You are correct, I missed a photo. At my age it's a curse being deaf and dumb in both eyes. :thumbup:

I believe it's a less expensive model of a Hirschfanger. It would have originally had a leather scabbard that the closed knife would drop into.

Yes the knife does fold out to full length, but does not have a locking mechanism at that length. Possibly something missing to allow it to lock at that length. At the shorter length it locks fine. Then press the button on the side of the handle to release the blade outward. I never did remember seeing a scabbard to it. At least as far back as I can remember. But who knows, me and my brothers could have lost it when we were kids. I do remember playing sword fighting with my older brother with this knife and an old civil war sword, I think it was called the "old wristbreaker". My dad used to beat our asses for playing with them like we did. Now I know why he did. Needless to say they both survived our childhood and now I own them.

As for the folding knife I'll keep looking with the information yall provided so I can find out as much information about it. My dad always wanted to know what it was used for and where it came from (country origin and year). He is in his mid 70's and his health is deteriorating pretty badly these days. Hopefully I can pinpoint the exact origin about it before he passes away. He came by my house recently and was looking at it and just having some old memories about it. I really think that particular item is the one thing that reminds him about his father the most.

Thanks for the information

Bastet was a Dutch manufacturer of high quality cutlery and surgical supplies since 1684, located in central Amsterdam.
They went out of business only in 1981. At some point they changed the name to T.F. Bastet (around the last quarter of the 19th century), having been purveyor to the royal household for different periods of time (at least during the late 17th and late 19th century).

Doing my search online I found T.F. Bastet markings on speed skates from 1890-1900. I do remember the last time we talked about this knife I did find some shaving style folding knives. But there were not any that stuck out when folded.

I looked up the German style hunting knives / cutlass (Hirschfanger) and most of them had some kind of hand guard on it and they had some length to them usually around 20". I think the total length of my blade is around 12" to 14". So I'm not sure if it would be a hunting style, but the blade is thick enough to do some damage.

But they were definitely in Amsterdam. It be cool to find one that is close to what I have with some kind of description. I'll keep on searching.
