I'm interested in having a custom wrench manufactured and I'm hoping you can assist me with this project. I need to discuss the specific design, materials, and any unique features that might be required to meet my needs. Could you provide some info on your capabilities regarding custom tooling? Additionally, I'd like to know about your lead times, minimum order quantities, and any potential costs involved. Looking forward to your response!
