A Rednecks work is never done.

You have two types of engineers. The first is the kind who sits in a corner, idly whacking away at clunks of metal. The sound echoing off the walls for hours on end, slowly driving them mad.

The other is the Offensive Engineer. The OE is spawned from being driven insane from the first. They build sentrys then abandon them like babies on a church door step. Leaving them to fend for themselves. Or they randomly run into enemy bases to build, or throw level 1 where ever they feel like it. Constantly assulting Medics, Demomen, Snipers, and Spys with wrenchs when spotted.
