Question on knife patterns

[Old Hunter]

I've always considered a Whittler to be a knife with 3 blades, with the large blade on 1 end, and the 2 smaller blades on the opposite end, and when all blades are closed the large blade sits down between the 2 smaller blades. Usually this style would also be a split-spring whittler, unless the knife has 3 backsprings.

Rookie, I have understood exactly the same thing; there are several ways to configure the back springs, but the blade positions determine that it is a whittler. OH
