Re: data so far have been helpful

Bill, it's not "whatever you choose to call the thing." There are big differences between western cap irons and eastern sub blades. For example, in better planes the sub blades are made to mate with a particular blade, thus in a particular placement relationship with each other. They are held in place with a small rod, a blade pin, that runs from side to side. There's usually a wooden landing supporting the bevel (bevel down, always). I don't know whether the sub blade's official job is chip breaking. And often it's not necessary or helpful to use a sub blade at all.

Tom?
