WATCH THIS BEFORE YOU MAKE A KNIFE WITH A FILE
The simple guide to making a knife with a file.
Theres a lot of different types of files and mystery steel. In this video I go over the different types of files I was able to identify. And how to find out what typeof file you may have. File CAN make great knives, however choose the wrong one, and you’ll waste a lot of time! File knives are a great place to start your knife making journey. This video is a great companion video to all the file knife making videos out there. I also have some file knife making videos on my channel, be sure to check them out! Thanks for watching!

Be sure to check out my recommended product page on my website where I have brief reviews on things I use⬇ www.outdoors55.com/shop This is a work in progress and is updated frequently🙂 IMPORTANT⬇ This video is a brief summary of the mystery steel file world! I tested over 30 files and did almost 300 hardness tests. Testing hardness at the surface, as well as at various depths beneath the surface, all the way to the middle of each file. I also tested multiple heat treat coupons for each file, testing both water and oil quenching. This video is a good summary and overview of my findings. Keep in mind your results may differ as file manufacturers may adjust their steel and heat treatments over time. If you think I missed something (im sure I did) leave your thoughts below. The idea here is to learn as we go, and any info is good info👍 I left a link to a through hardened file in the description (I tested 3 of these with great results). Thanks for watching!

@mrhoogles 11 месяцев назад

just for the record, probably should have mentioned, when hardened steel breaks, it also has a tendency to send shards directly toward your eyeballs., also... why is that?

@OUTDOORS55 11 месяцев назад

I did mention that, and included a link to a video showing how dangerous breaking hardened steel is. The link is up on the right corner of the screen when I mentioned it.🙂

Very beautiful presentation. I guess i was lucky (and i used an already broken file with a nice fine structure break) for my first wood carving knife. Still my favourite tool for carving spoons after a few years. I guess it's time to make a proper sheath for it😉. I'm slowly getting into blacksmithing and i hope to make my own spoon knife. The first one i made was too thin and had a crack so it broke 😒. But i made it a couple years back in a kitchen, during winter time, heating up that file in our central heating coal stove😊. And that was fun! If my mom lived, she would probably chase me with a broom from that kichen. Dad was pretty ok with it and smiled a little. He had blacksmithing lessons in his school time.

Great video. Back in the mid 50's dad made my first fixed blade knife out of a file what kind what brand name I have no idea , I did all the roughing grinding under dads eye all I can remeber is him telling me don't let it get hot . It has a scandi edge all these years later it is my favorite knife especially for skinning it has a 4-1/2 inch blade 4 inch stacked leather handle which by the way other than being bite darker is just like new All my leather gets oiled every new year whether it needs it or not. Also keep in mind I've never tried to bend or shot it or hit it with a hammer . it just cuts every time I ask it to skinning or wood for kindling never batoned with it just cut things . Happy Trails Uppps forgot I HAD TO MAKE A NEW SHEATH FOR IT ABOUT 10 YEARS AGO THE ONE I MADE FOR IT BACK WHEN i WAS A KID OUT OF ONE OF GRANDPA'S OLD BOOTS FINALLY WORE OUT AT THE BELT LOOP . hAPPY TRAILS KEEP ON MAKING THOSE SMART VIDEO'S.

wow, I did not expect this video to be even remotely as thorough as it is. you really did enough due dilligence to produce reliable information (certainly better than I would do), rather than just making like three blades and then guessing where the problems are and leaving the viewers to contemplate on how reliable your semi-intuitive judgement may be. you've got a hardness tester, repeatable heat treatment, and a big enough sample size to categorically exclude wood and hoof rasps and files, which is the most useful sort of information for the average viewer who wants to make something from old files that works the first time. thank you for making a very useful video!👏🙂

@coreypetttit 10 месяцев назад

Good stuff as always! One of my knife maker friends said they can make any steel hard( case hardening) so I should look for the older American made files. Most new files today suck. Auctions are usually your best bet for finding old files for cheap!

@johncannon3593 10 месяцев назад

Excellent and informative video. I have had good luck with the farrier's rasps I get from my farrier, but he buys the more expensive ones (>$30 each). I always test them before use though, by cutting off the tang, heating, quenching in water, put in a vise and whack it with a hammer. They snap and demonstrate good grain structure. I am not giving the brand, because that brand also makes case-hardened rasps, so it is more important to test them, which I do with every file except duplicates from the same lot (lot number given on the rasp). With that said, I also ALWAYS do a full heat treatment on the finished product (with an anneal before working) using a fast quenchant (50). I would not try to simply grind them and use original heat treatment. Caveat: I do not have an HRC testing device. I go by file skating and Japanese testing files as well as experience showing good edge retention with use.

@joebrown5967 10 месяцев назад

Very good video, just remember if your rockwell testing on case hardened material your likely to push right through the hardened layer. Especially on the the c scale. The thinner the layer the less weight you use to test and change the scale to b or a. There are many ways of testing treated steel and its best to read up on what is the right one. I had many years of treating different types of steel and the accompanying testing involved....its an art in itself.

I do a rudementary heat treatment test of a small chunk from every file or other mystery steel I intend to make a knife from. Literally nothing except for new steel with a known spec is standardized enough that you don't have to test it, and even that should be tested occasionally.

New Nickelson not even in the running. Old- was great stuff. Since they outsourced to foreign soils they got really sorry. Ran a wooden boat shop for a dozen years and bought a lot of files, sharpening scissors (Fiskars) made of really good steel, and would go through a file a week. Then they farmed out and the files would not cut- just skidded across the metal. Went to belt grinder, absolutely had to. Where do you source others? I like in the boondocks, so any help would be appreciated

@TylerSnyder305 10 месяцев назад

@@wrstew1272 yeah, I've had decent luck with them but they don't last anywhere near as long. About 10 years ago I finally wore out an old Nicholson black diamond file that belonged to my grandfather, and I have no clue how long he had it. I have yet to spring for them but have heard the German made Pferd files are the best you can get these days.

@TylerSnyder305 10 месяцев назад

@@OUTDOORS55 it's not really a myth necessarily. I've had decent luck with the current ones that are made in Mexico, but they were made in Brazil before this and a lot of people were very unhappy with the steel quality/ longevity. I've been happy enough with the current Nicholson files, but maybe the steel is different because they do not last as long as the American made Nicholson files would. I've used both and they just don't.

This becomes even more of a pain in the ass when the files you are using are 6+ decades old and many of the manufacturers have gone the way of the dodo. Though, in my experience, most of them have been through hardened. Yet another reason I’m glad my grandfather passed on to me a lifetime of experience and knowledge. He first explained grain structure to me when I was still in middle school.

@brightargyle8950 10 месяцев назад

I've been making file knives for the last few years and learned most of the things you mention the hard way. I never touched rasps, I knew they would be no good for a knife, for the most part. I did buy a large file to make a medium bowie and got my heart broken when I realized it was case hardened... much too late into the build. I have learned to tell the difference in hardness in how the grinder takes material off, softer comes off like crazy, it feels weird in comparison to a nice tempered file. I do not re-heat treat my knives, I do not have the facilities, I temper the file and then carefully grind down from there, cooling in water regularly. This takes time, but has the benefit of leaving me with a knife of the proper hardness without overmuch worry. I do the ghetto method of annealing for pins in the handle, works like a charm but I wrap the blade with wet towels and monitor the process very carefully, watching the color of the steel to tell me when it's done. (Usually dark blue.) I really appreciate the work you put into this and wish I had had access to it years ago, its good info! File knives are great when made right and can give you a nice, usable blade as good as many manufactured ones. (If not better.)

Lots of good information here. I honestly don't understand the compulsion to use mystery steel to make knives. The appeal of free seems to be too strong for some people to resist. STEEL IS CHEAP! 1075-1080 steel is very forgiving. It's easy to heat treat and A 60" .187x 1.25" bar can be had for under $25. That's enough steel to make 5 large knives or 7-8 medium knives. You can quench it in vegetable oil from the grocery store.

During C crises I made paper-sheets for all and wood handles for some on my files and rasps (about 25 large ones, 10 medium ones and 20 very small ones) to preserve them longer. handling these I can somewhat tell its different materials in them, shine, rust, sound and handeling on material etc. And especially newer rasps seems to be poor "mystery metal" as they go dull quickly (hardly sharp to begin with). I do save the dull ones in case I would somehow sometime get access to a forge. But this video of yours have made believe I shall not save the rasps., Thanks again.

Solid information, per usual. Much obliged. Hey, if it’s not too much trouble, could you do similar tests for 3 or 4 manufacture’s of drifts, punches, chisels, and gouges? And if you could have that up by Wednesday I’d really appreciate it. [I’m kidding, I appreciate what you do, when you’re able to do it. I’m not looking to bury you in tedious repetition in the hopes it means I never have to encounter variability in my work. I learn from what you post, but if I encounter something you haven’t talked about yet - then it’s on me to find the solution. Keep being awesome. Cheers!

Great video - very clear (to me at least). Yes, those relatively inexpensive rasps are "compositionally" hard. they have a bunch of carbide or whatnot in the steel mix, hence the grain. They are reasonably wear resistant, but not very tough. I believe they are also impressed with the their teeth while in the red hot condition, and then quenched fast. The expensive hand made woodworking rasps are through hardened, because the teeth are cut cold, then the entire rasp is hardened. That said, who wants to make a $150 file into a knife? There are so many worn out steel cutting files available. I was given a dozen 12" lathe cut files 30 years ago, and I still have a few of them lying around for future projects. I don't typically make knives, but I do make other odd cutting tools for weird applications, and the repurposed old files are a pretty good choice for something I may only use once or twice. Thanks for your hard work!

Exactly! Thats the tough part about using files. The manufacturing method greatly influences steel type and whether it's useful as a knife. Thanks for the input!

I think I’ll limit myself to power hacksaw blades, I’ve seen them used in factory packing rooms, both on cardboard and flesh, they work well for both and the packing tape handles are easy to make !
