Setting the detent on an horseman

[Therom]

Hello,

I have a horseman that has a very weak detent
The knife is new and I got it from a well known online shop that is reliable

I have the knife since a couple a week and it is still breaking in.
The lock was sticky at the beginning but is ow very smooth
But the detent worry me in closed position
I can flip the knife open with a firm wrist action
I never had this on any of my knives before
I tighten the pivot so the blade is secure but it seems it is more due to the tension of the pivot than to the detent ball engaging the blade

Have you already addressed this issue?
Is this something that can be adjusted?

Have you had it apart to inspect the detent ball & tab/spring? I would try inspecting it first - that may reveal what is going on and if it is a simple fix, or a call to EKI.
