Thank you all for kind responses. =)
My concern with the Surefire line would be the brightness level. As he would be in a darkened control room, the intense light may not be welcome. Though perhaps, the red/green/blue lens filter might negate that particular problem.
LED lights are definitely an option, as they have been, in my experience, more reliable and easier to maintain as opposed to a torchlight. I was thinking perhaps a white ARC AAA Limited Edition for the times when he needs a very small discrete light that will show color contrast, and a turquoise (sp?)ARC AAA for other duties when vision in the dark is important. If I did choose to go with the ARC's, it would be in addition to a larger personal light.
My cousin is not very knowledge on the subject of knives, though I suspect he could be turned...in time.

As such, I'm not sure I should send him a sharpening system. With no sharpening system, I'd prefer to get him a nice edge-holding steel such as S30V or D2. One knife I'm actually looking into is the BM 921. I got one for my father's Christmas gift and was impressed. S30V blade and the modified Wharncliffe was surprisingly handy, not to mention the little hideaway slipjoint. However, as mentioned above, the ocean environment presents problems in terms of rust and corrosion. I wish I could just get him a Mayo TNT, but...YOU know.

I'm wondering if a simple knife care kit (Marine TuffCloth, TuffGlide [or lubricant of choice]) would be enough to fight off the corrosive properties of the sea air (as he would probably never find a reason to be in the water...God willing).
Thanks for the feedback. Cheers.
