ZT 0450 factory edge angle?

[manowar669]

Have a 450, before I bother to reprofile and sharpen, does anybody know the factory edge angle?

From the zt website.
TO WHAT ANGLE SHOULD I SHARPEN MY ZT BLADE?
Zero Tolerance blades are sharpened to angles of between 20° and 22°.

That's per side, not included?

It's per side. I usually reprofile my ZT knives to 18° per side.

Thanks. I usually reprofile all my knives sub 30 included, then maintain with a sharpmaker at 30. TheZT is new to me, so just checking before I undertake another reprofiling.
