Sharpemaker - toothy edge & "move back the edge"

[dextersp1]

With the Spyderco Sharpemaker, how do I do the following:

1 - get a 'toothy' edge. I can get a polished edge but don't like it because it doesn't 'bite' the way I want it to.

2. move back the edge - or thin down the metal behind the edge.

I use a 40 degree back bevel on my knives.

I have the two normal rods that come with the Sharpemaker.

Please let me know which rod to use, flat or edge.

Thanks

My Sharpmaker came with 4 rods...what color are the ones you have?


Moving back the edge is not a string I am familiar with...generally Sharpmaker proponents want their edges ground at 30 inclusive, then they can "touch up" on the 40 degree setting to keep their knife sharp. Repeated "touchups" will result in a larger and larger 40 degree cutting bevel (and the 30 degree "back" bevel effectively shrinks as it is overtaken by the 40 degree edge bevel).

Sounds like you want to use the 30 degree setting with the corners of the coarsest rods you have available to "back bevel" the knife. If you continue until you restore the entire edge grind to a 30 degree inclusive, you will have reground the knife. After which you can simply "touch up" on the 40 degree setting....start out with the brown rods on the corners (assuming you have them) then progress to the flats, then to the white corners, then the flats. STOP at any step where you feel you have the coarseness in the edge you want.

Some folks go from the white rods to the brown rods again to gently add some "micro-serrations" to the polished edge. A few gentle strokes can do it.

I would get some rougher rods, there was a guy who just shoved a file in to the triangle slot. The brown stones are all you need, they are already very fine. I would avoid the white stones.

Did you rub the corners of the brown stones together? If not, do so, then just stop after sharpening on the brown stone corners. My Sharpmaker is over 10 years old, and the instruction video (VHS) showed doing this to roughen up the corners and speed up cutting. Sal also said just using them will do the same thing, but takes some time.
