0560 Blem with Weak Detent

This may sound like a silly question but are you using the right technique to flip it open?

Not drilled thru on mine. 561, blem, serial #2710.
 
Mine is SN 4825 and it is not drilled through either.

Rycen, could you please elaborate on the proper technique to flip it? I don't think I'm doing anything wrong but I guess it's possible. I'm left handed and rest my thumb very lightly on the lock bar when I open it. As far as the direction I'm pushing the flipper, imagine a line from the center of the pivot through the end of the flipper; I'm pressing perpendicular to that line. Thanks in advance.
 
I just checked my 0561 (SN 3288) and my 0550 (SN 0202) as well, neither of them are drilled through either. All three look pretty similar to the Oregon's picture. Oregon, how's the detent on yours?

On a side note, I'd like to thank you all again for your suggestions. It's incredible that a new guy can come on here, ask a question and get so many helpful responses in such a short time.
 
Compare the lockbar on these 2 knives. Can you guess which one has the weaker detent? If your lockbar doesn't lay flat, the detent hole is probably not wide enough. You could find someone with a drill press and high strength drill bits to drill your detent hole bigger. I need to do this to one of my sage 2's because the detent ball is worn a little causing the detent to be weak.

I couldn't be more tickled with this folder. It flips open a tiny bit easier now than on day one (bot weekend after Thanksgiving and EDC since then). No complaints. They put out 25 on Friday for people to buy and I bot mine Sunday PM and I had about 10 to choose from and I worked them all. This lovely and knowledgeable Kershaw female employee and I discussed my knife and its lettering defect and the 561s as a class. The annual sale is warm, friendly and big fun for folks in this neck of the woods. Cutlery everywhere being sold by the people that make it. I've held the bearing that fit into the pivots in my hand and gotten the back stories. Nothing replaces inspecting the knife before you buy it. This knife and the people that manufacture it makes me want more from Kershaw/ZT.

Here's a video to explain what I mean about the technique

Rycen, thanks for the video, that technique is different than what I was using and works much better with this knife. The way I was doing it didn't allow me to get enough force on the flipper before the detent let go. I guess I was more used to a smaller flipper like the Ripple where the blade rockets out regardless of technique due to its light weight; a knife this size requires a bit more focus on technique.

Update on my issues: Using the technique from the video helped me get the knife to flip more reliably but I still wasn't comfortable with the detent as weak as it was. I took the knife apart again and bent the lockbar to add some tension. I bent it in small increments until I had it to a point where the detent was a little stronger but the drag on the blade wasn't increased substantially. While I'd still like to see a little stronger detent it's now improved to the point that I'm comfortable with it. It's pretty comparable to the 0561 after its trips back to KAI. After all of this I'm happy with the knife. The 0561 is going in the safe as a spare and this one's going to get used, hopefully a lot.

Once again, thanks to all for the suggestions.
