Items And Loot Archive

During these themeparks you get a few items that seem to be useful, like chemical release duration mechanisms, lightweight vibro blade units and such... But as a non artisan I have no idea of how useful they are, if at all, if they're valuable or not. I know I have no use of them but I don't want to throw them away if someone can make use of them.

Could anyone tell me this and maybe suggest what I should do with them? Destroy, auction et cetera.

The items in question are:

Chemical release duration mechanism

High capacity blaster power handler

Lightweight vibro blade unit

Modified dispersal mechanism

Thanks.
