What's the difference between the Tom Brown Trackers knives?

Just as the title says what's the difference between the 3 Tom Brown tracker models?

 

[stabman]

Full size, about 6.25 inch blade length.
Smallest one has a 3.4 inch blade (don't believe the TOPS specs...they're wrong)
The other one will be somewhere in between for blade length.

Also, the thickness is different: 1/4", 3/16", 1/8"
