I think it's 26 in total on a .5" width blade...
It gives me the option to step up to 30 degrees...
Is 26 degrees too thin, should I go to 30?
I don't know. I'm sure the 26 is wicked sharp and would probably be ok if all you're cutting is tomatos and carrots. It will need to be resharpened often at that angle. It's a personal choice.
For my Sebs, I used the 19 (38) degree setting on a Gatco, and then do a micro bevel of 20 (40) on a Sharpmaker.
I use them every day for the usual stuff, wood, cardboard, plastic, food.
After the initial sharpening, I let it go to see how long the edge would last. I was amazed! After six weeks, it was still pretty sharp, but not like the original razor's edge. Now, I run it on the Sharpmaker once a week, about 20 strokes, and it's always like a razor. Awesome steel! When people complain about it's edge holding abilities, I just don't get it. What do you want? A knife you don't have to sharpen, ever!?
Anyways, my point is that the 26 will probably work just fine, though you might have to touch it up quite often.
Sorry, I'm wordy early in the day!
