i can hand sharpen an 18 inch bar{ including: filing bar, touching rakers, sharpen teeth} in about 8- 10 min. never used electric, thats just one more thing for me to lug around.{sounds nice though} my climbing saws Usually seem to hold chains for longgggg periods of time. bigger ones on ground that cut more than wood for some strange reason seem to have a far less duty cycle. I try to change my sprockets every 8-10 chains. thye say the better condition the sprocket the higher the torque. sloppy sprocket=worn drivers=not so tight operations=excessive wear=money
