I'm surprised the shaft is not keyed in some way. A couple of
opposing parallel flats on the shaft end with similarly keyed blades
and washer or cupped washer would seem a simple solution.

I'd say a stupid simple solution! But Nooooooooo Idiots designing
tools that never use them.

Flats wouldn't work--they'd lock you into a single blade orientation.
That's why the star, it allows a range of blade orientations.


Used mine, today, to cut 2x4's flush to another 2x.
No loosening.

Dang did the same thing today and used a power planner. Should have use the
Multi tool,damn. I have to remember all this thing does!!!

I looked at it and thought of drilling a hole in the round part that
receives the blade, Then sticking a pressure pin in there to line up
with the holes in the blades. (The Dremel's have a lot of them, evenly
spaced, 360 degrees.)

Just an idea.
