This is a study and comparison of how each manufacturer has slight variation in the same style small hook, my pick of preference. The variations of actual shape of hook, size and thickness. I think it's worthwhile this be pointed out as I see many noobs question how to make their own and ask for templates. I'd like to show that those templates are just guides and don't be afraid to deviate a little from them.
I've also included two of my own hooks I made from hacksaw blades. They are not pretty, but I get excellent feed back from them! So this is actually a look at 7 different variations of the small hook.
There are many more too! The Dino Navigator Set includes 7 different variations of the small hook!

You may laugh all you want at my home made picks, but you might be interested to know I get the best feed back and success with mine

I also have the Dino Navigator set, and also use them as well. It's really interesting how some hooks just work better in some locks, much like tension wrenches! I use them all at one time or another, my least favorite is Southord because they bend too easily and I don't like the size of the hook. You can even see a slight bend on the SO in my next picture. Say what you will, but it is what it is and none of my other picks have ever bent accept a few hacksaw blades that got over heated.
HERE IS A CLOSER LOOK AT THE BLADES

For those of you who like SO picks, you will notice that Southern Specialties is verry close to it. I like to put it this way, SS picks are like SO on steroids. The extra .005 really ads a lot of strength to them. I don't care how heavy handed you are, you won't bend the SS. I just find the SO too soft for me.
The best steel is of course Peterson, HPC, Majestic.
I prefer the slimmer shape of the hook on Peterson, HPC, and Majestic. It's what prompted me to try even slimmer hooks with hacksaw blades.
Compare the radius and shapes of the hooks closely. The thickness also is important. I prefer .020, but not on SO.
Hopefully this visual aide will help you decide to experiment with your own hook designs! I've done a fair amount and am finding there is lots of room to play with.
This comparison is hardly complete as there are other manufactures that are worthy that I just don't have at this time. I draw no conclusions accept to state what my experience has been.
