Straight Flush Saw
Until I read into the article a bit, I had never heard of a worm gear saw in my life. And I have been around construction folks most of my life. I can see that this saw is going to be a huge seller and and speed up construction projects everywhere. As the headline for the post claims "Swiss Army Knife of Circular Saws", I believe that to be true.
It is one impressive piece of hardware to have in your shop.
