Peterson is my go to for functional picks.
I use hooks more than other picks and this set looked to fill a niche otherwise not covered in my tri-fold case.
"Our Hook 3, Hook 4, and Hook 5 in Government Steel with plastic handles are conveniently grouped in a plastic tube. Grab the set, and save some money! Bosnian Bill says, "For: Accessing very deep cut pins in Euro locks. My opinion: Very Useful. Not used every day but indispensable when you need them."
I have not used it on any Euro locks, but deep cut? Yeah, these are very useful.
I had a schlage lock at work in which the last pin was the deepest (6) but not the last to bind; I had to reach it before being able to manipulate the first stack, which was a smaller pin (3). These guys worked it well.
