Research on Three Types of Blade Lock Traces Opened by Drill Hole Tools
Three types of blade locks including single-sided blade locks,double-sided blade locks,and multi-track blade locks were disassembled by drill hole tools.The formed traces of various positions of each component on the locks were analyzed,and the formation processes of the traces were also assessed.By means of comparative and inductive methods,the location,shape,and distribution of the traces on the three locks were analyzed,and the inspection points and common typical trace characteristics of using drill hole tools to open blade lock traces were summarized,which provided clues for the investigation of technical lock breaking into financial cases.
