Multi-thematic studies on asymmetrically bifacially backed knives from the Late Middle Paleolithic. Research on equifinality and permutation on Keilmesser with tranchet blow using technological, research historical and experimental approaches.

这个项目考察了旧石器时代晚期KeilMessergruppen的同名石器KeilMesser(非对称双面背刀)。重点放在具有横针-吹风修改的KeilMesser上，使用多主题方法分析其内在的技术特征。该项目通过重新评价组合、研究历史反思、考古实验和超区域对比来讨论岩石技术和时间空间问题。基于案例研究的技术数据和超区域对比考古实验。这些检验了胎体和刀具的配料、等效性(多个胎体可以用来生产同一产品)和生产阶段的排列(工作阶段的互换性)的相关性，以及形状对处理的影响。实验与案例研究集合的相关性允许演绎地扩展石块成形概念的系统和分类，并与多角度测试的概念--带转针吹气的KeilMesser相补充。博辛斯基和约里斯在制作PradnikHoront时使用了经过检查的带转针吹风的KeilMesser，这一事实证实了这一研究项目的相关性，但对这些石器进行的超区域、技术比较大多缺失。因此，本研究的目的是基于西欧和中欧地区组合的区域现象，对旧石器时代晚期以来的岩石技术的具体方面进行超区域反思，这不仅在考古学上对组合有价值，而且有助于岩石系统学的充实。

This project examines stone artifacts, which are eponymous for the Keilmessergruppen of the Late Middle Paleolithic, the Keilmesser (asymetrically bifacially backed knives).The focus is on Keilmesser with tranchet-blow modification, which are analyzed using a multi-thematic approach for their immanent technological features. This project discusses litho-technological and chrono-spatial questions via the reappraisal of assemblages, a research historical reflection, archeological experiments and supra-regional comparison.Based on technological data from case studies and supra-regional correlation archeological experiments are conducted. These examine the correlation of matrix and tool confection, equifinality (numerous matrices can be used to produce the same product) and permutation of production stages (interchangeability of working stages), as well as the influence of shape on handling.The correlation of the experiments with the case-study assemblages allows to deductively expand the systematic and classification of lithic shaping concepts and to complement it with the multi-perspectively tested concept - Keilmesser with tranchet blow.Technological features are extracted in personnel, which are experimentally tested and underpinned. The relevance of this research project is substantiated in the fact that the examined Keilmesser with tranchet blow was used by Bosinski and Jöris for the formulation of the Pradnikhorizont, but supra-regional, technological comparisons of these stone artifacts are mostly missing. Therefore, the aim is, based on regional phenomena from Western and Central European assemblages, to conduct a supra-regional reflection on specific aspects of lithic technology from the Late Middle Paleolithic, which not only archeologically values the assemblages but also contributes to the substantiation of lithic systematics.
