“…Since costal cartilage is closely associated with the bone of the ribs and sternum, the question arises whether stabs from serrated blades implicating bone also leave striation patterns within bone. Serrated and non-serrated blade stabs to bone have been studied [9,10], but stab wall striations within bone have not been described, although similar tool marks are well-recognised surface features of the cutting, chopping and sawing of bone [5].…”

“…In this respect detailed analysis of the naked eye morphology of stab wounds may prove to be more valuable than exploring applications of modern technology such as electron microscopy and elemental analysis [9]. Since costal cartilage is closely associated with the bone of the ribs and sternum, the question arises whether stabs from serrated blades implicating bone also leave striation patterns within bone.…”

“…However, tool marks identification on bone is under researched with the majority of sharp blade trauma focused on knife [1][2][3][4] and saw tool marks [5][6]. The four studies on Samurai sword trauma derived from archaeological specimens [7][8][9][10] and only one study from a forensic context [11].…”

Samurai Sword Cut Marks on Bone: Do We Know Enough?

A samurai sword is made to cut, slice and stab, has been used to decapitate, used in war since the rise of the samurai in the twelfth century, during WWII and now used in modern day crime. It is not intended to be used to hack or chop an opponent, though may be used as such by inexperienced perpetrators. The use of different weapons in war crimes, genocide and contemporary crime has led to the imperative need of positive identification of cut marks on bone made by specific weapons and to develop standard investigation processes that may assist in the identification of a specific weapon used in such crimes, especially in the absence of eyewitness accounts. The limited numbers of studies to date have not investigated the affects of different perpetrators' experience in wielding a samurai sword, the various sharpening methods and their manifestation in the cut mark itself and the effects of weapons becoming blunt through use. Additionally, assumptions have been made that some bone types will not exhibit specific weapon traits. This paper provides a summary of research undertaken to identify cut marks on bone made by samurai swords confirming the need for further research.

“…Sometimes, in order to define the marks left by a particular instrument, i.e., in case of sharp, blunt, or gunshot wounds, it is helpful to perform an experiment using that instrument [1–9]. Although, in the case of sharp force traumas, it is possible to differentiate between injuries in bones or cartilages caused with serrated and non-serrated instruments (i.e., knives), the differentiation of the instrument in case of injuries to the skin and soft tissue is much more difficult [10, 11]. However, in some cases, conducting an experiment can make it possible to confirm or exclude the use of the examined instrument and avoid misidentification of an injury’s origin [12].…”

Striated abrasions from a knife with non-serrated blade—identification of the instrument of crime on the basis of an experiment with material evidence

et al. 2011

This paper presents an experiment with a knife seized as material evidence in a homicide case. The reason for the experiment was the necessity to determine whether the injuries of the deceased could have been inflicted with this instrument since in the course of the investigation doubt arose as to the origin of linear, parallel scratches around one of the wounds and on the abdominal integuments suggesting a serrated blade. The knife found near the crime scene had a smooth blade and small serrations only on the borderline between its blade and hilt. However, the performed experiment showed that if the knife is directed towards the integuments of the body in a special way, its serrations, even though not located on the blade itself, may leave such striated marks on the body, as those found during the autopsy, suggesting their origin from a serrated blade.
