That'll do it, Mike. Rocks, metal...if you're cutting and see a spark? Might as well get the file out & start sharpening. The saw shop here has rolls of chain...different sizes and teeth, depending on the saw and it's use. Mounted on a wall, like rolls of wire in an electrical shop. They just use the length needed of the proper stuff when replacing a chain. OREGON brand chain is still the favorite of the cutters here.

I'm fortunate to have a friend who is a pro cutter. He gave me some tips. Now I know just enough to be dangerous. Be careful!

(edit) Thanks for the link to the Oregon site, Russ...great advice there. It covers the basics well. I'll admit it, when I get into the big diameter trees? I call Lonnie, the pro cutter I know. He recently fell some 4-5' dia. trees for me. It's a joy to watch a pro work. My saw is a little homeowners saw. I don't like to mess with anything much bigger than 2' trunk diameter. Lonnie, who has logged for decades, knows what he's doing...I scare myself.
