How to make a Bushcraft knife
With just a handful of items, making a functional bushcraft knife of high quality is an easy task. Dependent on the metallurgy equipment and skills that you have, the process of making a bushcraft knife can prove to be exhausting as well. Hence,the first step to start making a Bushcraft Knife is with collecting the things you need to make it on your own.
What you should prepare
· File: Even an old one will do!
· Hardwood: for making the handles of your bushcraft knife, apart from wood, you can also use Rubber or plastic as well.
· Oven: For tempering the blade, you will need an oven that can raise 350- 6660F
· Forge: you can use another fitting substitute to burn the coal in;
· Coal: For heating up and many other metallurgical processes of making a bushcraft knife at home.
· Epoxy Adhesive: For the final assembly of the knife, use 2-Sided Epoxy adhesive.
· Oil: Protects the wood and most importantly, for quenching the blade.
· Hacksaw: To cut the blade as well as shape it, you need a power saw or a hacksaw;
· Clamps: While filling the grind of your bushcraft knife, clamps better the procedure.
· Caliper: Beneficial to the stage of profiling the knife, also sued to mark or pattern the rough outlines;
· Vice: When filling the grind or creating the bolsters, you must secure it within the vice.
· Lubricant: Used to have a smooth drilling on the file without friction;
· Drill: In order to drill the file as well as the handle, you must acquire compatible drill and nails.
· Hammer: Apart from beating the file, manual hammering is required to straighten the file on the bushcraft knife at many places.
· Tongs: For use when shifting the hot blade during knife-making;
· Scriber: To mark the pattern, you can use a permanent marker or a scriber.

After collecting your choice of raw materials to make a bushcraft knife, the next step is to find your comfort zone and start making the bushcraft knife. To do it, follow the below 8 steps on DIY: Making a Bushcraft Knife.
Design the dimensions of your bushcraft knife
Make a compatible bushcraft knife prototype that you like. Also conduct spark, hardness and break tests to check if your steel is susceptible for the knife you have in mind.
Use a permanent marker or scriber to mark your choice of dimensions from the design, onto the file.
Preparing your Files
Annealing your knife is mandatory because, in order to work on your file, you need a tool that is harder than the file. As the better choice is to decrease the strength of the file, you must heat the file at an austenitizing temperature, preferably until it is red-hot.
As the files would lose its magnetic properties due to the aforementioned process, heat it up after 3-5 minutes. Repeat the heating and cooling process for a few times after.
You must superimpose the print-out or prototype of your bushcraft knife onto the annealed file, now. Then, enclose the file in a vice, add oil and make a vertical cut on the knife with a three-tooth hacksaw or compatible power tool.
Also known for refining the file conforming to the prototype, filling to eliminate the rugged edges due to the hacksaw cutting is an important stage of DIR: Bushcraft Knife;
- Cross-Filling or Straight Filling: Filling Direction- 900, Work-piece 1800 within the vice.
- Draw Filling: Used for the fineness of the surface-finish of the blade, it flattens the edges.
· Sharpening the Edge of your Blade or Grind-Making
Denoting the shape of the knife’s cross-section, the grind is also referred to as bevel. The golden tip is “Less material do you have behind the edge with a steeper grind, sharper your blade will be”.
To get started, mark the grind boundaries on your knife and calculate grind width b using,
b= T (2tanα) with a thickness (Blade) as T of the angle α, with a permanent marker. Secure it into the vice and begin filing in the grind equally on both the sides.
Hardening and Tempering
Conducted through the process of ‘quenching’, hardening the knife up to austenitizing temperatures is necessary to harden it. As the file’s color denotes the temperature it was heated on, and it is ideal to heat the file up to 3500-6600F for up to 1-2 hours in an oven to temper it.
Bolstering and Handle Making
Take the remnants of the file and make two oval bolsters, with the front bolster in rectangular shape and the rear one, as a smaller rectangle. To make the handle, use wood or rubber to after marking the location and size of bolstering needed. To polish your blade, use a refined shaping and grit with sandpaper.
Determining what type of file you need for your bushcraft knife will help you understand that these differences of the steel will also judge the firmness, sharpness and efficiency of using the knife. Knowing how to make a bushcraft knife on your own is the stepping stone to efficient DIY Metallurgy!
