a few things:
a thin, not-too-pointy blade (i had my first knife confiscated by my father many years ago after cutting myself mildly after a short time)-gotta be able to whittle. make it an easy safe locker or a nice stout slipjoint. i'm thinking that a clipless, carbide glass-breaker-free (since it's unnecessary), thinner and shorter-bladed PE assist I (the whistle would be a great feature, also, the tip guard might not need to be quite as thick-just enough so as to make it hard to accidentally stick oneself) ergonomically scaled to a fairly small size (e.g. dragonflyish) in frn would be nearly perfect, especially if a dyad-style opposing can opener could be incorporated. a thin, flatground, fairly tough and corrosion-resistant (we're talking about in many cases, fairly young folk who may not have the reverence some of us have for not leaving a fine tool in the rain/mud)-maybe an ats-55, aus-something, etc. h-1 is probably overkill, but you know how a young scout can be. build quality should be on par with other models-it's important to instill in the youth a healthy respect for a quality tool. maybe even a simple sharpening system w/sheath that can carry both knife and sharpener (though the sharpmaker at its price point is right nice as is). no need for serrations/saws i don't think, as there won't be need for more than one or two hatchets/saws/etc in a standard troop. the real trouble is getting all of these features together at a pricepoint that is reasonable for most scouts' parents. (there are plenty of fine small case knives that are popular in this demographic) i'm thinking that a 2.5" blade and 3.5" closed is a fine size, and should be legal just about anywhere. might have to skip the tip guard or at least be easy with it so as to allow a little tip-work when whittling/etc. i love the kiwi design and think it could work, but perhaps in a more synthetic handle stock, more obtuse tip, with a whistle and opposing can opener.
i think that's enough rambling toward that end for now.
