Tutorial on How to Make a Leather Sheath for the AK Bowie
(and similar large bowie knives)

Part 1 - The Main Sheath Body

Inevitably, we all come to that crossroads in life where even though something "ain't broke", we still yearn to "fix it". This is a classic example. There really is nothing wrong with the standard sheath that comes with the Himalayan Imports AK Bowie. However, since I had already put a new handle on the knife itself, why not upgrade the sheath too? A simple question - with a simple solution.

You too can "upgrade" your AK Bowie by following this Tutorial. In fact, this tutorial will help you build a "pancake-style" sheath for just about any large knife. All you need is a few supplies, a couple of simple tools and the time and inclination to get the job done.

List of Supplies needed

  • Approx. 1.5 square feet of 6-8 oz. leather, available at Tandy Leather Co. (or others).
  • Spool of Waxed Thread - preferrably dark brown
  • Contact Cement (for leather)
  • Blue Masking Tape
  • Leather finishing goods (I used wax, mink oil & edge dye)

List of Tools needed

  • Knife to cut the leather (I used an Olfa Rotary tool and an Exacto blade)
  • Ruler (I used a 12" carpenter's square)
  • Cutting board (I used an Olfa mat)
  • Pencil & Marker
  • Groover
  • Overstitcher
  • Drill press (or hand drill) and 5/64" bit (or 1/16" if you don't have it)
  • Bone folder
  • Leather needles (2)
  • Paper to make a mock-up model

It's hard to say what it would cost to do this project, because it depends largely on what tools and supplies you already have. My cost was low because I had all of it. But your cost may be high because of the number of tools you need to buy. Suffice it to say that all the supplies listed would total around $25-30, and the Tools required (assuming you only need leather-specific tools) - anywhere from $20-40.

Before starting any sheath project, I make a paper model to test out the size of the sheath, the stitching and any straps, frogs, loops, etc. I get a much better end-product that takes less time to make and gives me better quality (because I'm not second-guessing, or shooting in the dark).

The overall idea was simpler than most sheaths I've made - just a "pancake-style" sheath (vs. pouch). However, I wanted to make a snap-less keeper strap (I'm not a big fan of snaps). The challenge, then is to make a loop that will attach to the top of the of the sheath and be easy to "release" when ready.

Once I have the paper model figured out (takes a few tries usually, I cut the pieces out of leather. I like to use an Olfa Rotary cutter - they cut straight lines and do it quickly. No problem with the 8 oz. leather I'm using. Any tight curves can be trimmed up with an Exacto blade.

 

 

You can see in these pictures that I usually leave about 1/2"-3/4" around the spine, and 3/8"-1/2" around the edge - as extra room for the sheath. Since this sheath will be wet-molded, I'll need the extra space.

You can also see the extra "flap" I made at the top of the sheath. More about this later.

 

Here are the finished major pieces. The belt loop at top, followed by the "outside" piece and then the "inside" piece at bottom. I've gone ahead and marked them on the rough side since, frankly, it's very easy to forget which is which and mess up the whole thing.

 

The first thing I do is glue-up the belt loop. I didn't want to use an integral belt loop on this project because I don't like seeing the rough leather exposed. So I created a separate belt loop. In order to be able to stitch the belt loop, I need to glue-up the loop side (inside) first.

The pic on the left shows the smooth side being prepped for glue up. I use a strong Contact Cement available at Tandy's Leather. Also, the smooth side needs to be "roughed up" a little or it won't form a strong bond. I use the exacto blade for this. Contact cement works best when you goop it on thick and let it sit for 30 minutes or so. When you come back, it will look "dried out" - that's ok. Just press the two pieces together and the bond will be quite strong.

The pic on the right shows the loop being prepped to be glued back to itself.

                            

I haven't shown this step yet, but before gluing up the belt loop, it's best to go ahead and groove it. You can get an adjustable groover at Tandy's (shown in the top left of the pic). Cheap and works great.

Here you can see the flip side of the loop showing the grooves. These add a nice trim to the leather and aid in stitching as well.

Lastly, a picture showing the belt loop glued to itself and the "inside" half of the sheath.

 

Now it's time to secure the belt loop with stitches to the sheath. The best way I've found to do this is to use a 5/64" drill bit in the press and just drill the holes out. I've experimented with many other methods and this one is the quickest and most accurate I've found. I use the overstitcher tool to put small "dents" in the grooves that are all equally spaced. Then I go back over them with the drill press. A 1/16" bit is big enough, but makes double stitching a pain, so I use 5/64" instead. It works great and does not weaken the leather (nor does the grooving). If my lighting is low (or my eyes tired) I'll go over the "dents" made by the overstitcher with a marker to help me see.

 

Now it's time for stitching. I use the double-needle method. One piece of brown waxed string (heavy duty), with a needle at each end. Pick a starting point and start going around. If you're feeling lazy (which I apparently was) then just use one needle and go around and back again. Finish it up by tying a not with the two leftover strands (which should be right next to each other by the time you're finished.

Here you can see where I finished and tied a double-knot. A nice touch is to take a bone folder (white plastic in the pic) and smooth the stiches flat to the inside surface. This will cut down on wear-n-tear on the sheath and keep you knife from being marred.

 

The next step is to put glue around the edges of both sheath halves, let it sit for 30 minutes and press it together. For a regular flat-ground knife - this is where you would put the welt in. Personally, I feel it's overkill on some sheaths, makes wet-molding more difficult (functionally and aesthetically), and leaves a funny bump in the perimeter of your sheath. So I left it out. If any sheath of mine ever fails because of something like this, I will gladly restitch it. So far, so good!

In the second pic, you can see that I've cleaned up the edges at the belt grinder with a small wheel (see Shop Tour to see the KMG small wheel attachment). If you don't have a belt sander, just be a little more careful when you cut it out to have smooth, long lines. My personal preference is to just glue-up the pieces and clean up the edge afterward - I don't mess with trying to get them to match ahead of time.

Now I go back to the groover to set the stitch lines for the edges of the main sheath body. As long as you are careful at every bend/corner, you'll do good, and it will look great. Wonderful tool.
 

Back to the drill press to set the holes for stitching. As you can see, it's a great way to set a nice even row of stitching. Just go carefully until you get the hang of it.

I like to drill from the front to the back of the sheath - looks better and if I have any drill-oopsies, it's not front-and-center. No oopsies on this one.

(This can also be done with a hand drill)

 

After I've drilled all the holes, I like to go back over the groove with the bone-folder. On the left you can see me using it on its edge to realign the groove. On the right, I'm using it to smooth out the little bumps made from the drill bit entering the leather. I do this front and back, all grooves.

 

Once everything is smooth, I start stitching. Again, it's a double-needle stitch. I measure out a piece of string that is 4 times as long as the perimeter of the stitching. Waxed thread is cheap. Redoing a line of stitching because you ran out (or having to make unsightly knots) is not cheap nor easy.

I thread one needle through the first hole (start at one end or the other) and pull it until it is in the middle of the thread. Then (as shown on the right) I thread one through and pull it snug.

 

Then I put the other one through the same hole. If you have different sized needles (which I do here) then use the larger one first. Pull them both tight and start over again.

If you want to cheat (which is what I do) then take the larger needle and go ahead 10 stiches and "catch up" with the other one. The important thing to watch for, is to make sure you are pulling it snug between each threading and that the stitch lays flat.

 

I go all the way around the sheath until about 2 inches from the end. The reason for this is the special keeper loop I'm making (as seen in the pic on the right).
