| About
the SCReW Decision Tree The sheer inventiveness of corkscrew designers has posed many problems for those who aspire to a neat and tidy classification system. There are two principles at work in the SCReW system: 1. Any aspect of the
corkscrew that provides a mechanical advantage to removing the cork takes
precedence over those which do not, e.g. the lever action of a HOOTCH-OWL
takes precedence over Figural and Combination tool considerations – it
is coded as L. Rules have been devised to determine where "difficult-to-decide" examples are placed. But rules can become unwieldy for everyday use. From necessity was born the SCReW Decision Tree that you see below. Grab a corkscrew you can't quite figure out what it is and then follow the decision tree. Just ask the questions and answer Yes/No as you go. Do not skip or start part way down! The problem with not starting at the beginning is that you will miss a nuance and then come to the wrong conclusion - pieces that find their classes towards the top of the tree may well drop into a class later on if you skipped the place where it should have been identified.
