Horsefeathers;
This is probably the same blade that was used by the Muslim fanatics at around the turn of the century.
They would somehow bind up their stomachs, work themselves up into a lather (just as Muslim fanatics of today)., then run amok through villages, killing innocent people with those same knives.
Gen "Blackjack" Pershing had to deal with these nuts on a daily basis.
The .38s that the troops were using then, didn't stop those idiots quick enough to prevent further killing on the spot..
So the Army pushed for, and got the 1911 Colt .45...
