A lot of people all over the Internet are complaining about the super strong detent! People are having a hard time opening it with one hand! That’s crazy!

DougFLA123Yeah, it is true, too hard. I use my thumb in downward motion and works fine. I suspect it is the rough edges on the flipper - they dig into your finger so I'll be grinding mine down and see if it makes a difference. Very awesome knife tho - wish the blade was 3.25 and the handle just a smidgen longer!

zipsurfI don’t own it yet but I do wish it was bigger. Silly question but...Is there an issue with your fingers pressing on the lockbar when you’re trying to flip it open? I have that issue with some of my thumb stud knives, where I can’t get my fingers to stop pressing on the lockbar when I’m trying to push the blade out. It doesn’t usually happen with flippers though.

DougFLA123Hey Doug, Oh man I was about to say "yes it is a silly question". lol However, I did a quick experiment and moved the middle finger from the position I would normally have it when flipping with index. I moved it specifically on the pocket clip instead of normally what would be the lockbar. Bammmm! Works like a charm! You seriously nailed the issue ha. Wow, the only bummer is it isn't a natural hand movement to do so it takes a little effort to shift the middle finger onto the pocket clip/ frame. The fact that the copper and finish is a bit slippery doesn't help either. Perhaps it is just the nature with the size of the knife and a slightly bigger one like the Kershaw G-10 version would fix this.

zipsurfVery nice! You would think designers would take something as basic as opening a knife into consideration when they put their ideas into practice. We shouldn’t have to hold a knife in an unusual or awkward position to be able to use it. Anyway, I’m glad I was able to help! 🤓

DougFLA123Yes, you would think so. The detent itself is perfect when compared to other knives. However because of the position of the flipper or the design of the lockbar there seems to be this problem. I love the knife actually, the fit and finish, the design and my 1st Kershaw/ZT collab yet even after learning this fact you pointed out, still there is an issue. Even with making an effort to re-position the fingers in a bit unnatural way and holding the knife differently (forget quick deploy like tactical) sometimes it flips good and other times is still really hard. I know copper is soft but not that soft.

DougFLA123It's true. And while the detent gets easier and the flipping gets snappier, the lockbar gets stiffier and harder and harder to close the knife with one hand.

DougFLA123Have an update.....I was playing around with the knife yesterday and ended up taking it mostly apart. I re-lubed the bearings and put back together without the pocket clip. Woah, now it doesn't really flip at all and the detent is incredibly weak, almost non-existent. I read the review above and haven't tried with the pocket clip as love the feel of knives pocketclipless. The lockbar barely locks up now like 1/16 yet still solid but perhaps the caged bearings on the backside got mis-aligned and is the reason why the knife now won't lock-up with even 1/8 inch of lockbar to blade. I'm debating whether or not to fix at all as even though it doesn't flip, it opens like a slipjoint one-hand with some light pressure on the blade groove. Much, much easier to use, however with the detent so week it greatly increases the chances of the blade opening in pocket. Other than that, really love this knife, design, and copper/D2 version. Did I mention I'm a sucker for a good stonewash? ;)

zipsurfI don’t think you mentioned that thing about the stonewash! : ) A weak detent is a real pet peeve of mine. It sounds like the detent ball is barely in the hole. If it were me, I think I would dis-assemble and re-assemble it and see if things lined up better. If they didn’t align better I would return it to Massdrop and wait for a replacement. The only problem is when will they be getting these in again. There are a lot of things to like about this knife!

DougFLA123Well said Doug. Normally a weak detent is almost a deal-breaker for me too. However, incredibly my mindset has shift some since experiencing the way the knife first arrived. The only way to get the blade open was to use a lot of pressure via thumb in downward stroke or testing your strength with the pointer finger and just the right hand position. It became uncomfortable and tiresome quickly. Now amazingly, even if the one caged bearings is off a bit or misaligned the crazy thing is there is no blade play or wiggle, when closed it lines up centered OK/good, and there is still just enough detent to keep the blade in close position when trying to fling it outward just by inertia/mommentum. So the trade-offs are not really an effective flipper but now it opens one-handed easy with some light pressure on blade (either hand) and makes for a much more enjoyable experience. The negative is the lockup is too early (almost dangerous), the detent weak, and it doesn't flip more than halfway open. Yet I'm more happy with it now than when I received, not sure I want to mess with it! lol The knife itself is a work of beauty with the full stonewash copper scales and D2 steel. The ergos are fantastic and really loving this knife despite the negatives to the point where I would buy a second especially if they are limited edition. For the price it is great if you are a copper guy. Wish they offered in brass too.

zipsurfThat’s great that you’ve made it work for you! Not only is the copper really unique and cool, but the stonewash is really nice too!

DougFLA123Thanks! Yeah you were right about the stonewash on copper - wow never thought about that combination as never seen anyone do it but looks so rich and hides scratches. I thought there was nothing worse than a near-zero detent but not being able to open a knife (especially a flipper) is even worse. Another update! : Unfortunately I dropped the knife from a height of about 4ft. onto hard slate. Yikes! The good thing is not a scratch, thanks to the stonewash, the bad though is it knocked the pivot, blade, washers, and bearings some to make the blade now touching the front scale when closed and not even locking when open. ugh. So I disassembled the upper half, took it apart and put back together again making sure nothing was pinched. Amazingly it is back just as before. Really loving the middle-finger on the blade flick-from-the-back opening and just enough detent to provide some assurance the blade won't open with a blow of air. It boggles the mind how I cannot seem to get the knife back to the really-hard opening situation however I did grind down some of the aggressiveness on the flipper tab itself. Perhaps the grinding changed the balance or alignment of the blade? A bit perplexed but much happier.

DougFLA123I am reading thru your comments trying to find the message that you got from WE. I have experienced this issue with a couple of my flippers. I can't recall which ones, tho. On one, if I use my middle finger, the knife pops right open.

14themoneyI have contacted WE Knife Co a couple of times. One of my questions was...Do you guys have replacement parts for Massdrop x Ferrum Forge x WE collaborations...like for the Dao, the Buc, the Crux, etc? Their response was...No, please contact Massdrop Support. Is that the message you’re asking about?

14themoneyHere’s a link to CRKT’s parts request... https://www.crkt.com/parts-request/ and a phone number 1-800-891-3100. I’ve never dealt with CRKT but I’ve gotten free pocket clips from both Zero Tolerance (Kai USA) and Benchmade, screws from Schrade (Taylor Brands) , cleaning clothes from Real Steel knives, one of the guys on this website got pivot bearings from Bestech Knives, etc, etc. I guess what I’m trying to say is call them, write them, you never know. Alot of these knife companies have incredible customer service and really aim to please! They just might send you the exact screws that you’re looking for!

zipsurfSomeone. Ay have said this already but one of the flaws with this knife is that the screws for the pocket clip also hold the sub frame lock bar in location. They actually have 4 screws holding it.... 2 under the clip and the 2 pocket clip screws and its a bear to get right once you take it apart. At this point my fingers are sore and I can't seem at actuate the lock bar with my thumb anymore.

Enviroman@Enviroman. Indeed, however, after taking mine apart 5+ times I found the sweet spot. The perfect spot where it is centered and aligned put back together but allows the user/owner to flip 4 different ways. I'm absolutely loving mine now. 10 times way better when able to flip easy and excited to buy another when they come back in stock. You are correct on the 4 screws and after a lot of trial and error I found the perfect combination of tightness and looseness for those and the rest of the screws on the knife. When adjusted this way in conjunction it is the perfect combination to knifaholic bliss :) If you would like to send me your knife I can adjust if for you for a very small fee and you will be very well pleased.
