This was an estate find...I do not know much about it...it seems like there is quite a following to these knives...Here\'s my best description:The handle is very clean...it has a dark brown butt, which will need to be tightened...there is horizontal ~1/8\" turn when deliberately pressured...
The brass finger guard is pretty nice, some markings of wear, but no nicks or offsets...
The blade looks good as well, there is a patina it looks like with darker spots on it...it seems clean though...
It is sharp, and it does seem to have two extremely small chips in it...probably smaller than the size of a needle head...Blade measure 5\" long, and about 1\" wide...entire knife is about 9.25\"You guys are the experts...Let me know if you have any questions?Hassle-Free Returns!Thanks for looking :)
