How To…. Primitive Skills – Bone Knife Bark Sheath

This How To…. lays out some simple steps to make a bark sheath for a knife. I have also used this method to make a quiver for my arrows and with a sightly different method you can easily make containers.

Sweet Chestnut Bark Sheath

I took these pictures in 2009 when I was on the Woodcraft School Primitive Technology course. The sheath was made using only primitive tools as required by the course. To do this I made for myself a flint knife, flint adze, some discoidal flint knives and also used the bone bodkin that I showed you how to make in the previous post. For more modern methods I would say you could do this job with a small saw and a small knife.

I started the project by selecting a suitable Sweet Chestnut (Castanea sativa) limb from a coppice stool to take down. After checking the tops for any dead wood I started to clear away the undergrowth using some flint. Clearing the undergrowth away ensured a safe working area around the limb. I used a large sharp piece of flint for this. Also I made sure I had clear exit routes around the limb I could use when it came down.

Trimming and starting the cut

I had created for the job a Flint Adze. This is a piece of worked flint attached to a handle with rawhide. Unlike traditional tree felling where a wedge is created and then a back cut made I am made a rosette cut all around the tree using short chopping motions. You can see the rosette cut appearing in these pictures. The small branch you can see in the foreground got in my way so I cut this down.

The Rosette cut

You can see that the Adze creates tears in the wood but is very effective in cutting into it. As I got into the heartwood I had to support the limb as I did not want it to fall uncontrollably and eventually I was able to let the limb to fall under control. I did not need to back out of the coppice stool as the limb was light enough to control. Had it been any heavier, my cleared exit routes would have come into play.

Traditionally the stump would have been left like this. I however sawed the stump cleanly at the base. If a stump is cleanly cut (with a little angle) then it has less chance of getting infected and will eventually have new shoots grow out of it.

Using the Adze in a safe manner away from my body I trimmed off all the brash from the limb.

Trimming the limb

Using the flint that I had cleared the undergrowth with I scraped off all the outer bark of the limb as this is too brittle to work with. All I wanted to use was the inner bark. My friend Paul held the limb to secure it: this speeded up the process as I could use both hands.

I scored a line down the limb through the inner bark with my flint and also scored a line around the limb at the top and the bottom. Then, using a small piece of wood I’d found on the ground, I peeled away the inner bark from the limb. This was done in April so the sap was rising, making the debarking of the limb very easy.

Scraping and de-barking

The tools I used for the job:

1) Adze

2) Flint

3) Piece of wood

I cut a further piece of bark off the limb as well.

Fresh bark ready for drying

I left the bark to dry out overnight and then re-wet it the next day before cutting it into strips. If you use the bark straightaway after harvesting it, anything you weave will become loose as the bark will shrink slightly as it dries. This shrinkage does not happen again if you let it dry out first then just re-wet it to make it supple enough to work.

To cut the strips I had a flint knife prepared for this.

I cut the strips by eye only but I am sure you could rig up a worktop to cut consistently wide strips. The good strips are on the right and the offcuts on the left.

Bark strips

With practice you will be able to gauge how many strips you’ll need for your size of sheath. This was a small sheath so I estimated 6 strips.

Chosen strips

Firstly fold all your strips in half with the inner part of the bark showing as it is the smoother side.

Fold the strips in half

I have documented the first 12 steps of the weave in the next 3 pictures. Each numbered bullet point relates to a numbered picture below.

1)  Lock the right hand strip onto the top half of the left hand strip.
2) Lock the next right hand strip onto the bottom half of the left hand strip.
3) Lock the third right hand strip onto the top half of the left hand strip.
4) Lock the second left hand strip onto the top of the first right hand strip and weave through the other strips.

Weave 1

5) Lock the third left hand strip onto the bottom of the first right hand strip and weave it through the other strips. The ‘point’ of the sheath is now complete.
6) Fold back the top of the first left hand strip.
7) Fold the bottom of the first left hand strip diagonally over the other left hand strips.
8) Then flip back up the top of the first left hand strip.

Weave 2

9) Lock the next right hand strip onto the bottom half of the left hand strip.
10) Flip the whole sheath over. There should be a single strip on the right now.
11) Now fold the bottom right strip diagonally over the other right hand strips and weave it in.
12) Starting again on the left hand side keep repeating the whole process.

Weave 3

Soon your sheath will take shape.

Keep weaving

Keep going with the weave and stop when you have enough to securely hold whatever will be kept in it.

Photo 11-01-2014 23 43 54
Ready to close off

The top can seem a little bit tricky at first but all you need to do is turn the ends back on themselves and weave them into the sheath. Just tuck each end in as neatly as you can: it’s tricky as each end will be different, you might need to experiment.

Photo 11-01-2014 23 44 07
Closing off

When you have closed the top off, trim all the ends so that you cannot see where the weave ends.

Photo 11-01-2014 23 44 21
Trimming the excess

All the ends were trimmed so that the ends were hidden by the weave. The sheath is ready for a dangler strap now.

Ready for a loop attachment

I used some raw hide I had left over from making a bag. I wet it to make it more pliable and then rolled it in my hand.

Re-soaked rawhide

The bodkin I had made earlier came in handy here to make a gap in the weave. I then used a small stick to push the rawhide into the gap made by the bodkin.

Attach it as you like and it is ready. I think I used a simple Larks Foot knot here.

This sheath completed my primitive belt order (the smallest one on the right).

My Primitive belt order

This type of weaving can make some very useful items. I have been using the quiver on a regular basis since 2008 and it shows no sign of wear and tear.

How To…. Primitive Skills – Bone Knife/Bodkin

Primitive Bone Knife

During the summer of 2009 I completed the  Woodcraft School Primitive Technology course. I do not know if John Rhyder still runs this course but he still does a lot of excellent craft courses.

I originally wrote this How To…. for Fenlander and his Natural Lore blog back in September of 2009. It is a subject I love so thought it would be good to include in my How To…. section as well. I apologise for the quality of some of the pictures, I think the light was poor at the time and my fingers were quite slippery from the marrow.

The course required that at least one our craft items had to be made using only primitive tools and techniques.

I decided to make myself a bone knife and a bark sheath for it. The knife I made from a Lamb’s thigh bone and the sheath was made from Sweet Chestnut (Castanea sativa) inner bark. The How To…. on making the sheath can be found here – Primitive Skills – Bone Knife Bark Sheath.

This post concentrates on the knife only. I have put another link yo the bark sheath at the end.

The techniques I used were from what I had researched at the time and I am sure there are many other methods to do this.

As a word of warning please do have a First Aid Kit on standby as the flint is very sharp and thoroughly wash your hands after wards.

Bone Utility Knife and Sheath

I wanted to be able to use the knife as an Awl for working hides, as a Bodkin for when weaving and as a general knife for cutting cordage and meat.

This post will concentrate on how the knife was made. The next post will be about the sheath.

The bone I used was a thigh bone known as the Shank. Hence the names ‘Lamb Shank’ as a cut of meat and the word ‘Shank’ as a primitive knife.

Fresh Bone and Flint

As I was using primitive tools and techniques only I scraped all the fat and flesh off with a piece of flint.

Other students tried burning the fat and flesh off but the made the bone brittle so it easily shattered. It is slippery work that requires a lot of patience. One slip and the flint will cut you as cleanly as any sharp knife.

20140104-153725.jpg
Slippery Work

After an hours work I had the bone cleaned up.

20140104-153740.jpg
Ready for Carving

I decided that one knuckle would make a good handle but the other had to be removed.

I scored a line around the whole bone near the knuckle I wanted removed. Apologies for the slightly out of focus picture. The score line was about a couple of millimetres deep.

20140104-153753.jpg
Removing a Knuckle

After scoring the line John Rhyder (course instructor) showed me how to scorch the line to make it a little brittle in that area.

Scorching the Bone

A close up.

Scorch line

Once the line was scorched all the way around a little gentle tapping was all that was needed.

A crack soon appeared.

Cracked Bone

To finally remove the knuckle I carried on scraping with the flint.

20140104-153905.jpg
Removed Knuckle

Once the knuckle was removed then I decided on the shape of my knife point. I did this by gently scraping with the flint on the bone to define my knife shape.

20140104-153918.jpg
Flint Score Lines

Then making sure that the bone was on a stable surface and held in a secure grip the tedious scraping began. The carving out of the knife shape took a number of hours.

Eventually I was able to prise a section of bone out.

20140104-154001.jpg
Removal of Bone

I went through two pieces of flint carving the bone out.

Eventually the general shape of the knife was produced.

And the other side.

Basic Shape – Back

A messy but necessary job is to remove the remaining marrow. I just used a small stick for this.

To give the knife a basic edge I used a piece of sandstone.

Any rough edges I tidied up with flint.

Final Touches with Flint

Below you can see the side profile of the knife. This curve is useful as a Bodkin in basket weaving. In the next post you will see that this was the knifes first job.

Here the knife is sitting on the inner bark I used to make the sheath out of.

Ready for a Sheath

Like any knife it needs a sheath. I did produce one using primitive methods and documented all the steps.

The Sheath How To…. is next

This whole process took a whole afternoon for me but I did find it very relaxing taking my time and really thinking about each step.

Afterwards I left the knife hanging for a few months in my garage to air dry and keep it away from any inquisitive rodents.
