Here I will try to explain how I make a pouch sheath.I am using 7-8 oz. vegetable tanned leather.This piece wasnt the best but it works.
There are allot of pictures here so please be patient if the page is slow to load.
First you need the knife and some leather.
Now you trace around the knife and roll it over,keeping it in line with the line you just drew and trace around this side of the knife.
Now draw a line 1/4 inch around the traced shape,You can alter the outside shape if you want as I have done here.
Now cut arond the line on one side and check for fit then cut the other side of the sheath and check the fit again,Adjust if necessary.
using the straight gouge now gouge out some lines in the center of the sheath from the guard down.This is so the leather will fold and lay flatter around the blade.
Now cut a 1/4 inch wide strip of leather that is long enough to follow one side of the sheath from top to bottom.Then cut notch's in the leather so it will bend at the curves.
Using contact cement or any leather glue,glue the welt in place on the one side.
Make the belt loop at this time.For this sheath the piece is 3/4 inch wide (but you can make it whatever size that you want as long as it stay's inside the welt and back bend of the sheath).I make it long enough to stitch 1 inch on the tp and fold it over and let a 2 inch belt through the loop and still stitch 1 inch at the bottom.
Glue the top section down.So the ruff side will be on the inside of the loop
Mark where you want to put the stitching.o put the holes in the leather I have taken a small nail an cut the head off and then with a file and the nail chucked up in the drill press I sharpened a point on it.
With the drill press turned on and the leather on a clean piece of wood,just drill through the leather were you want the holes punched for the stitch's
on the inside of the sheth cut a groove with the gouge in line with the holes you just made.This lets the stitch's set below the leather line and reduces the risk of the knife cutting the stitch's
Now stitch with one piece of thread ( I use artificial sinew ) and 2 needles,one at each end.now stitch by putting one needle through then the other back through the same hole and pull the thread tight.keep repeating this step all the way around the holes.
When you are at the end just start backing up a couple of stitch's and stopping with both ends on the inside of the sheath.Pull them tight and then cut them about 1/8 inch long.Now to finish the thread off just melt the ends with a lighter and push them down into the hole while the are still melted.
mark and glue down the other end of the belt loop.
Mark where you want you stitching to go
With the straight gouge follow this line
Mark for your holes evenly.I use a pattern tracer from the fabric store with every other tooth removed for my spacing.
go back to the drill press and nail to put in the holes.then gouge the inside of the sheath,and then stitch it .
Glue the other side down now and then smooth the edges up,I do this on the grinder with a 150 grit belt.
If you have a edgeing tool use it now if not just smooth over the edges on the grinder,Both ways look fine and finish easily.
Using the adjustable gouge now.Set it so it is in the center of the welt and then gouge a line the length of the sheath.Start at the bottom at a point that is just inside the edge and stop at the top just before you go off the sheath.
Put in the holes on the drill press with the nail in it. then stitch it up and finish the stitch's the same way you did inside but do it on the back of the sheath.
With the knife in the sheath I put a light wetting of acetone on the leather and form the shape that I want.This dries really quick and doesnt hurt the leather.
Now I dip my sheats in a hot bath.The mixture is bees wax or you can use parafin wax (2 blocks) and Mink oil ( 1 can of the waxy kind) you can use a small bottle of the oil itself if you want.I dip my sheaths 2 times while the mixture is hot enough to almost be smoking.I just set my crock pot on the highest setting for a couple of hours before I want to dip a sheath.
After the sheath has cooled down ( I put mine in the refridgerator for a few minutes) I burnish the edges with a polished brass rod,Then I buff the rest of the sheath with a wash cloth then a soft cloth to polish it up if a high shine is wanted.
This makes the sheath water proof and doesnt let the leather rust a carbon steel bladeYou still shouldn't store the knife in the sheath for long perioeds of time as you can still have moisture get trapped in the sheath and that is not good for the knife.
