I had posted this four days ago, hoping to get help figuring out how to open it, after a lot of searching I found the U S patent number 338,251. patented March 23, 1886. no mfg. marks or info
U S patent drawing link

To open it you pull out on the side of the knife body and lift it from its locking pin at the tip of the blade, then you rotate the body side CW and it takes the blade with it into the working position, continue CW and place it back on the locking pin.

    Thanks for sharing both the knife AND the answer. Having mastered the patent office you are now un-officially on our research team. Every third " un-solved mystery" is yours !

    It was by looking at old patents that where referenced for new knife patents that I found it. An interesting side point The patent was issued to a man with the last name Crandall. Crandall is the name of my home town, no connection though.

    It must have been a significant patent.

    Awesome! I just saw one of these at an auction a few days ago. I didn't know enough about what I was looking at, though, and let it slip by. Now I'm kicking myself. That is just too cool.

    Thanks for giving this old knife some love MichiganMillsJr. I appreciate the comment as well, it's too bad you hadn't seen this post a few days sooner. I love getting this out to show people & watch their frustration as they struggle to find out how it opens.
