Dust collection aside, my issue with riving mounted guard is the fact that I am removing the guard often for buried cuts. The riving knife is recommended to be above the top of blade which also improves clearance for clamps etc to not interfere with the knob that secures the guard in the riving knife.

So on my KF, I have resorted to keeping the riving knife below top of blade so I only remove the guard for buried cuts.

I have recently acquired K975 with overhead guard. I have not used it yet so will see if I am going to be happy with it.

?If you figure out the answer, let me know.? The stock riving knife mounted guard with small dust port works okay, but misses quite a lot of the dust.? I've toyed with either making or buying an overarm system that accepts a 4" port. ?

I've looked at the shark guard, which isn't bad, and has the advantage of custom, 3D printed dust ports.? From YouTube reviews, it seems to catch most all of the dust.? I would think with "whiskers" such as these attached, it would catch most everything.
