• Results showed a wide superimposition of metrical characteristics of width and angle of lesions regardless the type of blade.
• Symmetric blades show a high C.I. between the depth of the lesion and the angle of blade in perpendicular tests.
• Symmetric blades show a high C.I. between the angle of lesion and the height of the blade in angled tests.
• For asymmetric blades a high C.I. was observed between the angle of the blade and angle and width of the lesion.
• This study suggests caution in assessing the size of weapons from the metrical measurements of lesions.
Extrapolating type of blade from a bone lesion has always been a challenge for forensic anthropologists: literature has mainly focused on the morphological characteristics of sharp force lesions, whereas scarce indications are available concerning the metrical assessment of cut marks and their correlation with the size of blade.The present study aims at verifying whether it is possible to reconstruct the metrical characteristics of the blade from the measurements taken from the lesion.Eleven blades with different thickness, height and shape were used for this study. A metallic structure was built, in order to simulate incised wounds and reiterate hits with the same energy. Perpendicular and angled tests were performed on fragments of pig femurs, in order to produce 110 lesions (10 for each blade). Depth, height and angle were measured and compared with metrical characteristics of each blade.Results showed a wide superimposition of metrical characteristics of width and angle of lesions regardless the type and the orientation of blade: for symmetric blades a high correlation index was observed between the depth of the lesion and the angle of the blade in perpendicular tests (0.89) and between the angle of lesion and the height of the blade in angled tests (−0.76); for asymmetric blades in both the tests a high correlation was observed between the angle of the blade and angle and width of the lesion (respectively 0.90 and 0.76 for perpendicular tests, and 0.80 and 0.90 for angled ones).This study provides interesting data concerning the interpretation of cutmarks on bone and suggests caution in assessing the size of weapons from the metrical measurements of lesions.
