Assuming they know what will work, I fashioned a handle from some ash I have and proportioned it so that I achieved the "right angle" geometry suggested by bowl maker David Fisher.

That style is used by other blacksmiths, including some popular ones from Europe. On the small adze from Mike I copied the style I have seen on Jason Lonan's adze. I wanted something closer to 20-22 ounces, so I removed about 7/16" from the length of the throat at the same time I cut the handle off so it could be removed. Given all of that, I carefully ground the outside bevel to produce a nice rolling bevel, then worked it to a nice, clean edge.īut, the adze had just a bit more weight/mass than I was hoping for. Pete Galbert takes a series of chops with the grain and then scoops them across the grain. It seems the proper technique is kind of a circular movement, at least to clean the surface. Again, I have never used an adze - just going from everything I have read and watched. The outside had a decently formed bevel and the edge wasn't too bad, but I wanted a more "rolling" bevel that I felt would work better and still give me the lever effect so I could pull out of a cut. It was a fairly quick job getting it to a polished surface. The inside of the blade was cleanly ground with no bevel. But, upon receipt I was presently surprised. I also knew the geometry of the handle wasn't right. that I could find and expected it to be pretty rough when received. I own a couple sets of their chisels and like the metal. Not knowing if I can even develop the skill set to use one effectively, I just couldn't justify that cost. Most all of the current hand forged adzes run in the $300-350 range. It was a really neat tool, and handled well, but I felt it just didn't have enough mass to do some of the deep seat hollowing I do on the Windsor chairs I am building. Some of you may have seen that post in the Classified forum. This would change our understanding of stone tool use by Ice Age humans, and how such technology was spread into different environments.I previously purchased from Mike Henderson a small hand forged adze head and fashioned a handle for it. The team believes that if similar traces are found on the edges of real artifacts from Marine Isotope Stage 3 sites, this would mean that humans had honed woodworking technology from significantly earlier times than is currently believed. While fractures alone cannot tell us what they were used for, they found that combining both macroscopic and microscopic evidence can help us make reliable conclusions about whether the edges were used to fell trees. They found that impacts like those required for cutting down trees leave distinctive, macroscopic fractures on the stone friction at the micron-scale between the stone edge and wood also forms microscopic traces that may be used for diagnosis. Edges were then examined in depth for both macroscopic and microscopic traces of their history. The team then got to work using the tools for 15 different activities, including tree-felling, hide-processing, and butchering, as well as "non-use" events like carrying them around and trampling them. Though hafts have not been recovered from Japanese sites of the period, they adopted methods from Irian Jaya to attach a handle to the stone edges to create adzes, axes, and chisels. The findings are published in the Journal of Archaeological Science.Įdges were crafted and polished using knapping and grinding techniques which would have been available at the time. They took a hands-on approach, and crafted replicas of tools that might have been used in the Early Upper Paleolithic age (about 38,000–30,000 years ago). To address this, a team led by Assistant Professor Akira Iwase from Tokyo Metropolitan University has tried to establish what kinds of traces might be left on ground stone edges when they are used for different activities.

The important question becomes what they were used for at such an early stage.

In sites around Australia and Japan, many ground edge artifacts from Marine Isotope Stage 3 (about 60,000–30,000 years ago) have been recovered. This is underscored by the availability of tools that let people craft more and more complex wooden instruments, particularly polished stone axes.īut while developed wood-processing technology is generally believed to be associated with a way of life seen in the Neolithic age of the Holocene, starting approximately 10,000 years ago, ground stone axes have been found from periods significantly before this. While Paleolithic (early Stone Age) artifacts point to the use of wood for simple tools such as spears or throwing sticks, later Mesolithic and Neolithic artifacts reflect far more sophisticated uses, for building houses, canoes, bows, and wells. For prehistoric humans, improvements in woodworking technology were revolutionary.
