Well, i may be a little late in regards to replying, i havent been checking up on this forum since surgery, but heres just my 2 cents...ive been in the Army now for 4.5 years and as a medic with an armor unit (constantly around vehicles) if he aalready has a sharp/maintained/"hasnt lost it yet" pocket knife hes already light years ahead of other new guys (dont know how many times ive argued during downtime why my buck 110 is hundreds if times better than a 2ft cold steel rapid action quadruple lock tacticool knife) i was given a SOG multitool by my dad before i left for basic and issued a gerber from rfi, and that is pribably the single most used tool in the army (at least) so much as to the point where all multitools are considered "gerbers" (regArdless of brand) and its extremely common to hear things like "hey (joe) lemme see your gerber right quick" so with all that nonsense said and wasting your time il get to the point, he's prolly gonna open a lit of boxes in garrison as well as other meanial cutting tasks, and open alot if "brown bags" in the field, so that pocket knife is gonna get some time at hand as its easier to open crap up with, and a multitool is going to see an equally large amount of use, so honestly you should get him something like a slim pocket slip for his pocket knife and a multitool but make sure its in a black belt sheath, leather is not allowed on our belts, unless youre a tanker or tanker medic, and theres other off set rules like i can wear multiple sheaths fir trauma shears multitool ect because im attatched to infantry ect, but the safest bet is a black sheath which is universally accepted, but he wknt want to give up him pocket knife either, so might as well let it ride cozy and somewhat protected, sorry went off in space on the reply i apologize, but good luck and regards to him and yourself
