Short video improvised while I asked Bernard if he could knap a few nice obsidian slabs for me so I could turn them into bifaces. Extremely fragile and razor-sharp, obsidian is a superb material, but hard to spall because of its being fragile. This here bloc has many fractures which make big spalls hard to come.

Now the blade preform is finished, but there are still many imperfections on it. It will be difficult to get nice long and regular pressure flakes out of such a rough preform. This is the reason why I fully polish the preform: flake over grinding will then be much more efficient because the surfaces will be perfectly convex.

I crush small flint flakes on a big sandstone rock. Then I add water so as to obtain a ""grinding soup"" that should increase the efficiency of sandstone. The rest is just a matter of time (mostly)... and muscles ! It took 2 h30 to polish the blade (faces and bevels for pressure platforms on the sides)

With a copper-rod pressure flaker (chalcolithic period) I retouch by pressure the whole first face of the blade, to create long and parallel scars on it and serrations on the edges. I start with the point, with tiny flakes, that get longer and longer as I proceed toward the base of the blade.

The first half of face 1 is now finished, so it's time to pressure flake the opposite edge.

A few tweaks on the edges with a quartzite stone and I'm finished with this face.

Is it easier or not to use sawed slabs for making flint blades or points ? In my opinion it isn't. Working on those slabs requires greater efforts than knapping a spall. Flint loves convexity and the surfaces are here flat ! The positive point is that a flint nodule will give more preforms if sawn rather than spalled... but I still prefer knapping a spall with an antler billet.

As tough as it may be, an antler needle will not go through such a thick piece of leather, so I must make holes first. With a small flake that I retouch so it becomes sharp, it should be easier. The thread I use here is made of sinew fibers. Once the holes are made, it's heasy to sew.

The very first video recorded by Bernard and Cayoo. Once upon a time there were a cameraman who was commenting and a flintknapper who was saying harsh words.... A first levallois point is knapped off the core in one minute... not perfect though. A second attempt only creates a pseudo-point and the third try totally destroys the prepared platform. This kind a debitage is quite tricky and challenging.

One of the many method for creating a Levallois point is to drive 3 flakes off the core (one in the middle to create the hafting scar, 2 overshot flakes on the sides to create the triangular ridges), then the point itself is knocked out of the core with a single blow of a hammerstone. Because of a power outage we weren't able to complete the whole movie, but you may watch a refitting of the flakes and points...

It is necessary to carefully shape and prepare the crested blade (the first to come off a core) because of the ridges it will leaves on the core... Those ridges will serve as a guide for the next blades. The crested ridge, though wavy, has to be relatively regular and straight. The regular convexity of its outline (its profile) should also be checked in order to avoid step-fractures or overshot blades...

Once it is prepared, the crested blade is probably the easiest blade to knap. It is in itself useless and is rarely used as a tool.

It is often neglected, though rubbing the platform prior to percussion is absolutely fundamental.

There are actually 3 keys to a perfect blade debitage: convexity, bending and flaking angle...

Filmed by a class student. The main problem beginners flintknappers are confronted to in laminary work is anticipation. It is mandatory to create VOLUMES in order to knap many blades off a core. Some blades are even knapped, not for themselves, but for the negatives they leave on the core (thus creating volumes). Later on this allows you to obtain blades with desired characteristics.

Laminary work on 'livre de beurre' cores are highly tricky but it allows to create VERY long blades, like the ones used on the Charavines knifes, for example. The Bergerac flint bloc I use has many inclusions on its convex side, so I'll have to use its concave part (which is not the easiest one to work on, even if the flint is there of a much better quality).

I create an oval core with a regularly convex surface. Using the flakes negatives on the lower part of the core as platforms, I create a good convexity on the upper side. I use a punch or direct percussion. The smoother the core, the longer the blades may be. Though a bit different, this knapping technique is similar to shaping a Levallois core (using platforms under the core to create an upper convexity).

Now the core is almost ready, but I still have to create the platform: I litterally 'behead' the core, which gives an ideal angle to it, then I carefully shape my platform. I use a deer stag punch and a hammerstone... but it doesn't come as good as I hoped.

After 15 minutes of carefull shaping, the core looks perfect to me... I show every sides of the core to the camera before knapping the first blade, which breaks in 3 parts !
