Sonicrafter with Hyperlock a great tool
It took a few minutes to find out how the hyper lock works properly but after finding that you tighten the lock and then turn it 90 degrees to the tool and rotate until it can be folded down in its proper place. After that I didn't have a blade loosen again. It was my fault but now I really like the tool and am trying to find jobs to try to stump the tool. It does it all. Love it.
