All About Pocket Knives

Hey folks,
I recently got this Marbles boot knife at an estate sale but I can't seem to find any information on it anywhere, either in pictures or for sale. I believe it's an older knife, but I don't think it was ever used or worn, as both the sheath and knife are in perfect condition. Curious about age, value, rarity, or really any info.
Thanks,
Will in Idaho

I think those were made by Camillus. It is a modern knife. I don’t think they are very common.

Those were introduced in 1982, The Western stamped ones are the most common. Nice find!
