    Hello all. I have a set of kitchen knives that have bevels as shown in this photo. It looks like the angles are the same on each side, but are offset from the blade centerline. I’m trying to decide between the WE130 and Gen 3 Pro.  Can they both sharpen this type of edge?  Is one better than the other?  My intuition tells me that angles will need to be adjusted on either side to compensate for the offset, but I don’t know for sure.  Alternatively, can the blade be offset slightly to center the apex of the blade?  Any insight from those in the know would be appreciated.

    If you are doing a 70:30 edge as shown in the drawing then both units are capable of that. The angles are identical on either side but the blade is intentionally sharpened so that the ratio of bevel sizes is 7:3. You simply need to spend more time working the side with the larger bevel.

    That said, if you are trying to do different angles on either side of the knife then the WE130 is the only way to go.

    Am I seeing this right?  Looks to me like the DPI are identical, it’s just that more material has been removed from one side.

    Yup, like Organic says.  Spend more time on the side with the wider bevel – for example, do seven strokes on one side and three on the other.  You’ll get approximately the 70/30 ratio you’re looking for.

    By the way, the narrow bevel should be on the side opposite of the hand you use to hold the knife.  For a right-handed user, the narrow bevel should be on the left side of the knife as you look down on it as you cut.  Put the narrow bevel on the right side as you look down on the blade in the vise.  Opposite for lefties.  The offset serves to make it easier to cut very thin slices if you’re holding the zucchini with your opposite hand.  Which is always.
