Can this be demonstrated in an even more dramatic fashion.
Oh yes.
In 2011, the US murder rate was 4.7 per 100,000. According to FBI statistics, there were 33,911 murders in that year. 1694 of those murders were committed with edged weapons.

Do the math. One in 20 murders in the USA were committed with edged weapons, yielding a murder rate by edged weapons of 0.23 per 100,000.
The graph above from Statistics Canada shows an edged weapon murder rate in Canada of 0.6 per 100,000.
How can that be? Are there more knives in Canada than in the USA?
Obviously not.
It shows that killers will kill. If they can get a gun, they will probably use that. If they can't get a gun, a knife works very well, thank you.
