Need a gift idea for my blue collar babe

I am looking for a gift for my partner. We are somewhat new to the whole dating thing but I want him to know that I'm thinking of him. He's a badass pipefitter / welder who has an obsession with any little gadget or tool. He is obsessed with Knipex and Milwaukee. The only problem is that he pretty much has it all...nothing over 150 bucks I'm over to any ideas / suggestions.

Thank you 💓💓💓
