Or their sharpening machine may just use a weird geometry, so when you go back to sharpening like a man, you have to remove lots of metal to get back to normal.The trouble with letting your saw shop do it is that they almost always put the least experienced peon in the shop on that job. The work usually varies between questionable and downright bad, like receiving back almost-new chains with half of their life ground away.
