Modular pyrophoric lighter

A modular pyrophoric lighter includes an outer case, an insert removably received by the outer case, and a renewal module removably received by the insert. The renewal module quickly slides into the insert to provide a new fuel supply, wick, and flint. The renewal module quickly slides out of the insert when the fuel, wick, and/or flint is spent so that a new renewal module may be installed. In an alternative embodiment, a modular lighter includes an outer case, an insert removably received by the outer case, and a fuel module removably received by the insert. The fuel module quickly slides into the insert to provide a new fuel supply. The fuel module quickly slides out of the insert when the fuel is spent so that a new fuel module may be installed.
