In the past 25 years I have seen quite a few knife designs.
For some reason it is forever a temptation to most to over-complicate the simple.
Knives, when it comes right down to it should cut and anything that get in the way of that just doesn't belong.
I have seen knives so over-designed to do so many things(supposedly) that actual cutting is no longer the primary focus.
The handle is important because it is the user interface, and it is a common place to over-design as well.
The knife that was originally posted I can see no useful function for, it puts the hand in an awkward position for board cutting.
You want an example of a good useful knife, take a look at the machete, simple clean lines and it does what it is supposed to-cut.
