Currently FRN is the only handle option available. They made a metal handled one in the past, called "Tufram". I've owned a Serrated Tufram model for the last 5 months, and find it gets more use than the Delica.
It's size makes it seem like less of a knife, but it's the perfect size for most tasks.
My opinion on the use of this little workhorse can be found easily on both spyderco forums.
Now we just need a 4" version of this for utility, and that will be the perfect workhorse. Just double the stats, nothing fancy...
