Unless you really torque it, the blades tend to vibrate loose.

I thought this was THE major problem with the HF units and made them no
bargain. Has someone figured out a solution or are they OK if used
only in the occassional home DIY environment?

I've never experience them coming loose.

Apparently the old "multifunction tool" (the one I got for $35 recently)
has this problem. After looking at the mounting system for the cutting
tools, I can see why: there are 4 little nubs on the mounting plate that
could easily get worn down.


As the nubs go into holes in the attached blade, how are they going to
"wear down", unless you mount the bald incorrectly? Do you expect a
problem with keys in keyways wearing down?
