ID Help - Case Tested XX Hobo?

[outdoorjoe20]

I found this in my Dad's collection and I think it's a Hobo knife, but haven't found much other info.
I'd appreciate any information and the best method to clean it up.
Thank you!

Welcome to AAPK. Your knife is indeed a Case hobo slot knife. Be very careful cleaning it up. Some think they want them shiny like a new knife, but it’s an old knife and should look like an old knife. That does not mean it should be dirty or rusty however.
Here’s a link to info about whether or not to clean it, how to clean it, and how much to clean it. Most of what I can see in the pictures can easily be cleaned using the “lead” end of a pencil. viewtopic.php?f=37&t=54157

Welcome to AAPK and thank you for posting your pictures,

I believe your knife is a Case Tested XX 3352. Is the length when closed about 3 3/4" ?

There is another hobo pattern which is longer at about 5 1/4" and the pattern number for it would be a 6251. The 51 has only 2 utensils - a knife and fork. Per my observation, which is a long way from comprehensive , the 52 like yours with a knife, fork, and spoon is more uncommon to find. To me it looks like it is in great shape and just dirty so soap, water, and elbow grease might make a noticeable difference. If do end up using water make sure to dry it really well and wipe some oil on the metal parts.

Thank you both - I appreciate the information!

The length when closed is about 3 3/4" - so I guess it might be the Case Tested XX 3352.

Thanks!
