Grappling hook and rope

[JFutral]

Either I am just running into a bit of tough RNG luck or this is a plot device that I haven't figured out yet, but I cannot find or find to buy a grappling hook and rope. Where the heck are these things? I found one at the beginning and haven't seen one since.

 

Thanks,

Joe

I could buy some at Fort Deadlight.
