Keen Kutter pocket knife experts?

I'm working on a book that is based on a WW1 soldier's diaries and letters home. In two letters to his mother he requests that she send him a pocket knife. He's rather specific:
Not being an expert in such things, I was hoping one of the group here might be able to help me identify the exact model he's asking for. The letter is dated 1918. It's unclear from subsequent letters if she ever sent him the knife Anybody have a clue?

Wow. Very interesting. I have no idea, but good look with the book and identifying the model.

Keen Kutter has a devout following, as their knives and tools are quite collectable. I bet there are some online references out there.
I have a book on antique pocket knives, I will have a look this weekend.

You can pick up this book for about $10 used - http://www.amazon.com/Kutter-Pocket-Knives-Schiffer-Collectors/dp/0764318942

I have one of their razors, and it's one of my top 5. feels almost as good as my MK 31 in the hand.

Well, I got my hands on the Keen Kutter knife book, and it pretty much has to be the Scout Model knife K6559 (late) made from 1913-1939. Has a sabre spear blade, can opener, combo bottleopener/screwdriver, and leather punch.

It's a bit surprising that he didn't call it a Scout knife (as in Boy Scouts of America), but I suspect he saw and admired one owned by someone else (maybe a former Boy Scout?) when he was already in France and just asked the guy what brand it was.

Eh, wished I had seen this thread back when you started it.

Here is some information on Keen Kutter but it sounds like you have found your model. The scout models are indeed quite handy to have around.

Anyway, here is the link
