I have a question about two survival knives. 
First the pilot survival knife 
 
 Why is it not mentioned often in discussions like this one ? 
While I am not interested in it for the purpose stated in THIS thread , it seems to me like a very verstaile knife, with saw teeth on the back, and two holes for making a spear , and the butt can be used for hammering. 
It looks like a great design in my opinion. 
Even the price isn't that much
Do you see anything wrong with it ? 
OK, the other knife is the tracker.  
 
 I keep wondering 
Why the straiught edge is divided in two parts ? 
Also, why the saw edge is only half of the blade length ?
