I bought a London Plane board to make my son a chopping board. The one-man woodshop ( https://mactimbers.com/ ) I visited had 4" thick boards about 15" wide. Heavy sucker. This was too wide to go through my planer, so I asked it he could take the waney edge off.
He fired up the biggest saw I have clapped eyes on. It was sited outside under a tarp. "I've only got a 30" blade in it, although it takes up to 48", which is a bit excessive". He fired it up, and with several distinct acceleration stages it became a screaming blur. He sets the fence distance and hoiks this monster plank onto the bed. It went through that chunky plank like a hot knife through butter.
He'll use a push stick, I thought. Nope. The last part of the cut he just put one hand on either side of the blade and pushed it through. I almost couldn't watch. SawStop? Not a chance. One slip with that sucker and a limb comes off.
