Mentioned this in another thread but thought I would share it here as well if people don’t know they exist. Wire wrapping pliers are a great tool for modeling. I use mine for all sorts of things. But if your making any sort of bent wire for plumbing, hand rails, or what ever these are a must have.
This outfit has all sorts of pliers that would have multiple uses. Mine are the stepped kind but I might recommend the conical type so you can bend any desired curve.
