Here's a gear grinder for ya...
You just layed the most dead center, even from tip to choil grind on a blade, with uniform .015" flat right down the center, with mirror image radiused plunges...I mean, they're going to display this under one of those collimator things at the Smithsonian cuz it's so dead perfect and Blade Magazine is sending a guy out to document the first perfect free hand grinded blade in the history of mankind.
Then you roll it over and a train wreck of metal crafting hits you in that tender spot between your nose and upper lip and you see that you've ground the distal taper about 70/30 cuz you was so focused on getting that perfect centered edge...and now you gotta drop back to 120 and straighten it up without changing the centerline of the edge...
