Cool! Glad it helped. There is 1 more moment, I circled it in red, in the same places there is some kind of mark. In the photo from the website, this place is smeared with dirt / rust, but something is there (or it seems to me), maybe it's just dirt or rust, but if this is exactly the mark and they are identical on both knives, then it is possible that they are brothers.

Great flashlight, I have gone to HDS for now
