Read some of the OPs posts in other threads, then the reason for bringing this up just might be a bit more clear....

Most any knife that is a pocket knife by common definition or that is defined by statute as legal to carry where you live could also be construed as a weapon if used to commit a crime. Most any object that can be used to commit a crime against another person could be defined in court as a weapon if the specific intent of use at the time the crime was committed was to inflict bodily harm or instill fear.
Some knives are weapons by design and have no real purpose except as a weapon.
Swords are not knives, they are edged weapons designed for the specific purpose of warfare.
Every state in the US has laws with specific definitions, as do other countries. If anybody has a question as to what is a weapon and what isn't, just read your General Statutes and find out. Opinions don't count in court.
