Making opposed platform blade-points

This is the third and final post from my day with John Lord, and it may be the longest. The primary aim of going to see John was to get his perspective on how to make opposed platform blade-points. Karl Lee produced around 20 blade-points for my doctoral research, and whilst formally pretty similar to archaeological examples there were differences. This is the archetypal example of a blade-point from a site in Sussex called Beedings.

The main difference between Karl’s points and the archaeological examples was to do with how they were made. When a flake is removed it leaves a scar. Tracing these scars on tools can indicate the direction of impact and order of flake removal. In this way a blade-point’s production process is recorded on itself. This next photograph is the smallest complete blade-point found in Britain, from a site called Glaston in Leicestershire.

70% of Karl’s blade-points had scars running only one way. He explained that it takes time to produce a platform on a core, and once produced it makes sense to use it until you run into problems. When you run into problems flip the core over and use the second platform. Karl believed this was why there was an opposed scar pattern on some blade-points. This explanation made total sense, and reflected his primary use of one platform. However, when I was able to contrast the experimental and archaeological examples 70% of the archaeological blade-points had scars running two ways, almost the opposite proportion to Karl’s examples. Something else was happening in the past. I wanted to see how John Lord would approach and explain this process.

The answer to that question was that he saw it in almost exactly the same way as Karl. John had two goes in the morning and both times had difficulty with the flint quality. We had lunch and then he had another go. He had more success this time, but like Karl was using a single platform to generate the blades. He worked hard to produce a couple with an opposed signature but these were the exception. Over lunch we were talking about Levallois points, where the point is shaped on the core, and then simply removed and ready to be used. John suggested this same idea may be at work here, with the base of the core being worked simply to shape the points before removal. this is an intriguing idea, and the ball is firmly back in my court. I need to review the archaeological examples used within my analysis in order to see if the scar pattern pattern reflects this explanation.

I find it intriguing as well that John’s approach would be the same as Karl’s, and it made me think about the lineage of flint-knappers in this country. I know Karl has worked with John in the past and so perhaps it is not surprising that they approached the same problem in the same way. I think it would be a really nice, and enjoyable research paper to establish the lineage of British knappers, because it seems to predict particular ways of doing things. It is apparent that these ways do not necessarily correspond with how things were done in the past, and so it would seem important and useful to pick apart how and why things are done as they are in the present, almost ethnographically. This as a precursor to exploring any past production practice. These are my current thoughts. If this post is of interest to anyone then chapter three of my thesis outlines Karl’s approach in detail.

Neolithic leaf shaped arrowhead

Whilst away on holiday I paid a visit to the Whitby Museum, well worth it if you should get the chance.

Inside there is lots of treasure, and this is a photograph of a lovely Neolithic leaf shaped arrowhead found locally.

This, by contrast, is my point from today (and yesterday) made from a really thick piece of glass given to me by a friend, Stephen Poole.

It started out as an exercise in exploring the differing functions of hard and soft hammer in the process of reduction. In this respect it was successful as I now have some nice flakes for reference purposes.

However, the striking difference between the flakes produced by the different methods was also useful for me in deepening my understanding. Thinning a nodule to produce a handaxe is a process that I have observed (and filmed) a number of times. Karl Lee always emphasises the import of understanding angles. The stark contrast between these flakes is allowing something to fall into place for me (conceptually, not yet practically!) The hard hammer is perhaps more about producing angles to work with. The soft hammer more about exploiting those angles to thin the piece effectively.

I don’t like this arrowhead. It is too thick and lumpy and will probably go into the box in my back yard where my not quite resolved experiments end up. However, I have made it my point for today (made yesterday, finished today) which keeps the process, and therefore learning opportunities, going. What is intriguing for me is how the actual flakes themselves are helping me understand  the process differently. Learning from the materials seems to encourage me to think about something I already know about in a different way. This thinking through objects is obviously something we do a lot within archaeology. It will be interesting to pick apart how the objects have added to my understanding in a way that observation and explanation have not. Perhaps the theme for another post.

Karl Lee pressure flaking glass

This is a link to a short video of Karl Lee pressure flaking glass . It is of interest to me because it illustrates how he uses his knee “like a vice” to remove the flake. The large piece of glass was modern, and probably a table top. This is the end result.

Glass Kimberley Point by Karl Lee

karl point

Today we had Karl Lee for the day, demonstrating and producing various pieces for three different research projects including my own. I tasked him with producing a Kimberley Point from the second piece of modern 6mm plate glass found at Chorlton Water Park. He did a pretty good job as can be seen above. Because the glass had a hole and a bevel Karl thought it was toughened table glass which would explain why it was difficult to get the removals to travel. He did however do a better job than me, and I think shape wise his is more characteristic of what would be described as a Kimberley Point. The day was pretty successful, however for me disappointing. For various reasons I wasn’t able to capture the video footage I wanted, and I had to miss the end of Karl finishing my point and so didn’t see first hand how he serrated the edges (although I did leave the camera running and so have got it). We didn’t go through the platform preparation either and so I think a trip to see Karl is in order. We can spend a bit of time playing with stuff, rather than cramming it all into one long day.
