Well it doesn't vary by that much .

Thanks Tom I have learnt something.

Now I know why not so many people talk about it. And also now I am reconsidering the saw back idea as a whole. There are a number of small folding saws in the market that I think will not take much BOB space beside the knife.

Any comments on the second knife (the Tracker) and why it is designed this way ? Why the blade is divided in two halves like this ? And is the saw back of the Tracker any good ?
