First saw i used was my dads Pioneer-Partner p-39 plus, my grandpa sold them at his hardware/convenience store. He started with Partner, then when Pioneer and Partner became one, he sold them until the brand was done away with. I now have one of my own, built from parts from smashed saws a local logger gave him,(I now work for the guy, haha). Between dad, grandpa and me we have 6 of them and they all see wood often. I guess i could say the p-39 is my favorite too, because I think of cutting firewood with my grandpa when I was first learning, and it makes me smile. I know I'll be running these saws long after he's gone.
