I *love* the delica/endura, though must confess I usually break off about half a millimeter of the tip pretty quickly.
I usually cite the Delica as the top of the price/performance ladder. Once you've spent $30 for your delica, I feel you're looking at diminishing returns. You can go buy a $60 knife, but you won't get twice the performance!
I also use the delica and endura as the "control" knives for all knife reviews I do. I feel any knife performance review must contain a comparison to a control knife. Knowing "it cuts 30 pieces of rope before it gets dull" is not interesting unless you know how other knives do on that same piece of rope. The delica/endura are great control knives because their performance is outstanding for their cost, but it is possible to get better cutting performance with some careful design. Still, the delica/endura will outcut many many more expensive knives.
Light, easy to open, solid cutting performance, ergonomic. They're awesome!
