am i the only one that's having this problem? ive went to all the vendors that sells the mods and i cant find it anywhere

Have you tried the Van Graff's? Its strange that they would have it, but that's where I find all of my Katana mods. If not there then it might be in the Dino Bite in Novac.

yeah i've been there. i heard chet and cliff brisco change their inventory everytime you leave their place and come back, but they never have it

i finally found it, i had to keep buying stuff from van graff then leave and go back in a couple of times

Did you try Mick and Ralph's? That's the only place that I've ever found the Katana. I know you already found it at Van Graffs but I'm just curious.

Mick & Ralph's, Van Grafs, & the one in Novac are a common place for it to pop up. I find anything related to the blade to be quite rare in any stores inventory.

a random traveling merchant yes realy he had a gra mod in stock if you think thats wierd then how about buying from old lady gibson out back behind helios one by the solar arrays while she's sitting down in mid air
