Soldering Iron
Soldering irons are allowed in both carry-on and checked bags, since they're a heating tool without a blade.

Checked

Carry-on details
Allowed. A soldering iron has a heated tip rather than a cutting blade, so it doesn't fall under TSA's tool-length restriction the way knives and bladed hand tools do. It's screened like any other small electronic device.
Checked-bag details
Allowed. No restriction in checked baggage.
Special instructions
Let the tip cool completely before packing, and consider a heat-resistant sleeve or case to protect your other belongings from the metal tip.
FAQ
- Is a soldering iron treated like a bladed tool?
- No. It has a heated tip, not a cutting blade, so it doesn't fall under the tool-length restriction that applies to screwdrivers, chisels, and similar hand tools.
