Well Williard, I've got to say that you and Willie (SOTC), and John Emmons, (Highly respected Old-Timer at our shop), can't all be wrong. I remember the first time that John got a good and deep belly-laugh at the sight of me butchering up a good round-ground chain to "convert" it over to my double-bevel file. "That edge will never stand up to residential work, Jed," he said. Ah, well, all you guys can't be wrong, except that John takes the whole issue one step further, and insists on the Semi-chisel stuff.
"Keeps it's edge way longer," he insists.
Ah, who knows... they're probably right. ................ All I know is, competitive fellow that I am, (God forgive me), I'll bury my tired as heck little 440 with a full-skip square grind, 28", and beat any of them boys.
I trust you about the comp saws though. Stands to reason: if you've got the power to shovel the chips, then cut more off, and the job goes faster. Still... I never really understood the argument about sharpening time. True, I have to take the gullets out with the round file, but, outside of that, if you use the triangle (hexagonal file), and you just barely graze the tie-straps, with a 30 degree downward stroke from the front, you can keep consistent angles, AND finish the chain just as fast. The goof file is even faster. Faster, I swear than even a round file, and if I could post vids, I cld proove it. To bad that you and Tucker would be the only souls on this green earth that would watch it!
