AI Thread Summary
The discussion focuses on the analysis of knife wounds, specifically comparing single-edged and double-edged knife injuries. Participants clarify that the pointed end of a wound can be attributed to either the blade tip or the sharp cutting edge (blade belly) of a single-edged knife. There is an emphasis on the importance of examining the depth and length of the wound to determine its characteristics, such as whether it is a stabbing, slashing, or incised wound. One contributor notes that the wound, despite appearing double-edged, was created by a single-edged knife, suggesting that the edges may appear less distinct due to skin stretching. The conversation highlights the complexities involved in forensic analysis of knife wounds and the implications for legal investigations.

Hello,

Here is single edged knife.

Consider
spine= blunt end
blade belly = sharp cutting edge

Here is the wound

Now the really pointed end at the left side of the wound, is it created by blade tip or the blade belly (sharp cutting edge). This might be obvious but I'm bit confused at how this wound is created, when I look at double edged wounds. Thanks :smile:

Double edged left, single edged right.

Is this for forensics analysis of knife wounds?
Your motive might be questioned if there is any legalities involved.

A knife can be used to stab, slash, or cut.
Subsequently, the wound can be either a stabbing wound, a slashing wound or an incised wound.

You have to check depth and length of wound to narrow further down.

Double edged left, single edged right.

Do you mean this wound looks double-edged to you?. It was created from a single edged knife, as you can tell from the sharpness of the nearer extremity of the wound. Perhaps you were thinking one wound edge should be more ragged, but the skin has separated and wound edges have become more stretched out, reducing the contrast between the two edges. You don't see this in clay. If you looked at this under magnification, I think you could tell the difference between the wound edges.

It appears to have been created with a small single edge knife. The puncture doesn't look very deep. Some adipose tissue appears to be visible.
 
I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to.
