This article documents the process of me making my first bushcraft knife. I stumbled upon a superb video teaching you how to make your own bushcraft knife with relative ease using easily available tools and materials. The steel could be an old recycled file and I managed to get all the tools needed for under a tener. Thanks to GreenPete and his generosity in giving his time and effort to share his knowledge, he passed on to myself and a friend the knowledge to make our own knifes.
This article will progress and show you the steps of progress as I worked on creating my first knife, however, if your interested in learning how you make your own knife, feel free to first watch the same video that inspired me:
This is the video guide that inspired me to do this project, have a watch its very educating, note that GreenPete kindly offers this video for download in full DVD quality, the download link can be found below the videos.

My Project
Inspired by the video, a friend and I started planning; thinking of materials and tools. Neither of us had any prior knife-making experience but thanks to GreenPete's video, we were confident that this project was feasible even for us! We had to gain tools, knowledge and experience along the way so off we went...

Materials & Tools (Not Much!)
I had no real tools to start, but the video taught me I wouldn't have to spend a fortune on fancy equipment and I could use recycled materials. So first up I thought about getting a tool I considered to be one of the most important used in the video, the Angle Grinder, it does most of the shaping and hard work. I gave my father a shout and told him to keep an eye out for one (seeing as he's a builder), 2 days later I was kitted with a second-hand angle grinder that was like new that cost my father 3 or 4 pound which he paid and kindly gave the grinder to me! So far free.
I picked up a hammer, sandpaper, wet & dry paper & a spare angle-grinder disc or two at a local show all for about £5-8, dirt cheap. Regards a working area; I had no garage or work-bench, just the small space of a balcony which became our work-area. |
This is the old, rusted file that I had to start with and turn into my first bushcraft knife:
*Note: If you plan to follow this project in a similar way and will be using similar tools, please equip yourself with the right safety gear. A £2 file or a £4 grinder can easily be replaced, your fingers or eyesight cannot! Please, please, please take your safety seriously when working. Goggles will be essential and gloves are highly recommended. Safety equipment is available to the right of this page. As soon as we saw GreenPete's video myself and a friend were discussing plans for our own homebrew forge to do our heat-treating in. We quickly determined that between us we had enough spare kit to make some chambers and rig something to do the job. So onwards we went... |

The Forge
We started to design our own small homebrew forge which we would use to do the heat-treating of our steel files. To the right you can see our first crude idea, you might laugh, funny as it looks but it worked well in the end.
Myself & Scott tinkered for hours in my living room with different design ideas and pieces of kit, trying to workout what best recycled parts would be best and fitting them together and eventually we came up with a little forge that despite its looks will reliably heat a thick file to red hot in just a few minutes. It worked very well.
On the right hand side you can watch a YouTube video we made introducing you to our homebrew forge, it might give you a better idea of how it works and you get to see it in action.
The hairdryer fan we used was infact a travel-hairdryer, so probably not even as powerful as most of the motors in normal ones, but this fan combined with one of those variable voltage-plugs, the ones where you can slide the voltage up and down, this let us have good control over the speed of the fan.
If you make a forge similar to this design using recycled parts, make sure the top-pan (a old thick wok in our case) is fairly thick metal, a few millimetres at least, you don't want it to melt or degrade away with the intense heat of the forge. The wok we used (shown in pic) seems to do the job just fine, I've used it numerous times and for long periods and its still going strong.

Heat Treating (Annealing your steel)
Thanks to GreenPete's video-guide, he taught me the basics of heat treating my steel file. Previously I knew nothing about heat-treating steel, but now I know first I needed to anneal my file to soften the steel so that it can be worked with and shaped etc.
How to Anneal / Soften Your Steel
To anneal your steel-file raise the temperature of the file up to 800ºC (glowing red-hot). You can do this by lighting a fire, let it burn well and get a good bed of embers, put your file into the fire then stoke it right up with plenty of fuel, keep it going for about half an hour, then the important thing to do is to allow the fire and file to cool down very slowly, this will allow all the carbide to turn back into carbon and then the file will be workable.
When your fire has gone out, remove your file and if there is any good charcoal left you may want to keep it for later use with your forge.
To test if you have successfully softened your steel you can test it by trying to file or drill a part of it that you wont need to use latter, this will be a good indication if its worked or not, see GreenPete's video for more info on that.

Click the image on the right to view the full size template. Save the full size JPEG template and then open the file in Photoshop. Photoshop seems to print it at the correct size. Yet again thanks to GreenPete I had a lovely template to follow! My File was just a fraction to small to follow GreenPete's template, so I adjusted the measurements slightly I used a small piece of ply-wood to make a wooden template of the knife which I could use as a comparison when working on my file with the grinder. Now you have your template ready you can go to work on shaping the steel with your grinder or files. << Back to Menu or carry on reading below!Working the Steel File
As you can see in the above picture; so far I am using a ply-wood template and a cheap hand-held grinder that I picked up second hand for around £4. Using a grinder was fairly new to me, so I just worked slow and safely, taking my time. Wear eye protection, watch your fingers! And don't have cloth or flammable materials nearby (you'll be creating lots of sparks!).
Again, working slowly with nothing more than the hand-grinder I managed to cut the basic knife shape out of my steel-file. Once I had the basic shape, I decided to clean up the sides, removing the file-teeth and rust. I did all this with the cheap grinder, a bench grinder and sander will probably make life easier if you can get access to one. If your starting like I did with no previous knowledge on using grinders etc. please seek guidance from someone who is experienced.
As you can see above, I have used the grinder to form the shape of the knife, take off all the rubbish on the surface of the steel. If you are using just a hand-held angle-grinder as I did, this will take you hours of work. Next I took a trip to my father's so I could borrow his hand-drill, and drilled three holes through the steel, for my handle to be fixed to later. I believe the holes I made were 4mm in width and I had ordered some 4mm brass-bar online.
You can see in the above picture that I have started a single bevel edge for the blade, again I just did this mostly with the hand-grinder, no doubt there is a better tool for creating your bevel edge, a bench-grinder etc. but I only had a hand-grinder and a dremel to work with, I was pretty pleased with the results so far. Looking back on this; your bevel-edge is potentially the most important part of your knife, my angle was to steep, I would recommend starting the bevel edge with the angle-grinder but then to setup a file-jig like GreenPete did to get a more precise, consistent angle for your edge (approximately 22 degrees). There are also specially made equipment for helping you to create your bevel edge.

Finished Product
I am happy with the outcome of my work, considering this is my first ever knife project and I had no prior metal-working or even hardware skills I think I have done well.
So how's the Knife? It looks the part hey! Unfortunately it doesn't seem to be the best Bushcraft Knife I've used. I've sharpened it and it seems to work, it'll shave wood etc. but it just doesn't seem to perform as good as other knives, yes thats right a £10 Frost Mora cuts a lot better!.. there I said it
Im pretty sure this is because the bevel-edge starts too low, to close the cutting edge, which inturn makes the angle of the bevel edge to high, the blade essentially widens out too quick a bit like an axe blade, meaning it will cut, it'll just take more force and effort, so seemingly it wont cut as easily and efficiently as a thin drawn out bevel like on a frosts mora etc.
Im not too bothered at all, 'He who never made a mistake never made a discovery.' For me its been an enjoyable, learning experience and I have GreenPete to thank for that.
Have you completed your first knife-making project?
Let me know how it went! Send in your photos or comments here.
ignored for now!
01 ground flat stock
tool steel
high-carbon steel
harden and temper the blade.
high carbon steel, 01 ground flat stock ready for working, old metal-work file which will need softening first.
Does anyone have a downloaded copy on DVD they would be willing to sell me?
I would be more than willing to make a donation or pay for same.
Can anyone help?

Do hope you succeed in refining your device and develop one for the open market.
I be glad to buy one of your knife, however I'm skint at present.
''A Great Knife has a Great story, and your First Knife is a Great Knife.''
I will give it another go at some time,when time allows CHEERS.
I also read that the angle of the blade behind the edge should be less than the edge. 20 degree bevel if that's the word and a 22 degree edge for example.
i keep losing my knives all the time, i even managed to lose a german ww1 folding knife!!!
probably in a field far away now!
think i might have to make a few of my own soon.
great stuff.
pat
Really like the simplicity of your forge design, was thinking of doing it myself, now that I've seen how it can be done simply and without too much expense I'm definately going to give it a go, will let you know the results as soon as I get round to it!
