It depends on which locks you're going to pick
It surely looks like a good pick (I don't own one though), goes a long time and have heard good things about it, here on the boards too
viewtopic.php?f=8&t=26159 and on the net and it'be the only Curtain pick you're going to need, though I can't be too sure because I may be overlooking some nifty other brands' tools.
Cheers
