No they are super stiff, one of the reasons I preferred the preceding lock system on
the tool. I bought a new version with piano locks emptied the tools out of it and
it stays in my garage and makes a great wire cutter. I took the tools and used them
to mod out my other Sog's.

Not sure I really understand what you mean though, if you can't make the tools fail
then how would the piano locks be weak?
