Stiletto,
The regulation your looking for is USMA Reg 190-13, Physical Security and Crime Prevention. If you can't find it on the USMA Intranet, call the Provost Marshal at 938-4585/5207 and ask for someone in physial security and ask them. As a plebe in October, you know better than me if you have any spare time to go to the Provost Marshal's office in person to look at the reg (fat chance). A Randall, huh? I can tell you THAT is going to be too long (blade length)for keeping in the barracks. I've seen the local regs vary from folder lengths of 3" to 5" being allowed (fixed is different). As an example, here is part of the regulation here at Bragg (from FB Reg 190-12):
Chapter 9
9-1. Prohibited Items and Prohibited Acts.
a. Except as otherwise provided, the following items are prohibited on Fort Bragg and deemed contraband subject to confiscation:
(1) Prohibited Knives: Fixed blade knives having a cutting edge in excess of two and a half inches, except when carried openly in the pursuit of a lawful purpose such as hunting and fishing. Any stiletto, switchblade, gravity knife, bowie knife, sword, or spear is prohibited. Nothing in this prohibition is meant to apply to household utensils such as kitchen knives, ice picks, scissors, meat cleavers, carpet knives, pocket knives with blades up to five inches in length, wood working tools, and other similar items when they are used for their intended lawful purposes. Tomahawks, swords, or other similar items are also exempt from this definition when used exclusively for ornamental, ceremonial, or sporting purposes.
Now, I'm not saying that I agree with it, like it, or am the author of the above...just providing it as a reference.
2.5" fixed blade length--this is more restrictive than many Posts, but their is always a caveat to this (at least for soldiers that aren't in a TRADOC environment). Most fixed blades (to a degree, I guess: good guide [that someone else on here used] is 7" blade length max) are allowed in the field, but not in garrison...I keep my personal M-9 bayonet on my LBE...but it stays either in a locked locker at the office or at home when I'm in garrison.
Could go on, but this is turning into an epic. Understand that as much as you like individuality, a plebe in October ain't gonna get much of that--we want to ensure that "you" understand the welfare of the whole is more important than the individual. Before you know it, though, you'll be out of Hudson High, and your responsibilities and decisions will increase (and affect) others ten-fold. So concentrate on that (and remember that you learn things from the good AND the bad (or idiotic).
