In my case there is all the time a will for getting something better. Just think about it... just think about what would mean a 1 millimeter thick knife resisting as much as a fat Battle Mistress and furthermore keeping the edge shaving sharp after chopping rock or digging into rocky ground... In this case your thinner knife will absolutely cut better and weight less. Instead of its own weight, you might think of a system of adding to its blade weights that you find in the field (for example rocks) in order to have the proper weight for effectiveness in chopping. And that knife would never weight you down. Of course, what I'm talking about does not exist and is not achiavable with current technology. It's just my fiction. But I want just to say that always there can be something better and which can make your life in the field easier. The thicker your knife, the stronger it is; but with a cost in cutting performance. Talking about what exists today, there is no knife which sharpened at a 10 (or less) degrees angle can cut a can in a hurry and still be shaving sharp and have no kind of deformation (not even INFI). The thinner your knife and the sharper it is, the better it cuts. If the toughness, strength and deformation resistance can be maintained or increased while decreased thickness at the same time, then it's easy to imagine why you'd need a better knife than you already have. In conclusion, there is (and will always be) a need for better (at least for me).

I will always be dreaming at a needle thin tip and shaving blade edge lasting forever while doing anything with the knife....
