Product Overview

The Prying & Levering Mark Sample Maker — Precision Multi-Dimensional Adjustment, Controlled Pressure Loading, Standardized Parameter Reproduction, Professional System for Tool Mark Judicial Forensic Sample Preparation & Identification (also referred to as the Prying & Levering Mark Sample Maker or Tool Mark Sample Preparation Device) is a professional sample preparation device specifically designed to address the core challenge in tool mark judicial forensic identification. It constitutes a core sample preparation device in the fields of criminal technical tool mark examination, judicial forensic trace evidence comparison, and the standardized construction of forensic science laboratories. This product is deeply customized for using a suspected tool to precisely and repeatably produce test samples that are highly consistent in morphology with the scene marks during tool mark comparison and identification. Through its precise mechanical structure and scientific design, it can accurately simulate and fix the relative positional relationship between the tool and the object material at various angles, pressures, contact point positions, and penetration depths, thereby producing high-quality prying and levering mark samples in a standardized and systematic manner. The system perfectly adapts to various professional scenarios, including the sample preparation and identification of prying marks in burglary cases, the comparison and examination of tool marks in sabotage cases, the teaching and research of tool mark examination in universities and scientific research institutions, and the analysis of tool-related damage in specialized industry quality inspection and accident investigation. Its core value lies in transforming the uncontrollable variables in traditional manual tool mark sample production—the contact angle between the tool and the object, the magnitude and direction of the applied force, the mode of action, and the contact position—into quantifiable, adjustable, fixable, and reproducible experimental parameters. This fundamentally resolves the long-standing industry pain points where tool mark identification has relied heavily on the operator's individual experience and feel, where sample preparation consistency is poor, and where the scientific objectivity of the expert conclusion is difficult to guarantee. It provides trace evidence examiners with "precision multi-dimensional adjustment and locking, controlled pressure loading and reproduction, standardized procedure and normative preparation, and fully recorded and traceable parameters" professional-grade sample preparation capability. It is the critical core piece of criminal technical equipment that connects the suspected tool with the scene evidence and supports the scientific expert conclusion in tool mark identification.

Technical Principle

This device operates on the combined principles of precision mechanical positioning and quantitative mechanical loading. At the spatial positioning level, the system provides a multi-degree-of-freedom precision adjustment mechanism—including independent movement axes for angle adjustment, height adjustment, horizontal displacement adjustment, and tool clamping angle adjustment. Based on the formation conditions derived from the analysis of the scene mark, the operator can precisely set the three-dimensional spatial angle, contact point position, and penetration depth of the suspected tool relative to the simulated object (sample material). All parameters can then be instantly locked in place via the independent locking mechanism on each axis. This multi-dimensional precise positioning capability ensures that the same tool, under the same parameter settings, can repeatedly produce a series of marks with highly consistent morphology on different sample materials.

At the mechanical loading level, the system employs a mechanical or hydraulic controlled pressure loading mechanism capable of applying and maintaining a constant, quantifiable pressure to simulate the force exerted during the criminal act. The pressure value can be read and recorded in real time via a force sensor or scale, ensuring that the magnitude and direction of the force exerted by the tool on the object are consistent for each sample preparation. This quantitative pressure loading mechanism fundamentally changes the operational mode of traditional manual prying, which relied entirely on the operator's personal feel and experience—the settable, reproducible, and recordable nature of the pressure parameters transforms sample production from an empirically-driven manual skill into a parameter-controlled, standardized scientific experiment. At the mode of action simulation level, the system can systematically simulate various criminal techniques such as gap-widening, prying, and clamping, covering the formation conditions of the vast majority of scene prying marks.

Core Functions and Compliance Operational Value

Precision Multi-Dimensional Adjustment and Full Parameter Locking, Enabling Precise Reproduction of the Spatial Positional Relationship Between the Tool and the Object and Standardized Batch Preparation
The device provides a multi-degree-of-freedom precision adjustment mechanism. Based on the microscopic analysis results of the scene mark, the operator can precisely set the three-dimensional spatial angle, contact point position, and penetration depth of the suspected tool relative to the sample material, and lock all parameters in place using the independent locking mechanisms on each axis. After completing a set of parameter settings, the same tool can be used repeatedly under the same parameters to produce a series of test marks with highly consistent morphology—including repeated samples at different locations on the same material and comparative samples on different materials. This precise reproduction and batch preparation capability ensures that the forensic examiner, when performing line-matching comparisons under a comparison microscope, has a sufficient number of morphologically consistent samples for a comprehensive analysis of the reproducibility and individual specificity of the tool's characteristics. This provides ample sample data support for the identification conclusion. The operational procedure and sample preparation records fully comply with the requirements of tool mark examination technical standards that sample production must be standardized and repeatable.

Controlled Pressure Loading and Quantitative Mechanical Recording, Transforming Experiential Manual Operations into a Quantifiable Standardized Scientific Experiment
The system employs a mechanical or hydraulic controlled pressure loading mechanism capable of applying and maintaining a constant, quantifiable pressure, with the pressure value readable and recordable in real time. This quantitative pressure loading mechanism fundamentally changes the operational mode of traditional manual prying, which relied entirely on the operator's feel and experience—the pressure parameter becomes a settable, reproducible, and recordable experimental variable. During identification, the forensic examiner can estimate the magnitude of the force applied during the crime based on the depth and degree of deformation of the scene mark. After setting the corresponding pressure parameters on the device, a series of samples are produced. By comparing the degree of match between the morphology of the marks under different pressures, it is possible not only to identify the type and individual tool but also to assist in inferring the method and magnitude of the force applied during the crime, providing a multi-dimensional scientific basis for case reconstruction. All parameter records and their correspondence with the samples are incorporated into the forensic case file, providing complete and traceable data for the judicial review of the scientific validity of the sample preparation method during court cross-examination.

Simulation of Multiple Modes of Action and Adaptation to Multiple Materials, Covering the Full Spectrum of Sample Preparation Needs from Gap-Widening and Prying to Clamping
The system can systematically simulate various criminal techniques such as gap-widening, prying, and clamping. By changing to different forms of clamping fixtures or adjusting the clamping angle and feed direction of the tool, it flexibly adapts to different types of tools (such as screwdrivers, crowbars, pliers, wrenches, etc.) and different modes of action. The sample material can be flexibly selected to match the actual material of the scene evidence—such as aluminum alloy profiles, copper lock bodies, steel door frames, wooden furniture, etc.—ensuring that the sample and the scene mark are comparable in terms of their material substrate, thereby preventing deviations in mark morphology caused by differences in material hardness from affecting the accuracy of the comparison conclusion.

Compliant Application Scenarios

Standardized Sample Preparation and Identification Scenario for Prying Marks in Burglary Cases
In cases such as residential burglaries and safe thefts, the trace evidence examiner mounts the suspected tool seized from the suspect onto this sample maker. Based on the microscopic analysis results of the prying marks left on the scene's security door frame, safe panel, or window frame, the examiner precisely sets the tool angle, contact point position, and pressure parameters. A series of prying mark samples are then produced on a sample material of the same composition as the scene object. Subsequently, the scene marks and the series of samples are compared line by line under a comparison microscope to identify points of correspondence and difference. An expert opinion on tool mark identification is then issued. The complete parameter records for sample preparation serve as a technical appendix to the expert report, providing complete experimental data support for the scientific reliability of the identification conclusion. The operational procedure fully complies with the requirements of tool mark examination technical standards.

Comparative Examination of Tool Marks and Damage Mode Analysis Scenario in Sabotage Cases
In cases involving the intentional destruction of property or the sabotage of production and operations, the forensic examiner uses this device to conduct simulation experiments on the involved tool using multiple modes of action (such as shearing, prying, and striking). Corresponding mark samples are produced and compared with the marks on the damaged objects at the scene. This allows for a comprehensive assessment of the relevance of the tool to the scene marks and the method of damage, providing a scientific basis for case qualification.

Teaching, Research, and Standard Research Scenario for Tool Mark Examination in Universities and Scientific Research Institutions
In police academies and criminal technical science research institutions, this device is used for standardized teaching of tool mark examination—students produce a series of samples by setting different parameters, intuitively understanding the influence of factors such as angle, pressure, and material on mark morphology. In scientific research projects, researchers use this device to conduct quantitative research on the formation mechanisms of tool marks and to develop examination method standards.

Core Technical Parameters

In terms of functional characteristics, the device provides a multi-degree-of-freedom precision adjustment mechanism, supporting the precise setting and locking of the tool's three-dimensional spatial angle, contact point position, and penetration depth. It employs a mechanical or hydraulic controlled pressure loading mechanism capable of applying and maintaining a constant, quantifiable pressure. It supports the simulation of multiple modes of action, including gap-widening, prying, and clamping. It is compatible with sample materials of various types, which can be flexibly selected according to the material of the scene evidence. The sample preparation process enables standardized parameter recording, with parameters such as pressure, angle, and position being settable, reproducible, and traceable. In terms of application positioning, it is specifically designed for the standardized preparation of test samples from suspected tools in tool mark judicial forensic identification, providing a scientifically controlled sample foundation for line-matching comparisons in tool mark identification.

Compliant Field Application Cases

When accepting a tool mark identification case for a series of safe burglaries, a municipal criminal technical science research institute needed to perform an identification comparison on multiple crowbars seized from the suspects. The forensic examiner mounted each suspected crowbar onto this Prying & Levering Mark Sample Maker one by one. Based on the microscopic analysis results of the prying marks on the safe door panels at the scene, the examiner precisely set the intrusion angle, contact point position, and pressure parameters between the crowbar and the aluminum alloy sample material. After locking all parameters, the examiner produced several prying mark samples with consistent morphology for each suspected crowbar. Subsequently, the marks collected from the scene and each sample were compared line by line for their striation characteristics under a comparison microscope. Upon comparison, the sample marks from one crowbar were highly consistent with the scene marks in terms of striation flow direction, spacing, and individual characteristics, while the sample marks from the other two crowbars showed significant differences from the scene marks. Based on this, the examiner issued an expert opinion identifying one crowbar as the crime tool and excluding the relevance of the other two. All sample preparation parameter records and comparison images were submitted to the court as technical appendices to the expert report. During court cross-examination, the expert witness explained the scientific method and parameter control process of sample preparation in court, and the court admitted the expert conclusion. In this case, the sample maker ensured the scientific reliability of the comparison samples through standardized parameter reproduction, providing solid technical assurance for the objectivity of the identification conclusion.
