Steel is a little soft
Not available in many places
It's a classic design that has been around forever. It is made of steel, which gives it a hefty-ish feel. You can almost always find it right away. It has the little hole on top that soloists and people who like to think of big wall hauling trickery will like (I never use it). I have used this fifi hook more than any other and dig it.
The steel is a little soft. It is possible to bend it if you are not careful. This has only happened to me once, but it's something to keep an eye out for. It is also a little hard to find, although they usually stock it in the Yosemite Mountain Shop.
Any aid climbing or big wall situation.
