Andy,
Spot on! An excellent and succinct summation
And you've discerned the "why" in my preference for wharncliff geometry. With that handle to blade edge the knife can be used effectively for both the tip pressure cuts as well as full slicing or push cuts. Hence my belief that having the handle too close to parallel with the blade's edge sacrifices a portion of a wharncliff's utility.
All that said, there can be no question, from your preference for tip use, that Ray Laconico's stout blade design featuring the less severe tip taper for additional tip strength makes for an outstanding tool in your hands! Its great when a tool exhibits design features that directly support the techniques of the user.
