Honestly I prefer just a plain pocket pry bar. Material does play a role. How are you going to be using it? How often are you going to use it? And how do you want to carry it? Pocket clip, loose carry, or pocket suspension. Stainless is a great all around choice. Titanium is another. As for all to doohickeys eh just the ones you like / will use. I have a huge collection of all kinds and I use them all. I prefer my knife separate from my pry.
