I ask this because it seems to be all over the place....more so on the Japanese knives. For a long time I was having issues getting a good edge just using the instructions for the Sharpmaker and a 40 degree setting. Until I learned the sharpie trick, I could never get a great edge. An example, my ZDP-189 is 40 degrees on one side and < 30 degrees on the other from the factory. Using the 40 degree holes on the Sharpmaker, one side will not hit the bevel at all....and I have to adjust to hit it.

Now my Golden knives are pretty spot on....My FRN Native and two Militaries are right at 40.....so is my Taiwan Techno and GB.
 
The edges are sharpened freehand by people on different parts of the world, its going to vary.

The diamond rods or a coarse stone for making bevel corrections will be needed if you want to fix these "issues".
 
I'm not sure; none (1 Taiwan, 2 USA, 1 Japan) of my Spydercos have symmetrical bevels. Although, my PM2 is pretty damn close to even.
 
I don't know if this helps or not, but the YouTube video where Sal demonstrated how to use the Triangle Sharpmaker, he suggests using the 30-degrees position.

At 8:57 minutes on YouTube video of 2 of 4, he recommends 40......30 as the back bevel.
 
I feel like they should include a special Spyderco sharpie with the Sharpmaker. It's so clutch to seeing what you are doing even with a loupe.

My bad. That's for the correction. It's been awhile since I watch it. I guess I should have recheck first. I don't l like incorrect information being spread.
 
I guess I was wrong. It is just a hair under a perfect thirty degrees. I noticed this now that I sharpened away just a bit of the factory grind. And put a 40 degree micro. What an edge Spyderco. I loved my ZT. But when I just made some guacamole dip with my wife. This Manix XL cut through the veggies like a razor. Even better than my kitchen knives. A true slicer with enough thickness to be tough as well. :) Happy Superbowl!

This.

Every knife I've ever sharpened (not just spyderco, all of them) on my lansky or edge pro were unequal from one side to the other. Some more than others but even the ones that *looked* good and even were off. But all of the spyderco's I've bought were pretty sharp out of the box. And were around 30-40 degrees inclusive.

Also, the sharpmaker is great for touch ups, but I wouldn't want to reprofile and or fix a factory edge with one.
