Edge Pro and Sage 2.

[Joe_Karp]

My Sage 2 isn't ready for a full sharpen just yet, the 1200 grit EP ceramic rod works well for a quick touchup. But when it's time what do you guys use for the angle/setting?

I read it's 30 inclusive, but others say to set the table to 21 degrees for a better edge.

What's your say on this?

I think the most widely accepted geometry for edges is 30 degrees inclusive for the primary bevel and then a microbevel of around 40degrees inclusive. Remember that your Sage has a roughly 3 degree per side flat grind, so your edge pro setting will be around 18 and 23.

Edge bevel angle is a trade-off between sharpness and durability. A narrower angle will be sharper, but will be more prone to damage. Higher quality steels are more able to hold a narrow angle with sustained performance. There are guys on here that have ZDP Stretches and run their primary bevel at around 20 degrees inclusive. Do that on a AUS6 or 8CR13MOV however and you'll likely roll the edge before the end of the day.

You should be good with your settings, but in my experience, you can go a little narrower with S30V and still be fine.

Let us know how it works out for you.

For all the super steels i.e. vg10 and above, I always do 20° edge with 30° microbevel and it works fine. I don't hack stuff with my folders thou so your result may vary.

The thinnest I have taken any of the Spyderco use super steels (ZDP189, CPM S90V, CPM M4, etc) is 30 degrees inclusive. I primarily use the Sharpmaker so that is the thinnest angle that is easy to create. :) They have held up very well at that geometry.

I use 24/30 on my VG10 knives. I cut branches on my yard, cardboard, brown packing tape. No problem so far. S30V should hold the edge even better. IMHO to use more obtuse angles, if you have capability to put more acute on the high-end steel, just waste of steel potential. Harder steels made for better geometry. So let’s take advantage of it.
