Kitchen tools

Iam very new to baking, got a late start at 65 yrs old :O) So I was over the top excited when I found and purchased an odd handled thing called a dough wisk. I purchased two as my girl friend was complaining about hand mixing dough, and how it hurt her wrist due to arthritis. OM GOODNESS we are both thrilled!! How this was invented I’ll never know …but they knew their stuff :o)
Thank You

I’m confused, I’ve always read never to use metal with sourdough and yet this mixer has metal. I’d appreciate clarification please.
