Gabby, The only time I can do a 180 spin move is when I have a very small blade like #2 or something. If I try it on the larger blades then yes, BYE BYE blade. But with the small ones do it just like described above, back out just a bit so you're not cutting forward, spin 90, 180, whatever and go, I do it all the time. RPM doesn't seem to matter much from what I have experienced.
