Good report Leo, nice to catch up with you my friend! Hope you are doing well.
I haven’t tried convexing yet but so far my Gyutos, (chefs) knives hold up very well with an 11.5 to 12 deg. angle.
Of course my knives don’t get the rigors of outdoor use like yours! And I probably get some micro convexing from finishing with the polishing tape mounted to the leather strops.
But I will try it on my Spyderco ZDP189 Delica, which is my EDC, the next time it needs sharpening.
