you could re mill the head? I have used a hacksaw before it took along time though I think I would drive the 50 miles. maybe theirs a better way with a dremel if you have one. I use an 18oz stilleto framing hammer, made out of titanium very light but extremly well balenced, also an exchangable head.I can still drive a 3.5" nail 2 swings no problem, actually I usually set the nail then bam! one smooth smack ,that nail was wishing it was in someone elses pouch that day.
