A functional replica of a knife from the Neolithic period of Lake Contance, Germany. It is fully usable and has no damage or cracks. The second and last picture above show the original artifact, from the underwater archaeological site of Wangen-Hinterhorn under the shallow shore section of Lake Constance, which borders Germany, Austria, and Switzerland. It dates to the Horgen Culture(around 5,000 years ago), when people were making shore villages called pile dwellings. This style of knife is called a "fist knife" and our testing here shows that it was suited for sawing motions, such as cutting plant fiber and small wood saplings. This would have aided in preparing materials for basketry, traps, and smaller tools and weapons. The flint biface within was made to 7.3 cm, and it has been resharpened for further use.  It was set into the handle in the manner of the original artifact, with natural pitch as adhesive and gap filler. The handle was made in Laurel wood, which was chosen as it is a "lakeside" wood here, in the theme of the original.
