Wow! It’s incredible to me (not surprising but incredible) that you guys can even do a fix like this. When you re-profile to this degree how do you do it? Do you grind the edge down by grinding the sides? Going back and forth (side to side) until you have taken off enough metal to get to your scribed marks. Or do you just grind down the old edge by grinding perpendicular to the edge? I presume you need to do all this metal removal before you even try to start grinding a new bevel. Hopefully that question makes sense. I don’t know how else to ask it
Great questions!
Repairs like this kinda pick up right at the tail-end of the knife making process. What I mean by this is, as an owner of a particular knife that you picked up in the retail setting, you really only need to maintain its sharpness because everything else (making a new knife) has been done for you. Now, this can be rather simple – Keep it sharp. Or, it can be rather complicated and inexhaustible – Welcome to the Wicked Edge Forum B)
Such repairs call for reprofiling the actual geometry of the knife itself while at the same time keeping in mind the geometry of the edge throughout the entire process.
In order to do repairs like the ones you see in the photos, typically we take some sort of an abrasive to the steel in a fashion that is perpendicular to the blade steel. Typically, this removes the material faster and leaves you with clean 90° angles where you’d expect them to be. Now, whether these abrasives are dealt with by hand or by machine, the fact remains they are still abrasives doing what abrasives do… Removing material from an object.
Once the overall blade geometry has been achieved through the use of abrasives such as sandpaper on a block, sheet of glass, or on a belt fed through a machine, we then move on to the geometry of the actual edge itself… This is really why YOU are here and participating as a member on this forum… That being said, please stay involved and you’ll learn a ton from guys like Josh, Dan, and many other awesome cutlery lovers :woohoo:
Hope this helps a little!
