How to Make a Hidden Knife
Kerchiefs have many uses in the outdoors, from bandannas to wrapping wounds to making quick sheaths for knives. (portrait in the forest image by Renata Osinska from

When spending a lot of time outdoors, sometimes it is best to keep a knife hidden in order to keep it from bumping against brush and falling or getting soaked during rain storms. While there are concealment sheaths available for purchase, this article deals with the situation when the sheath has been lost or for some other reason is not available. The technique described in this article can also be used to keep emergency backup knives secure.

  1. 1

    Wrap the knife snugly in a kerchief, tying the two loose ends together in a double knot, much like the double knot used in shoelace tying. While it does not matter how the knife is wrapped, a good way is to place the knife in the centre of the kerchief and wrap the outer portions around it.

  2. 2

    Determine the location where the knife will be hidden. Some users prefer placing it underneath their trousers, while others prefer keeping it secure underneath long sleeves. It is also possible to place it on the part of the hiking pack that rests against the hiker's body, or attaching it to an undergarment, such as a bra strap.

    A lot of sheaths can be strapped to the ankle or thigh of the leg; the same is true for the makeshift kerchief sheath. (woman pant for fitness image by Andrea Massimiani from
  3. 3

    Take two additional kerchiefs and slip one under the double knot and the other under one of the fold wraps concealing the knife. Pull these kerchiefs through enough so the wrapped knife is located in their middle sections.

  4. 4

    Place the concealed knife on the area the user wishes to conceal it, making sure the pulled through kerchiefs face the surface on which the knife will be tied. Once the wrapped knife is in a comfortable position, wrap the pulled through kerchiefs around the surface. If placed against a leg or arm, wrap the kerchiefs around the skin and double knot the ends. Make sure they are tight enough to where the knife won't slip and loose enough not to be uncomfortable. Even if the wrapped knife does slip a little, it will not be able to slide over a shoe or out from under a snug long sleeve.

Tips and warnings

  • There are two ways to tie the looped through kerchiefs. The second way is to tie one end of the top kerchief to the opposite end of the other kerchief with double knots. This creates a crisscross pattern between the two kerchiefs, and may help with slipping issues.
  • This technique is best suited for smaller knives, such as pocketknives. For larger knives it is best to wrap it with more than one kerchief or with a extra pre-made sheath so the blade does not cut through and fall out.
