南非北开普省Kathu Pan 1的4a层岩屑组合距今约50万年，是最早出现刀片技术的化石之一，也是最古老的可归因于Fauresmith工业的化石组合。对卡图盘1地层4a组合的技术分析表明，叶片是使用直接的硬锤敲击从通过向心剥落广泛制备的有组织的叶片芯中系统地移除的。有些刀刃被修成了尖头。与已发表的描述大致当代刀片组合Kapthurin形成，肯尼亚和Qesem洞穴，以色列的比较表明，不同的刀片生产策略中更新世的前半期。这种多样性最好地支持了层流技术在多个地方和时间被发明的场景。
The ∼500 thousand year old stratum 4a lithic assemblage from Kathu Pan 1, Northern Cape, South Africa, is one of the earliest occurrences of blade technology and is the oldest dated assemblage attributed to the Fauresmith industry. A technological analysis of the Kathu Pan 1 stratum 4a assemblage reveals that blades were systematically removed using direct hard hammer percussion from organized blade cores that were extensively prepared via centripetal flaking. Some of these blades were retouched into points. Comparisons with published descriptions of the roughly contemporary blade assemblages from the Kapthurin Formation, Kenya and Qesem Cave, Israel demonstrate that diverse blade production strategies were employed during the earlier half of the Middle Pleistocene. The diversity best supports a scenario in which laminar technology was invented in multiple places and times.
