940 Question

Given that the 940 is not flat ground and not considered a slicer, will changing angle of the secondary bevel or adding a recurve help at all with slicing given the limitations of the 940's grind?

  The 940 has a flat ground blade..  Just FYI.  Changing the angle of the sharpened edge to something steeper will always improve slicing by making the edge initially sharper; however you may find that you sacrifice edge retention over time, and you'll also need to remove more material to get that edge steeper.

  Thanks for the quick response. Is the 940 considered flat ground but not a “full flat grind”? The terminology can be confusing for us non-knife makers.  What is the factory angle for the sharpened edge of the 940?

  Yes, that's correct.  A full flat grind runs off the spine of the knife, like the 15200.  The factory edge is ground by hand, so it does vary somewhat, but the target is 35 degrees inclusive.

  So, sharpening at 40 on the Srarpmaker you are spot on for maintaning the edge?

  That's a little high, but should be fine.
