I had no idea what he was doing until 3:20 mark. I thought he was making room for a hydraulic jack or something. No, that's pretty cool.

So is that chainsaw surgical sharp or what? There's no way I could make those cuts with any chainsaw I've ever owned.

When I lived up North, I cut and burned 5-6 cord a year. Keeping a sharp chain makes all the difference. A sharp chain is not only faster, but easier on your saw. Sharpening was just part of each day of cutting.....and sometimes during cutting.

He's likely using a chain with fewer teeth & no antikickback teeth will cut very fast. Also the saw motor is worked over to run faster & stronger. It's a good idea NOT to use a saw chain without antikickback features unless you are very skilled & willing to take the risk of getting very hurt. Tree guys I've talked to have saws that are very fast cutting but unsafe for the average person.

That's interesting. I hadn't thought about that.

I've always had a problem with the anti-kickback bar on every chain saw I've owned since they started putting them on the bar is so close to the handle I can't. get a good grip on it without tripping the kick back SO I generally have to heat the plastic bar enough to reform it to have a little more clearance or just cut the thing off. These wimpy little 50 to 65 cc saws I buy don't seem to have enough power to kick back anyway.
