

Ask lots of questions but read the stickies as well. Most of this has been covered, extensively.

Most importantly... have fun!
 
It *could* work, but there is very little control here. I'd say there's more chance of it not working and the blade snapping off in usage or the edge bending over during usage. Possibly with injuries resulting.

Like Rick said, there are much better ways of low-tech heat treatment. There are a lot of dabblers on the Interwebz that do things no professional knifemaker would consider, even under primitive conditions.
 
thank you for the correction polish avenger. i should have wrote a shade or two brighter red after non magnetic.

Obviously worked for this guy. Definitely a crude job of it. May or not "improved" its hardness or temper.
Strictly on safety, he would have been better off grinding out that shape & start chopping without heat treating.

Yep. I can confidently say the blade is not hardened... and steel is probably worse off than it started.

Don't be scared to reply to a moderator... [cue ominous music]

They were once Members. Kind, contributing Members. Then Spark the Deceiver gave to them the Red Profile Name of Power. Blinded by their righteousness, they accepted without question, one by one falling into darkness. Now they are slaves to his will. They are the Moderators, Threadwraiths, neither humorous nor considerate. At all times they feel the presence of conflict, drawn to foul language, insults, minor spamming and non-sanctioned self promotion. They will never stop pestering you. :grumpy:

So, you're building a pit forge? Very nice. You can buy hardwood charcoal by the bag or just make a fire just off to the side and drag coals over to the forge area. Post pics!:thumbup:

If you have access to a larger drum, 30 gallon, or an oil drum, you can make your own charcoal.
Though you can use a paint can to make it as well, it would take forever to make enough to forge and HT a knife using such a small container.

It isn't difficult, and might be able to work out well for you.
Look up "Making charcoal" on YouTube for more info.
 
Haha. Off to the quote thread you go!
