How to sew a knife sheath

Any knife with a fixed blade, designed for outdoor use, without a scabbard loses a significant part of its functionality. It is inconvenient to remove it from a backpack, and in a pocket of clothes it generally becomes traumatic. If the knife with which you are going fishing, hunting, mushrooming or camping, has no “clothes”, you can do it yourself. My task is to sew the sheath for fulgang without a specialized tool and from available materials. The length of the knife is 250 mm, and the thickness in the butt is 4 mm.

  • Leather. Cheprak vegetable tanning 3.5 mm thick - trimming from an old suitcase for tools. The sheath of such leather does not require additional elements of rigidity.
  • Thread. A shoe waxed thread was bought sometime in a haberdashery shop.
  • Wax. We will process the ends of the skin. I use carnauba (palm) wax - the most refractory and non-greasy to the touch. It is sold in the form of flakes in cosmetic stores. Alternatively, suitable technical paraffin (candle) or beeswax.
  • Cobble screw.He will play the role of fastener. Instead of a screw, a spare button from a jacket or a raincoat is suitable. Tools
  • Shoe Knife.
  • Carbide-tipped caliper for marking. Instead, you can use a standard drawing compass or meter.
  • A ballpoint pen.
  • Contact adhesive.
  • Two gypsy needles.
  • Pliers.
  • Drills with a diameter of 1.5 - 2, 4 and 5 mm.
  • Bench-type boring machine.
  • Belt sander.
  • Cloth circle.

Marking and cutting of parts

By design, the product will resemble a sheath for a NKVD finca. We put a piece of cheprak bakhtarma up, and on it - a knife. This will be the front part of the sheath.

Carefully draw the outline with a ballpoint pen. Mark the line where the handle begins, and align the “failure” from the butt side. Put 10 mm on the caliper and draw two lines using the drawn outline as a copier. We evaluate the result, circle the handle and, if necessary, adjust the form manually.

Pay attention to the position of the knife! I make the sheath under my right hand,and if you are left-handed, turn the blade to the other side, that is, mirror. We cut the outer contour with the shoe knife. Particular attention should be paid to the line of the mouth, so that the handle adjoins it without a gap. Then we make the same detail - the spacer, but inside it we cut internal lines. It will form the internal cavity of the sheath and protect the seam from undercutting. When overlapping parts, "tails" spacers should protrude from the side of the mouth. They are cut after gluing.

A shoe knife must be well sharpened! Cut through each line with minimal pressure in several passes. On curvilinear sections work only with the tip. Lay the skin on a wooden base. Gluing and contouring We assemble the front part with a spacer on the glue. We control the width of the cavity with a blade.

The next part is the wrong side. We mark it so that the bahtarma is in the cavity of the scabbard. The side of the blade follows the shape of the two previous parts. The part on which the handle lies lies randomly.The main thing is that the back should not protrude beyond the sheath. Then there is enough space for the strap, which will fix the knife, and the suspension.

Glue the wrong side.

Cheprak - a thick and tough material that is almost impossible to cut without errors. After gluing, the ends of the sheath will be uneven. jpg "style =" max-width: 100%; " alt="How to sew the sheath for a knife">
We process the contours on a grinder with a belt of 60 or 80 grit. As an alternative, you can use a grinder or a grinding machine with a flap disc. It is better to process the skin on the emery tape, since the stone is clogged with its particles and “burns”. The task is to remove all irregularities from the knife and maintain the right angle between the end and the sides of the sheath. After machining the contour, the width of the spacer is about 7 mm.

Marking seam

We make seam marking on the front side. We expose the caliper to a size of 3.5 mm, draw two lines from the tip to the mouth. The insert fastened to the rail rests against the end, and the second, mounted on the rod, is used as a scriber. The line will accurately copy the shape of the scabbard, and its quality depends on how well the butt was ground. We set the pitch of the seam on the caliper (I have 7 mm). We mark the first point for drilling at the intersection of the lines (the sharp tip of the sheath). We install one caliper insert into it, mark the next hole with the second one. Rearrange the instrument one step at a time until we reach the mouth.

To make the markup clearer and correct possible inaccuracies, it is advisable to go over it again with an awl. Determine the place where the strap will be (drawn with a pen).

Drilling holes

Pros working with leather, make holes with a specialized tool - punch.I used a desktop drilling machine (drill diameter 1.8mm).

The same operation can be done with a hand drill or with an engraving machine, but you will have to carefully follow the verticality of the spindle, otherwise the seam on the wrong side will "walk". While you are near the machine, you can make grooves for the strap and hanger. I drilled holes with a diameter of 5 mm and cut a shoemaker between them.

We refuel the strap, insert the knife and outline the fastener. First, we drill the top hole (for the head, diameter - 5 mm), then we outline the bottom hole (for the screw, 4 mm).

After installing the screw and checking the extra part of the strap is removed. To facilitate the passage of the head through the hole, we make an incision in it of a length of 3-4 mm. Note: the skin color has changed. After drilling, the billet of the sheath is processed on a sandblaster. After that, I rubbed the ends with carnauba wax and walked around the rest of the surfaces.As a result, the edges turned darker. For applying carnauba wax, a cloth wheel was used, mounted on a sharpening machine. Paraffin can be applied manually directly on the end, and the rest of the surface covered with shoe cream.

I used a saddle stitch - simple and reliable. Cut the thread from the bobbin and thread its ends into two needles. We make two seams: from the side of the butt and the cutting edge of the knife.

To fix the thread, thread it in the eyelet, pierce 3 cm from the edge and tighten. So it will not slip when broaching through the hole. With this thickness of the sheath (about 10 mm), the thread should be 6 times longer than the seam. Do not do less, otherwise it will be inconvenient to work or it may not be enough. We thread the needle into the hole at the tip of the scabbard and align the thread. To facilitate the broach, you can use pliers. Insert the needle on the front side into the next hole. We stretch the thread to the end, making sure that it does not twist. “Wrong” needle pass through the same hole towards.We perform the final tightening.

We start each stitch from the front side. We try not to pierce the thread that is already in the hole with the “counter” needle. At the end, the seam must be fastened. To do this, re-sew the last stitch in the opposite direction, print the front thread to the wrong side, cut and burn it.
