Hi Jef, et al,
I had a look at my two saws, table and hand-held, and both have a 'shark fin' rive as standard. I never really noticed them until now but saws without them look very weird to me.
The table saw had a plastic yoke on the top of the rive but it broke so I got rid of it. It didn't add any safety to the saw. The remaining rive only comes to the top of the blade and is mounted on the motor/saw frame so it's stays with the blade. It's a "cheap" saw but was easy to set up, and holds the settings well.
Tis one of Lidl's finest. :) Light weight but I only use it for light stuff.

I like riving knives, it's nice to see if/when the cut closes after the cut but never binding on the blade.
