I've had the oregon style stuff for about twenty years. Much prefer to do a light touch (1 or 2 strokes per teeth) up each use. When you re learning it is easy to over sharpen and the saw starts to cut curves(towards sharp side).
The tricky part is use. Real railway sleepers (red gum or yellow box) means one cut = one use. Really tough stuff.
I also carry falco/felco 6" folding saws for up to green logs ~ 9". Excellent and quick compared to chain saw unpack, suit up, use, clean up, sharpen, repack.
Thanks for the packing ideas.
