James - most of my designs are influenced by Nature or Natural design. In Nature, there is rarely any "scrap" or "waste".
The line that I like to use for comparison; "The Goal...No more than necessary, no less than perfect". It is actually a very thin line. That is in all of my own designs.
The Tim Wegner design has a beautiful pattern. Originally, Tim wanted two liners and a 5/32 thick blade. The first prototype was deemed by Tim to be too heavy. So we started to refine.
If I can achieve strength without weight, I will go that direction every time. Unless weight is specifically required (Chopping wood for example).
But that is my own set of parameters. Each designer has their own set.
If appearance is a major issue, then a whole new set of parameters enters the equation. "I don't like the way single liners look" is a statement that I cannot argue against. Performance is yet another issue and one that is testable.
I am however very interessted in all of the opinions as you are. Thanx for the thread.
