    I just received this knife yesterday from BladeHQ, and the detent is way too strong. At first I figured the pivot was too tight, but once the knife is open, it will fall shut under it’s own weight when I remove the lock bar. So the pivot is obviously not the issue.

    One of the reasons I got this knife was for the great action that all the reviewers claimed it has. However, it’s so tight now that I cannot deploy it one handed. Instead I must open it two handed like you would open a slipjoint, and even then it requires way more force than your typical slipjoint, to the point that the thumb studs dig into my fingers.

    I played with the knife for about a half hour last night, and just kept opening and closing it, and it did get a slight bit easier to open during that time, but it’s still a long ways from being able to open one handed.

    Will this break in over time or should I send it back? Or is there anything else I can do to adjust it without damaging it. I’ve never disassembled a knife, so that’s not really something I’m comfortable doing to my new $300 knife.

    Just return it. If you end up keeping it and then selling your gonna take a bad hit on the secondary market. Return and exchange or get something else.

    If ceramic detent ball I would not hold my breath of it getting much lighter any time too soon. That ball may never wear down. The detent being strong seems to be a combination of how high the ball sits and how deep the detent hole is cut. I have a 456 with a shallow detent hole and it is quite soft. Have ZT 0900 with barely any ball showing but the hole is deep and it is hard. But at least those are steel and might wear down over time, but ceramic is so much harder. My thoughts any way. Me, if way too hard for my liking, I would move it along or return. Life is too short for uncomfortable or irritating knife.

    I was looking at those. Too bad they’re so small or I’d consider getting one. Personally , I like a strong detent.

    I called BladeHQ and they told me it should loosen up over time. They said as long as I didn’t use the knife to cut anything, I can return it within 60 days. So I think I’ll just open and close it regularly for a couple of weeks and see if it loosens up. Otherwise I’ll send it back.

    It’s a shame because I love the design of the knife. It kind of reminds me of a small Medford, but at a much lower price point. The quality is definitely there.

    Well, I just sent it back. It never loosened up. I think I’m going to buy a Medford, just trying to decide which one. I don’t want something too huge, so I was thinking either a Praetorian Genesis, or maybe a 187F.

    I’m in the same boat I just got mine today and there’s no way I can even come close to opening it with one hand or use my thumb to flick it open. I watched a couple reviews and I was so excited about the action. I always wanted Adam a thumb stub with great action and I thought I had found one with this nice but I guess it wasn’t meant to be.

    The detent in mine is very strong and I love it. I can flick it all day

    If you like to tinker, you can chamfer the detent hole. Careful, it's a one-way street.

    you can put a tiny amount of diamond stropping paste on the detent hole with a toothpick and work the blade for a while only the initial opening movement to chamfer the detent hole, then when it gets softer clean all the paste residue off and add a small drop of oil on the detent hole
