Hmmm. Not sure. Was it ego that created the motor car after thousands of years of using the horse? Or ego which discovered monumental advances in medicine? The advances in knife design and metallurgy over the past century is incredible also and cannot be denied regardless of our own traditional preferences on this forum. I'd assume that the opposite to your statement in fact (knife regardless). The ego which holds back progress, by refusing to believe that improvements are necessary or even possible, by demanding unthinking obedience to the party line of whichever discipline or 'what everyone knows to be true', or the mindset that cannot see outside it's own specific requirements - that is the most dangerous ego of all. I haven't seen the new Opinel design and can't have an opinion over it but the theory that is is 'perfect' and cannot be improved on principle, just because it's been made a certain way for decades, is rather short sighted methinks. Personally I would like a slight knurling on the locking ring for better rotational grip with wet hands for example.
