How to Make a Knife Sheath Out of Plastic-Easy DIY!


Want to take your knife on your next hike but don’t have a suitable knife sheath? Here’s how to make a plastic knife sheath out of plastic to keep you and your knife safe during your journey.

Knife sheaths are way more remarkable than the typical usage for plastic canvas, manufacturing facial tissue box covers. Wal-Mart has a wide selection of these supplies.

A sheath for any knife can be easily made from plastic canvas and strings. We’ll demonstrate how to build one here today. No specialized tools or expertise are needed for this process, other than when dealing with leather. All you have to do is know how to sew, and you are good to go!

Simple and Easy Method to Make a Knife Sheath Out of Plastic

What is a Knife Sheath and What Does it Do?

A sheath’s purpose is to safeguard the weapon and its owner when the knife is not used. The sheath’s loop can be used to hang a knife on a belt. Each knife model has a sheath explicitly made for it. The small decorations of a sheath are frequently ornamental, but they also serve a practical purpose. Many sheaths, for example, have a triangular piece of leather at the tip to minimize the jarring backward and forward movements of a sheath hanging on a waistband when walking.

How to Make a Knife Sheath out of Plastic – A Step-by-Step Guideline

This process does not necessitate the use of any particular equipment or abilities, such as those required to work with leather. All you need is the ability to sew.


  • A knife that requires a sheath.
  • Scissors
  • A Sharpie pen in a bright color that will stand out.
  • A canvas made of plastic.
  • Canvas needles made of plastic
  • Make a thread or string.

Take Exact Measurement and Make Cut

Find the knife’s widest point and leave three open holes on either side of it. We’ll sew the case in the central area to protect the string from injury, exposing one accessible spot on each end. All three strips should come from a single piece of plastic canvas.

Choose a section and trace it with the knife blade. To create room for the edge, carefully cut away the middle. Trim the top of the blade after it has been fitted to ensure its proper length.

Get Rid of the Rough Edges

It’s essential to remove any rough edges that can get in the way of the blade’s path. Use your scissors to replicate the lines on the plastic canvas closely.


One side should be aligned with the internal section. Align the knife blade to the handle once again.

Start sewing your first stitch by passing your needle through the extended outside section and then into a smaller, knife-cut area. It’s best to start in the middle of the case, one open square away from the edge. Tighten the knot on the underside of the case as much as possible. This will hold the front and rear together.

You’ll be using this remaining canvas piece to make the sheath’s front panel. There is a good chance it will have to be cut down to fit the inner section. Before cutting, re-test the knife blade’s fit. Starting in the middle of one side, sew from one end to another, leaving a square open at all times on the edge of each segment.

Then sew up the side, leaving an open square at the very edge to finish. Stop when you’ve nearly reached the height and prepare to move on to the following stage: construct the belt loop.


It’s easy to make a belt loop with the case’s long back strip by folding it in half. Secure the slit used to enter the knife but do not cover it. Make sure the belt loop is attached to the rear portion.

The belt loop should be integrated into the lateral sewing up until there is one last uncovered opening from the bottom. Begin stitching in the direction of the knife sheath’s center. Make sure the belt loop is only stitched to the rear side. Be cautious not to close the knife slit with your stitching. Take your time to fasten the strap buckle to the backside completely.

Once you’ve stitched to the far side, re-incorporate the outside edges, ensuring one uncovered square stays on the back edge. Make sure to keep stitching all the way down the other side and back towards the center point where you began.


This is the most challenging part of sewing, and it takes a lot of time. If you have finished sewing the entire case together tightly, it is ready to tie off the thread and finish. We’ll try to describe the procedure to those who didn’t learn to sew from their grandmothers. Do not pull the stitch tight as you bring it through. Return the needle to the opposite direction and loop the loose string through it several times before pulling it tight.

Put your knife in its beautiful sheath and take a moment to appreciate yourself.
