Age old debate, it seems.
Here's the ticket, at least in my experience.
Carry pocket tool because they are useful, used, and sold commonly in the PX system. Not necessarily seen as "knives" and for good reason. They are tool.
Carry hardworking folding knife of reasonable and usable dimensions. Carry on uniform pants belt or in pouch on LBE or combat vest where it is out of sight and out of mind.
Carry good quality fixed blade of between 5" and 7" blade. This can go on combat vest or LBE. Nothing fancy. When you're shipping home just pack everything up nice and neat and don't make an issue of it.
Yes, the idiots are out there and they play their games because they can. However, twice now in Iraq and I've seen combat knives carried by all forces without concern.
The "rifle" and "knife" thing is old argument and pretty well worn out. Hey, some CO wants to store a buncha knives in the arms room, fine with me. It's CYA and that's okay as long as I have to live under his/her roof. Professional soldiers don't need a knife, or a rifle, or a grenade, or a pocket tool to take care of war fighting business. Just the proper training to use whatever is at hand.
(I did like the "her kitchen knife" story. Good reason to lock up everyone else's but "her" dinner utensils, if I read that right. Thank goodness the E4 - and it's always an E4 it seems - didn't strangle her with a pair of her own panties, yes?)
And if there isn't quality training in knife use in the unit there should be because you're issuing bayonets and allowing combat knives to be carried. But then, if such training IS provided I suppose it becomes even more important to lock up every sharp object that might be found in the barracks...damn!
Buy a pocket tool; buy a nice quality folder; buy a KA-BAR or something akin to it; and work on the basics of keeping yourself and your soldiers alive in combat.
'Cause the simple fact is this - too many officers and senior NCOs are worrying about nonsense like "knives" when they should be ensuring their young troops are getting real world, reality based war fighting training in prep for bad places like Iraq and Afghanistan. When they're spending their time and energy on getting dirty with their troops learning how to lead and fight with them, they haven't the time nor inclination to worry over "knives".
