This new toy weapons are a gimmick, basically if you really want some emergency equipment but you didn't explore the environment for upgrades, you can buy this.
The pickaxe obviously is for cheesy finger dust, the nigga in love with Roland, in the gardenia's map, you can do some 100% exploring for a fancy and lethal pickaxe.
I've never recruited that companion because I think he is a kinda lame, and I like fighting maxed out super Roland and that conflicts with recruiting him so fuck cheesy.
Also I don't recommend investing in Georgy, he doesn't have any special dialogues as a companion post garbage island, but if you really want to he got a ton of new skills like Darry, if you want to cope
