How To Make Your Own Arrowheads ~ Small Point Pressure Flaking ~

I am pleased to make available to you another in our series of publications, a new brochure about making arrowheads: "How To Make Your Own Arrowheads ~ Small Point Pressure Flaking ~ "

This publication was produced in response to a request from several new knappers for guidance on making and thinning small size arrowheads.

So, in creating these instructional materials, while demonstrating methods of careful edge preparation and advanced pressure flaking techniques to make and thin small arrowheads, I asked my step-daughter to work with me to create a number of photographs of each step. All of this information was then used to put together this new brochure.

Here is a link to download the pdf brochure for your use: SMALL POINT PRESSURE FLAKING

This electronic publication is in an 11" x 17" format, with 10 different page layouts. You are welcome to use it as a reference and instruction aid for your personal knapping efforts.

If you want to order a hard copy of this new brochure, for $14.95 plus $1.25 first class postage, simply send me an email and I will return a Paypal request for payment to you and then prepare your copy for mailing. The email address to use is: fscottcrawford@Arrowhead-Maker.com

Thanks for your participation in flint knapping and arrowhead making activities.

Edge Preparation Gives You The Edge In Pressure Flaking

Since so many of you have requested and downloaded the "How To Make Your Own Arrowhead" instruction book recently from my web site, http://www.arrowhead-maker.com/, I thought you might enjoy this story. The other day I had one of my new arrowhead making students come by the house to pick up his Beginner's Knapping Kit. Mike lives 30 minutes away and took the opportunity to save the shipping cost.

Anyway, when he came by the house, I was working on an obsidian blade. It's made from a spall of transparent black obsidian from eastern Oregon . Originally I used the chunk of obsidian to produce a good number of the middle sized chips which are used in the Beginner's Kit for making arrowheads.

After these chips were removed, I had left what is referred to as a "core". I worked on the core a little more with my percussion tools to end up with a fairly large "pre-form" for a spear point or knife.

Then I began using pressure flaking to remove the rough parts and prepare for finishing the blade. Eventually, I had the piece worked down to the condition where I was ready to finish its form with some careful pressure flaking.

I was about half finished with the final series of pressure flakes when Mike showed up.

So, I took the opportunity to show him how the edge of the blade was set up for that finishing series. Making the edge angles correctly, grinding the edge enough to give the pressure flaking tool a good seat and grip, so that it will not slip off. Plus, retaining enough material mass at the ground edge to have sufficient strength to resist the pressure load until the force is built up enough to drive the desired flake a long way across the face of the blade.

Fortunately, I had good luck with the impromptu demonstration for Mike. The finishing of this blade went well.

So, here it is. It is what is called an Agate Basin blade. This was a Paleo-Indian weapon used for hunting large game at the end of the Ice Age; woolly mammoths, giant buffalo, etc. These were used at the same time and after the Clovis type weapons which are so famous for their uniquely thinned, fluted bases. The Agate Basin point is just not fluted, so it has the lens shaped cross section for the full length of the blade.
