Hello Kubur,
I just see that I forget to post the size of this knife

it size 13 25⁄32in so longer than the majority of bou saadi ?
The knife fit perfectly the scabbard so I think it more close to a flissa than a bou saadi (with a leather covered wood scabbard).
The steel using or the blade is also different from this one used for the bou saadi and flissa, looks really different but it could be just a misconception of my mind !
I've seen the post on the forum speaking about forge marking, and don't have seen this one. And I'm note able to identify what it represent/symbolize. Is it a trident a crown or something else
