Anybody ever try to survey for this guy? 😉
I just keep an extra chain on hand, they are fairly cheap.
It's sad how few people know how to sharpen steel. My grandfather taught me the art. Once learned, you can apply it to any cutting tool.
Dad, Grandpa, and Great Grandpa were all loggers. We sharpened chains differently for hardwood and soft. A little bit more aggressive for the latter, a little less for the former. If the saw didn't pull you into the cut, it wasn't sharp.
I abhor the waste from people unwilling to maintain equipment. A little bit of cleaning and extra attention to moving parts and most small engines will last decades.
I've found that the younger kids overcomplicate sharpening. I remedy it by giving them the time to practice. In the beginning I will have them take a marker and blacken the cutting edge so they can see how the bastard file strips metal. Once they can operate a file correctly (evenly), I teach them to think about it like polishing something until it's shiny. Stropping never hurt anything either.
