There are several ways to make a knife. The first is to buy a ready-made blade and install it on the handle. This method is easy, but it often requires a lot of money and time to find suitable materials. That is why it is worth considering the second method of making a knife yourself, which is more affordable.

Sharpen and refine the plate of your blade using sandpaper. From the handle side, give the plate the desired profile that will correspond to the planned handle. All this work can be done in a few hours and you will have a knife that suits you.

Cover (wrap) the handle over the thread in several layers with a beautiful tape, rag, electrical tape, after lubricating the handle with glue. Don’t forget to leave a place for the fingers to rest; if necessary, file it to the desired shape. You can choose the winding layer yourself; here it is important to consider what kind of handle you would like to see and for what purpose the knife will be used. If you need a hard and rough handle, then river sand, sawdust, pebbles and other small objects can be placed on the glue.

Cut out wooden handles for the handle. Glue the overlays to the plate. Wind thread onto the glued overlays in one layer along the entire length. Such winding will not allow the pads to stay level without moving to the side.

Despite the fact that there are now knives on sale for almost every taste, many craftsmen prefer to make them themselves. Making a good knife is not so easy - for this you need not only the appropriate tools, but also a certain skill.


Instructions

First, create a life-size sketch of the future knife on paper. Try several options and choose the best one. Remember that a mistake at this stage can ruin all further work. Therefore, take your time and carefully consider the design and ergonomics of your future knife.

When designing a knife, do not forget that there are legal restrictions on the manufacture and circulation of edged weapons. The main features of a bladed weapon are: the length of the blade is more than 10 cm, the thickness of the butt is more than 2.6 mm, the hardness of the steel is above 42 HRC, and the presence of a guard. Your knife must not fall under this law in at least one respect.

Select the necessary materials for the blade and handle. The blade must be made of high-quality steel, the handle can be made of wood, plexiglass, PCB, horn and other materials.

If you plan to rivet the handle halves, mark and drill holes for them in the shank of the workpiece. Then process the future knife on an electric sharpener, giving it the desired section, tapering towards the edge of the blade. If necessary, sand the knife sequentially, from coarse to fine sandpaper.

Temper your future knife. You should know that proper hardening is an entire art with its own professional secrets. It is enough to heat an ordinary high-quality household knife until it turns crimson and lower it vertically, tip down, first into mineral oil until tarnish (rainbow) colors appear, then into water.

Make a handle. If it is made of two halves, cut them out, rivet them to the knife - they can be made from an aluminum rod - and process them on a sharpener. If the handle is solid, drill a hole in it, then fit it onto the shank using epoxy resin mixed with sawdust.

Make a stacked handle from horn, tree bark, colored pieces of plexiglass or other suitable material. Place pieces of suitable size onto a shank, at the end of which pre-cut a thread. Lubricate the pieces to be attached with glue. Screw a bronze or brass head onto the shank with a hole drilled in it and threaded with a tap. Process the assembled handle, giving it the desired shape.

The final finishing of the knife comes down to fine-tuning its shape and proper sharpening. If necessary, make a sheath from two wooden or plastic halves, cut, taking into account the allowance, to the shape of the blade. Make a notch in the halves along the contour of the blade so that it fits in with little friction, then glue them together and cover them with leather.
