What factors make a cheap, should-be-junk lock hard to pick?

You havent offended me, youve simply misread my post,

I think that even cheap padlock can do some unpleasant problems. For example my FAB padlock. I picked them once time. Since this success I never picked this lock successfully again - still traying

Sounds like the first time I blew a smoke ring... On the first try.. BAM! perfect ring. Ever since it just comes out completely the opposite of a ring.

I think that might be even more impressive.

I know you said you threw it away.... but......

When you said the pins still moved.... I was under the impression
that you meant when you were picking it still.
(You get a better feel than with a key)

Did you try the key in the sawn-off knob afterwards?
If so, how did it behave?
