It may be somewhat Whittler-esque, there's no way to tell without a profile view with the blades exposed. One thing it's not, however, is a 'Splitback'. A Splitback spring is a one-piece spring that - get this - is split down the middle. The split ends spring the minor blades, and the joined end springs the master blades. You often see Whittlers with two backsprings, the ends on one end spring the minor blades, and the paired ends at the other end spring the master blade.
If it has three backsprings it's not a Whittler. It's a weird pen knife.
What you're up against is that Rough Ryder knives are poor imitations of traditional patterns. They may be a good value, but you can't really learn nomenclature by studying them.
How to learn? I learned from Levine's Guide and by handling thousands of knives. I spent thirty seconds browsing the web and didn't find anything I liked, mostly because I won't watch a thirty minute video to glean the same inforation that I could from thirty seconds of reading.
Yes, I'm that old.
