If it ain't broke, don't fix it.
A lot of people have commented on this topic. Now, I'd like to put my 2 cents in. The Delica and Endura are most likely the first knifes of spyderco that longtime fans have bought. I remember someone giving my father an endura in the late eighties, and it saved his life. I have carried spyderco knives aboard every boat I've worked on, and thankfully, I've never needed to use one to save MY life, but its nice to know that its there.
The Endura is THE trademark knife of spyderco, and I see a lot of people wanting its aesthetics changed. Spyderco's "designed in the dark" philosopy seems to have worked thus far, never having been concerned about looks, rather functionality.
A broken tip on a knife that you work with is no big deal, really. Just take a file to it and sharpen it again. I know that the knives I've carried to work look uglier when they're retired, than when they start, and this only gives them character.
last summer '04, my girlfriend began to work on a charter/party deep sea fishing boat, and I knew right away, that the delica my brother bought in '95, and both he and I have carried at one time or another, was the right knife to send with her on the boat. it is the frn handle/clip, fully serrated delica, with a chipped tip, blunted serrations, and a razor sharp edge (thanks sharpmaker).
Sal, and spyderco guys, leave the delica and the endura be. Tweak them up perhaps, but don't drastically change them. then they wouldn't be delicas or enduras. Spyderco has a VAST array of different designs, but these two have been around for a while, tried and true.
again, my 2 cents
