All About Pocket Knives

I went to an estate sale this weekend and was asked about what I believe is a KA-BAR 62156. I am not certain of the handle material yet so the "6" may be wrong. It is a pocket knife with a blade and a mini-axe. Maybe 5 1/2" closed. Some tarnish on the steel, no pitting, no cracks, and it appears never to have been sharpened.

It is KA-BAR spelled with all caps on the tang of the axe and "Union Cut. Co." on the blade. It is in Straightline Mark. There is no dogs head shield.
The handles appear to be black; maybe compostion; maybe bone, I couldn't tell. I only saw the knife briefly and have asked for digital pictures which I'll post later.

The owner wants to sell. I am not interested in buying it. Just thought I would help this guy before he posts it on eBay or wherever.

If you have any info or interested, let me know.
Thanks,

Jim

Pattern 62156 should be 5 1/4" closed.
Handle should be Bone Stag.
This info is in my 1984 price guide, price back then with the Straightline Mark was $550.

Reason I used this one to look it up because it does have a picture.

My 2004 Price Guide list the same pattern number at 5" and says it is valued at $325 (Mint Condition of Course)

My 2000 Price Guide lists it at $325 as well (mint)

So it would appear it went down in value, I would assume with the age of the interent, maybe they are more abundant than thought in the 80's?

So in MINT Condition I would say your looking at $325, with the tarnish and what you described, I don't think your looking at a mint knife, so based on good-excellent-Near Mint, you will have to go from there.
