If your primary purpose is chopping don't buy a 6" bladed knife, period. As others have stated the strength of the S6 is that it is a "do anything" knife. You can handle tasks as diverse as prepping food or cutting tent stakes yet still press it into service chopping wood where it will do a credible job as WD stated.

It's a terrific knife to hike with because it is relatively light despite its size and yet retains a wonderful balance in the hand.
