Hi LLG. Jake from CanadianCuttingEdge did a review abot this knife too. And a lot of viewers have the same problem to open this knife. I also had this problem, but I found out, that the tip of thr middle-finger was applying pressure on the lock-bar (I´m right-handed). Now I position the fingertip on the clip, my ring-finger on the recess of the lock-bar and my thumb between the pin and the scale. Then push the thumb mainly to the side and only slightly forward - the blade always opens without any problem. Greetings from Germany. Hans
i have one and was very hard to open ,but after couple days no problem ,nice little knife i like , is well made in my opinion , take care all the best my friend ,
Mine was tight when I first opened it, but once it broke in and my thumb healed, haha, it opens great now. I think it just has to do with the small slim size and how close the stud is to the scales. All in all, a handsome edc knife. I enjoy mine.
I had the same issue with my 7010. I'm new at knife collecting so one of the first I got was the 7010. I about wore my thumb out trying to flick it open. Even developed a small callous! Then out of the blue I started flicking it open. Later I'd go back and I had the same problem again. Now like I said, I'm new at this so I figure I just need to practice with it. I'll figure it out.
I've had exactly the same problem with the grey version. I even chucked it in the drawer out of frustration. After using it again a few times it just decided to work. Very strange.
I had the same problem with a 710 and my land 7030 (or whatever the number was) It was a pain to open until it was broke in. I think the problem is the frame itself isn't completely even because if I completely disengage the lock and let it free fall it gets slowed down at certain parts of the swing.
I had exactly this issue with the 710, maybe I just suck at opening these with one hand too but I was wondering of it might not also be that it's very easy to slightly press down the frame lock when opening making it impossible to open it as you described and also atleast with the 710 you might actually press down the clip on it of you hold it like that aswell, or well I might just suck at this I think it's all of the above to some extent.
I had this problem with my 7056. The flipper worked perfectly, but if you used the thumb studs, it would lock up. I believe that the detent hole for the closed position allows the ball bearing to sit too deep. When lateral force is applied during opening with the thumb studs, it buries the bearing and locks the knife. The best ways I know of to prevent it is to let the hole get worn in, which may not happen quickly given it is harder steel. Or to radius the detent yourself.
Three things happen so it becomes easier: A. The copper washers in the pivot polish themselves from repeated use so they become slippery B. The oil they apply at the factory evenly distributes C. You come to learn, by trial and error, without consciously realizing it, the exact, very specific attack angle which works best.
Hi I got the exact same knife with wood scales ,its a great knife worth every penny . If it had an axis lock it would be better than the mini Griptilian .Of course the steel is not 154 cm , but soon the Chinese will start with their own powder metal technology . I think some of the Chinese knife companies are using American SV-30 , but you never know for sure ? Enlan /& bee have very good quality control as well as Sanrenmu, I have several of their knives as well as the 707, 704 & the 710 of their sister company .
After posting my original comment to this vid, I started playing with my 7073 a bunch and I wanted to add to my initial response… It's true that mine smoothed out and became much easier to flick open, however, the blade centering repeatedly goes off. I noticed that every time I tighten the pivot just enough to center the blade, it goes back to being very hard to open and not smooth at all. So basically, you have to choose between easy opening or blade centering. My concern is that the pivot repeatedly gets loose very quick and I don't want the blade to rub against the liner. I'm gonna put some thread lock in and see if it helps and possibly reverse the washers to opposite sides. Personal conclusion: This is a decent inexpensive and handsome edc knife to carry in your store, but maybe not as good as many many other ones you sell for the same money. But I can imagine some of your acid etching work would look pretty stellar on them.
Sanrenmu probably improved the quality on these knives. I got mine in a couple of weeks ago and it flicks perfectly right out of the package. Might even flick better then my 7010!
awesome knife, but same problem.. I just bought it and it's crazy difficult to open with my right hand. The weird thing is.. it's super easy to flick it with my left middlefinger.. ridiculously easy and it flicks super hard :), without any screw adjustment.
"till it hurt my thumb" try doing it with your nail, that's how i do it, works faster and more reliable for me too. Sanrenmu definitely makes some quality stuff.
I have such knife. I have the original one too - the CRKT drifter. I like this better than the original. The construction is better, the steel feels stronger and the fit and finish is superior to the original. I never had any problems with opening it - feels like any other thumb stud knife. Maybe you noticed a problem and you start thinking about it and it bugs you but for me it never existed.
They're good for new knife people on a budget; but their tempering is pretty bad so retention is far lower than what it could be, even though it's 8Cr13MoV
Lazy Lizard Gear Oh yes, I agree. I worded that wrong when I said "imitation". As you and a few other chinese budget knife enthusiasts have taught me, Sanrenmu makes many of the budget knives for American companies. At least, that's what we all theorize. Do we actually know whether it's ever really been confirmed though? Obviously, all signs point to yes, just never seen hard evidence. If not, than they make really excellent "brand -inspired" knives for a great price. And you've made an awesome business on them. Love your work, btw!
ChristopherRobin Canadian Cutting Edge has confirmed that Sanrenmu makes the Chinese made Spydercos and the Ruike knives (knife division of Fenix flashlights). That being said, it is also possible that the Sanrenmu branded knives are made by a different set of employees and different level of quality control.
