I've been giving my P'Kal a try at EDC use.
The new caged Ball-Bearing Lock seems to be more debrie resistant than the older version that the Dodo uses. Originally, the lock was mostly a two-fingered operation to close, but I am now able to disengage the lock with my thumb only.
Had to remove the 'wave' pin as it caused too many undesired openings. I carry IWB mostly, but at work I carry in the pocket.
Since you sharpen knives, I am sure you already noticed that the blade grind makes sharpening to a good edge easy, no need to reprofile to a large degree was required on my part.
Blade shape is an issue for EDC, but for many uses the 'hawkbill' works fine.
I haven't had any particular issues as to gripping. The handle does have the two finger grooves and, thankfully, the blade has no finger choil.
