Hands of Steel the 1985 Italian actioner, mixes Terminator with Over the Top and Road House. It features John Saxon briefly and it's in PD
I summed it all up in the title. Hands of Steel is a 1985 action movie shot by Italians (dubbed in English),but filmed in Arizona. The plot is Terminator meets Over the Top and with a touch of Roadhouse (one barfight). The movie barely has John Saxon in it and it is in the Public Domain. Found it buried in one of those 50 movie packs

Very much seconded. If it helps its case at all, the protagonist is a killer cyborg named Paco, most of the film's plot involves him arm-wrestling truckers, and John Saxon chases Paco around with a gun larger than he is while giggling maniacally during the climax, Hands of Steel is rad.
