100 thoughts on “A Knife From A FILE!? MYTH BUSTED!

  1. Little thing we did not clearly mention folks!
    The quality of a file knife is highly dependable on the heat treatment and the steel the file is made of. Often though it is hard to figure out what steel they are.

  2. Love your guys' humor it's great to watch and you should have sued that company for using your videos in their commercials

  3. Mickey, your camera work is lazy. The text fillers are unintelligent. And Maarten is ugly. And I still love all your video’s!? amazing!?

  4. Hello, novice blacksmith here to shed some light on this subject.

    You used a rasp, which is usually not as hard as a metal file and sometimes only case hardened, meaning only the outsides are hard steel and the inside is soft so you get a soft edge when you sharpen it.

    Metal files make great knives if done correctly, sometimes a normalizing cycle and heat treat (hardening and tempering) is in order but usually just tempering will do the trick.

    The big mistake here is using a rasp, they're shotty in steel quality where metal files are usually good high carbon steel, try the test again with a Nicholson file and you'll see the difference

  5. if you use a short piece of file steel and make a 3/4 inch blade it will make a great knife anything longer and you are asking for failure i made a couple decent skinners 20 years ago and they are still going strong.

  6. thank you dudes, I have been telling people for years that it depends on the original composition of the tool steel used and in the heat treat, yes you can make a knife from a file or rasp but expect it to fail

  7. Great video, poor knowledge in the difference between a file and a rasp. You are correct however in your comment about proper heat treating being a major factor in the toughness of the steel. Personally I would fold and/or cut and layer my stock before pounding it out to shape. It would not be recognizable as having been a file once I have made it into a knife.

  8. heat the tang to critical temp quench in water…put in a vise and break the tang off…you can tell how it will harden then…I've made a lot of rasp knives and the performance is excellent…..

  9. Why would you cut rope on a steel plate on top of a wooden stump? Why not save the rope and rub the edge against random pieces of mild steel? Plus the video shows that you pressed the file knife into the steel allot more than the O1 tool steel knife. This a very shitty test.

    Besides all of that most files are made of W2 or 1095. Which is all in the same category as "simple ol O1 tool steel". They're all high carbon tool steels. So you are comparing lemons to limes or assholes to arseholes. It's the same bloody thing.

  10. you prove nothing by cutting paper after abusing the knife if you do not show it could cut the paper to begin with. how do we know it was sharp enough to cut the paper to start? you did not show us. also that was not even a file, it was a wood rasp and those are made from a mild steel not high carbon steel. second question, why would anyone buy a knife not knowing what it is made from?

  11. Literally about to make one from a file! I haven't watched the video yet, so have they saved me lots of hassle? We shall see……..

  12. Different file companies make their files from difference to you most makers from case-hardened but the good files are made from W2 I have file knives and they don't lose their Edge I have had something other kid and I've never sharpen them

  13. I love you guys, all of your videos are great, but man oh man this one might be my favorite haha I was laughing the whole time

  14. 1. Files and rasps are very different. That knife is made from a rasp, which probably has a mild kind of steel and no tool steel at all, as it is a woodworking tool. If you go making a knife out of a file, go for a metal file to start with.
    2. Even when you use a file for the blank, you should know the process the file maker employs. Some files have a soft core of mild steel covered by a hard steel shell and are surface hardened. Such a file would not yield a proper edge when you remove the shell during the knife making process.
    3. Files are for birthing the knife out of the blank :-). If you want cheap but consistent blanks, go buy some leaf springs from your local salvage yard.

  15. That seems like a very poorly crafted knife, and may be a file that was case hardened rather than a quality steel, another issue is heat treat, or lack therof. I feel like that knife was never heat treated and just cut with an angle grinder with little regard for the heat of the blade (passing 400 deg F will wreck the knife)

  16. Files are usually case hardened and not suitable for knife making. The exception being farriers rasps, which can make good knives as they are made from higher carbon steel.

  17. Hey guys great video !! What’s the name of the song during the sharpness test artist and song title plz !

  18. I’ve made countless file knives. I’ve had people offer me up to $300 for some of them. My best file knife held an edge longer than my best d2 steel knife and was more durable in general.

  19. You should know that Buck Knives originally made their knives from old files. Look where they've come. Check out the history of Buck.

  20. FIles vary in hardness, I had one so hard that it broke in half. The Nichols old files make good knives, not brittle and sharpen easy and stay relatively sharp with use. They are after all high carbon steel so they act like that. They will tend to rust if not cared for. I left the file on the side of mine to sharpen my axe or create sawdust. They also throw great sparks. I would rather have those features in a knife than a super steel that is hard to sharpen, mediocre with sparks and can't sharpen my axe and I bought the file at a flea market for 50cents.

  21. You never just take a file and cut a knife out of it. You have to anneal the knife and redo the heat treat to a more knife appropriate hardness. If you really want to test a file knife buy and Anza knife and test that. I think the result will be different.

  22. I feel would feel bad bashing mikki in this comment, because he is so fragile and weak minded. See what I did there.
    Hit it.

  23. I disagree because you have many knife brands that use the same steel for their knives and as a knife maker its all about the heat treat and the blade angle of the knife that makes it cut.

  24. me first knife I made was from a file! after i worked it, it was heat treated! you can sharpen it pretty sharp, but it is NOT ALL THAT! its O.K. to use for light stuff and to pass on to grandkids; you arent gonna beat it up, for it will break like a file!! Ha Ha Ha!

  25. why making such big knives from big black files and rasps – just try a knife made from a nice shining nail file …
    well, joking, of course.
    who would like to convert a good nail file into a bad knife …

  26. i noticed you where using a rasp file. I have drilled thru a rasp file on my drill press with a high speed drill bit. Try this on a regular steel file. They are brittle but hold a much better edge.

    You cannot drill through them with a cobalt bit exept at the tang. Tell us what you think of those.

  27. Too many variables to claim "myth busted" and a lot of flaws here already called out by other commenters. Sounds like you guys are just trying to downplay these file builds.

  28. LOL, you ain't doing it right? Gotta get the spirits involved with that knife. ;)Thus, it hardens out.
    Just joking about, I wish some of the tribes used it for the humor about it.
    (Joking from a Native American viewer XD)

  29. Agree and disagree almost knife maker will tell you that if you literally go to the store and buy a metal file and make a knife out of it it's not going to be as good now if you go to a place like a flea market and buy a really old file and make a knife out of that that's a good material to use almost any knife maker uses that as a budget material

  30. That sharpness test was total bull, the reason the knives became dull was because you dragged them across a metal plate, you just dragged the file knife across the plate more

  31. As a blacksmith I can point out many things done wrong, but youtube know it alls can do this for me……

  32. I've watched every video you guys put out and I see no large knifes remember a big knife can do anything a small knife can do……. I carry a 18 inch bowie with a 11 3/4 inch blade 1/4 inch thick and it has never disappointed me ever …… you should make a video about large knifes please

  33. Regarding your video on myth busted making a knife with a file. How old was the file. Modern files are case hardened not high carbon steel. The hardness is less than 2mm deep so no good for knife making. Old files are made from high carbon steel so can be hardened and tempered to make a knife that will holds an edge. Files are 1 to 1.25% carbon. 1095 has 0.9 to 1. 03% carbon therefore files are harder than 1095. If heat treatrd correctly. like to hear from you.

  34. The only reason it's hard to split wood is because its serrated on the sides so it causes friction on the wood

  35. I used this video as inspiration to make my own very first knife! I just uploaded the video. Check it out if you have time. Would love to have your feedback

  36. Im sure someone has already made these points but first thats not a file. Its a rasp. Rasps and files are not made from the same steel. Plus we have no idea of the process used to make the knife. Did they make the knife from the rasp as it was? Did they anneal it. How hot did they allow the blade to get while grinding before cooling it in water? Did they cool it at all? Did they temper it? If so what was the tempering process. From watching the video i have to say that the knife i made from a rasp holds an edge a decent bit better than that one. But mine does not come close to the edge that a few knives made from rasps by people with much skilled people than myself. So in closing your video proves nothing other than you two are quite capable of at least making a pointless video amusing. And for that ill give you a thumbs up.

  37. Things you didnt mention. Did you aniel the file b4 making the knife? Of idnyou didnt, did you make sure not to over heat the file while making the knife? Also what kind of file did you use? Alot of new made files are case hardened now a days which means when you make a file knifr from a mew file they will almost always lose sn edge super quick compared to old vintagr 1095 steel files. Just a thought

  38. for knives you must used old files, if you buy a new one to make knife out of it, will not ending well. old files are all hardened, but the new one 20 years old or 30 years old are not good for knife making, especially the cheap ones. new files are hardened only on surface.

  39. wow this was a bs vid…funny but not accurate. next time mention in the vid what you said in the comment section…thumbs down from me sorry

  40. You guys never gave this a fair chance and need to redo it. After shaping the file to a good edge, you need to heat-treat it ON VIDEO, get it a 2nd bevel, and THEN perform the tests. 1095 is worth shit after reshaping because of the heat it endures. Hook up with me if you want to figure out how to REALLY make a file knife, and not a shank.

  41. I’m not trying to be a di/ck but these guys really don’t know what they are talking about in any of their videos

  42. If u make a knife from a file, you have to reheat treat it again. The grinding process will create heat destroying the treatment previously put onto the steel. You did not Say whether you reheated and quenched the steel after making the blade. This could have affected your results. The tool steel used in files is usually fairly decent hi carbon steel.
