Shopping at Blows and Homeless Despos again ?
I've used the Milwaukee green blades and the newer ones (I think Lenox) made for pruning.
That video shows cutting dead wood (and soft wood at that), not green wood (notice how the "evergreen" trees have no green on them). That's why it is working so well (being frozen may help as well). Green wood weeps water when you cut it, and gums up these blades.
The pruning blades are designed to cut green wood. They're a crosscut blade with a tooth pattern similar to a "Great American" saw, but like I said, the sawzall stroke severely limits their capabilities.
If you're pruning smaller branches, or dead wood, you may have better luck with the Milwaukee "Super Sharp" Swiss made fleam blades. They're a more aggressive cross cutting blade, but have less chip removal ability, so will not work on green wood thicker than the saw stroke.
Sounds like you need a real sawzall there chief. A cordless compared to a chainsaw will leave everyone disappointed in the sawzall. I use a full size corded sawzall with the orbital action on full throttle. I will say that I am obviously not talking about cutting down a black walnut or some other hardwood tree. These are softer woods like aspen and cottonwood.
And I obviously don't sit there with a stopwatch and time myself, but yes roughly a minute it would take and certainly under 2 minutes.
I have a real sawzall, but dragging a cord around to prune trees was just not worth the effort. Totally agree that my cordless was way anemic compared to a real corded tool (but that was years ago with a NiCd; today's cordless closes the gap a lot).
The last time I tried using the sawzall pruning blade on something big, it was on a white oak branch, around 8" in diameter that fell in my back yard after a storm. The cordless was not doing it, so I pulled out an extension cord, and finished the job with a corded sawzall. It took several minutes, but did work.
When a noreaster hit on a Saturday several years ago, it left me a big mess by dropping one of my cherry trees (16" diameter at the trunk). I was waiting at the door to my local Ace hardware Sunday morning when they opened, ran straight for the shelf where the Stihl saw I'd been eyeing for a long time was, and was out of there in 5 minutes with their only one of that model.
Never looked back at the sawzall blades again.
For me, my "chainsaw" is just a pole pruner attachment for a Stihl Kombi. The tiny 12" bar is still plenty capable for me, and is comparable to at least any electric saw out there.
I would say that while a sawzall is a capable tool in a pinch, someone who already had an electric saw would be woefully disappointed downgrading to one.
