A cut above the rest

Knife ergonomics lies in the blade, not the handle ...

"In this era of stun guns, 2000lb bombs, and too-advanced-to-be-tested strategic missile defence systems, few individuals understand the effect of knife-handle shape on stabbing performance. Ian Horsfall and his colleagues are among the proud, happy band of brothers and sisters. Their new report, The Effect of Knife-Handle Shape on Stabbing Performance, makes it easy for all of us to share in this knowledge. Their study is published in the journal Applied Ergonomics.

The team is based at the Royal Military College of Science, Cranfield University, in Swindon. The title of the report is a measure of the scientists' modesty: for they studied not just the knife-handle's shape, but also its size.

"The bottom line," Horsfall says, "is that stabbing performance is almost wholly dependent on the person holding the knife, and is not a function of the knife handle." He emphasises also that "this paper does not in any way illustrate how to stab people". The thrust of the research is how to protect people against stab wounds from a knife, and, especially, how to design police body armour."   continued ...   (Via EducationGuardian)
