Antler Flaker Update

John — Thu, 25 Feb 2010 16:38:17 +0000

Okay, I said that I was going to make a projectile point of some kind with my new antler-tipped pressure flaker and then post the results. I made this little arrowhead last week but haven’t gotten around to posting about it until today. This is a small little ‘bird point’ that I made from a waste flake, so it is not huge. I intentionally decided to experiment with something small and if the flake tool worked out well, then I’d try it again on some larger material. And it is a good thing I started this way because it quickly became apparent that the mass of the small piece of antler I used for this tool was inadequate for larger flake removal applications. In addition, I had to cut my piece of antler shorter than I wanted because of a bend that I couldn’t get out. Ideally, I would have liked a longer piece for a more secure haft and added leverage that I couldn’t conveniently achieve with the shorter handle.

When using my new flaker, I was afraid to apply too much pressure on some of the larger platforms for fear of breaking the antler. In the beginning, I had a difficult time getting the antler to grip the platform; the smooth surface of the antler caused it to slip off before removing a flake. But after a little tinkering, I was actually able to make it bite pretty well. In fact, because of the antler is softer than the copper, it did an excellent job of gripping the platform’s edge if applied at just the right angle. This surely contributes to accelerated wear and subsequent resharpening, but when working with antler that is to be expected anyway. I can’t really give a fair or complete assessment of antler since my flaking tool is too small for thorough testing. But I do have some larger pieces of antler lying around and I want to make a new one similar in size and form to an Ishi Stick. The new one I plan to make will be larger and should be capable of removing larger flakes. When it is done, I’ll be sure to update. Until then I’ll go back to using copper and may reshape the antler flaker for use as a notching tool.

Antler Pressure Flaker

I’ve been using a copper tipped pressure flaking tool ever since I started flint knapping. But I’ve always wanted to try using antler. I suspect that most people who flint knap have picked up an antler tine at one time or another and tried chipping with it with mixed results and opinions. For myself, I never enjoyed the feel of an antler tine. It was always uncomfortable – either it was not long enough or its curvature felt awkward in my hand or the fat, blunt tip was just different from what I was used to. I assume that this is probably why 99 percent of the knappers I know use copper.

Like most flint knappers, the occasion often arises when we are either working in the public’s eye or we are showing friends how this was done in the past. When I am observed working with copper, people invariably ask me what was originally used. For this reason, I always have an antler tine in my knapping kit to show and use as an example. I will remove a few flakes from the piece I am working on, then put it away and immediately go back to the copper flaker. But I’ve always wanted to have something more functional that I could be comfortable with, and not just use for the purpose of demonstration. In addition, I use a moose antler billet exclusively during the early reduction stages (with the exception of hammer stones) so using an antler tipped pressure flaker would be more satisfying and would compliment the traditional nature of the rest of my kit. I am also very curious about the use of antler and want to experiment with it and possibly abandon copper all together (sometime in the future perhaps). So, when I came across the article about Making a Reduced Antler Flaker by Steven Edholm in Primitive Technology, I had to make one for myself and try it out. Below is the process I followed as outlined in the article:

First the antler should be soaked for a few days to soften up the material. I used the sister antler tine from last weeks post. After soaking, you can then engrave a channel down the length of both sides of the antler tine using chert flakes from your debitage bucket. These sharp pieces of stone are referred to as burins in the literature and in archeological circles. In the past, I’ve used this technique to split bone and have always gone too shallow. So, this time I wanted to make sure I did a good job, but I probably went deeper than necessary. You just need to reach the pithy core of the antler.

These are the waste flakes I used:

And this is the groove they produced in the antler:

The next step was to split the antler in half by inserting something flat and rigid through the pithy center of the antler to start separating the two halves:

Now that it is split, some additional shaping will be necessary. In my case, the tips were too narrow to support the amount of pressure that will eventually be applied during the flaking process. And the pithy center needs to be reduced to leave the inner half flat for hafting. At this stage, the antler tine is still curvy and wavy and will need to be straightened. The straightening is accomplished simply by binding the antler tightly to a straight stick and allowing it to dry. When the antler is wet, it is flexible enough that it will conform to the shape of the stick. When it is dry, it will be as hard as…well, as hard as antler.

I used some braintan buckskin to make lacing for the hafting process. I just created a flat surface on the edge of a stick for a handle and bound it all together.

Now, I’ve only used this tool a little bit to test it out. It is definitely more comfortable to use than a simple antler tine and it does do the job it is supposed to. I will confess, however, that the tine is too thin for the handle which causes it to move around a bit while I work. I believe this can be remedied by hafting it to a handle that is similar in width as the antler. As it is now, there is space on either side of the antler created by the wider handle. The result is no lateral contact of the leather to the antler.

I plan to do some knapping this weekend and hope to produce a point with it. I’ll post my thoughts on performance and pictures of the point.

Knapped Novaculite Knife

I made a little blade from a piece of novaculite and wasn’t sure exactly what to do with it. I ended up hafting it onto a piece of antler tine that I had laying around. I’ve made similar knives like this in the past as gifts for friends and think of them more as ornamental then functional. Normally I use 5-minute epoxy mixed with a little India ink to fasten the blade to the handle. The ink gives the epoxy a rich dark color to represent the classic pine pitch/charcoal mixture often used for primitive hafting. However, since I wasn’t giving this one away, I decided to actually use pitch for the primary hafting agent to see how it would bind. When I make these as gifts, I use masking tape to cover any part of the stone and handle that I don’t want to get stained with the ink/epoxy mixture. With this knife, I got lazy and didn’t use tape and made a mess on the upper trailing edge of the knife blade. It probably wouldn’t have been so noticeable if I wasn’t using a white stone. I wanted to make sure everything would hold together well, so as an added precaution, I used more pitch than was probably necessary resulting in a sloppy looking haft. Anyway, the novaculite blade itself is a little bulky for the thin antler handle and would have probably been better suited on the end of a spear insert or something similar. The nice thing about using the pine pitch instead of the epoxy is that if I decide I want to put the stone point onto a spear head at a later date, I can always heat up the pitch so the point loosens. I can then remove it and use it elsewhere.
