In Punisher MAX (a comic book) a character's hand is sliced off in a single swing (seen here - warning graphic content).
Is this actually possible for a human to accomplish this?
If so how much force would it require?
The reason I'm skeptical is because there doesn't seem to be a clear point in the wrist where an amputation like this could occur (seen in xray below)
In addition, I there isn't much research I could find on treating traumatic hand amputations, so they seem to be fairly uncommon.
In spite of this, ncbi claims that traumatic hand amputations are fairly common, "Traumatic injury is the most common etiology of hand amputations". (https://www.ncbi.nlm.nih.gov/books/NBK551692/)
Unfortunately, I couldn't find any statistics on the causes of amputations, so it's still unclear to me to what degree (if any) knife injuries are at fault.
