Said he picked it up at a hamfest years ago.
Around here, most commercial stuff is crimped.why would you crimp rather than solder ?
Stopped by my dad's today, told him I needed to order a crimp tool. Opens his drawer and whips out a real nice crimper along with 6 silver crimp on PL's.
Made me happy, didn't think he had one as he always solders his stuff.
Also lower possibility of doing damage to the insulation as well.
