Fourth Grade
That would make him, what, nine? Possibly ten?
Old enough to have a handle on right and wrong.
. . . he shot his first turkey a couple of weeks ago.
And old enough to make his acquaintance with nature.
I didn't receive my first knife till I was twelve, but this lad seems to be a little ahead of that curve.
Since he's only going to carry the knife at home and in the field, you can get a little more bulk without worrying too much about "pocket" issues.
While on the one hand I like the Buck 110, I would suggest -- if you're inclined toward that pattern -- that you consider the Buck 112 instead. It's scaled down a bit so it's not overwhelming. He won't outgrow it, but he also won't have to "grow into" it.
In the Case line, I have a special fondness for the Sod Buster Jr, a tremendously versatile knife, and still available in CV, as well as the Pocket Hunter (sorry, no CV) which is the size of a Peanut but both blades are the same size.
A small Leatherman is always useful, but somehow the "magic" of a first knife won't attach to one. Good tool, not what I would normally consider "that first knife."
A "boy scout" pattern (four blade, SAK style) knife, on the other hand, makes a great
first knife. Unhappily, I'm seeing prices that evoke sticker shock once you get into some quality. The prices of actual Swiss pieces aren't so bad, but Boker, Case, and others are a little harsh, considering what the knife is. Jay's knives has one of the "less expensive" Case scout knives I found:
see here, about 2/3 down the page. $70 bucks, so a little steep.
Even this one is over $70.
However, if
this one here is what it seems to be, then I would jump on that in a heartbeat.
And, of course
eBay has one, with a "buy it now" price of $20. (Actually, there are several. I should probably grab a couple.)
Anyway.
My final suggestion would be something like a Stockman pattern (Case has those in CV) or a Whittler pattern (the Wharncliffe whittler patterns, like the Case Seahorse, are among my favorites).
My first knife was a camp/scout knife (Imperial), received on my 12th birthday, and I still have it more than 48 years later. The next one given to me was a Holley Wharncliffe Whittler (when I was 16); I lost that one in England, I believe.
Understand that I'm only making these suggestions based on my own tastes in traditional knives.
More modernly, folks may favor a locking knife. And, in certain patterns (like the Buck 112), I would agree. (Buck, of course, does a whole range of smaller, lighter knives; they're all over the place.)
I can understand the reservations of others regarding the knife, but you've already cleared it with his guardians, and any youngster who has already had his first successful hunt can certainly learn to use a knife.
