Before drinking , and now cuts , or how to make a knife out of a file ?

What to use as a template?

Knife Making of a file begins with a sketch drawing.Draw a shape of the blade, the handle, the way of its fastening.As a result, the paper must be drawn is that you wish to obtain in reality.As a blank file is used, which can either buy or use the old tools.Material of a file - a carbon steel U10 , which has a hardness 57-58 HRC .These qualities make it strong, with good cutting qualities, easily transporting a heavy load and do not crumble.

alternative would also serve as a mechanical saw that is used for sawing of rails.Its strength is even higher than that of a file.These two materials are equally ideal for the manufacture of knives at home.However, the old nail files are more accessible stuff, so we will rework technology is one of them.

Important!When carrying out the production of the knife all precautions must be observed strictly.

Knife Making of a file - start working

To make a homemade knife from a file, you will need the following tools and materials:

• file (it is better to use a Soviet);
• handle material (wood, plastic, ivory, etc.);
• shoe polish and wax;
• gas stove or other heating device;
• machine vise and Bulgarian;
• magnet;
• sandpaper;
• material for rivets, best brass;
• adhesive for metal and leather.

Now you can start working.The first thing you need to perform firing.For this file is heated in an oven for six hours and allowed to cool there.This is done to ensure that the metal has become similar to the material, as it was before processing factory.You can also warm it in the fire and leave to cool on hot coals.At home, it is done on a gas burner.To do this, the cutting part of the future of the knife is placed on it, and on top of the heat shield is made of metal.He must not touch a file, but to be a centimeter above.On top sprinkle with salt harvesting, which is in the process of heating will melt.The time needed for the procedure is the same as in the previous embodiments.

Next cut off all unnecessary, and the workpiece is brought to the drawn by earlier forms.Then drilled rivet holes, after which there is hardening of the future knife.To this end, the workpiece is uniformly warmed to a single color incandescent.Handle tempered optional.To find out whether it is tempered, it can be a magnet as soon as the metal stop magnet - it is ready for further processing.

Note!The correctness of hardening can be checked, having the workpiece on the glass: if done correctly, it will crack.

knife from a file is ready - final action

main work is done.Now runs a vacation - the process of changing the properties of steel, which is to reduce its fragility, which the blank for two hours, warmed in the oven.This is followed by grinding, ie the blade surface brought to a smooth and smooth condition.The next step is to etch metal ferric chloride, thereby forming the oxide film, which will protect the product against corrosion.

Note!If there is no etching of ferric chloride, it can be used instead of lemon juice or vinegar.

being finalized sitting on the handle rivet, before which it is attached to the base.Knife sharpening best manually as scratches are not dangerous to him, unlike overheating during sharpening inept machined.Then the blade is rubbed with wax.Instead of lining the skin can be used to handle, which is uniformly wound on it, and then use the shoe cream is brought to a homogeneous state.
