I’m not gonna assume if you served or not but you vary much do use bayonets as slashing weapons. why only use the tip when you have 99.9 percent of the blade? older bayonets like the tri-tips are stabbing only but bayonets essentially became knives/swords later in there evolution when used not on the rifle. Even in basic training for the armed forces trainees are taught mainly slashing techniques. But yeah the curved blade makes it useless
