Punal size and construction

Gentlemen, you are of course correct, a 1 cm deep laceration can be fatal if it is in the right spot. My comment was,

reliably cause lethal damage

in other words lethal without having to hit one of those key spots. Kino, your comment about winter dress in the Philippines is also very pertinent. I have some experience of knife wounds having worked in ED departments, I recall treating 7 stabbings on one particularly busy Saturday night.
