How to change strong detent

[Leo3an]

Hi,

Im new here. I dont have many knives, and they are all pretty inexpensive. I have 12. Im not a huge knife guy, and i dont know the terms well. Sorry for long post.

I got a Ruike 108 a week ago, and the detent on it seems to be a problem for me. I have no problems with other flippers.

When I use the flipper, i have to push it hard. And when it opens, it snaps open very fast and the frame lock gets sticky.

I tried to loosen the pivot and it does not fix this. All it did was give blade play, snap open even faster, and/or blade touching the liner when closed... but still requiring same amount of force to flip open. So i think either detent ball too deep in detent hole, or framelock is pushing into tang harder than it should.

So i disassemble, maybe i can try to “bend” the frame lock backwards maybe... but the framelock has the useless “beta plus lock” thing attached with a free spinning screw on it, and I cant remove the beta lock. So I cant really change the pressure of frame lock onto blade.. also a bit rusty and many burrs inside the knife.

How do i fix this? Do i grind the detent ball or dremel the detent hole to be a bit softer? Im just about ready to just return this and not buy Ruike again. The quaility seems much inferior than the cheaper Ontario Rat 1 and 2. Sure they use nicer steel, but when I disassemble it, it just seems cheaper than it is. The cage ball bearing is cage in plastic, not steel. They balls ride on steel liners that seem not perfectly smooth, and some screws just free spin, and cant unscrew.

I maybe wrong but to me it feels like they went on a checklist of all the cool features like:
good steel? Check
ball bearings? Check
nice packaging.. check!
Cool looking??? Check
Low weight? Check
Ergonomics... well we cant really show ergonomics so forget it.
Now just put it together and sell it cheap. Dont care how it is inside as long as the features exist.

I much more like the the cheaper Ontario Rats because they are build well.. even though they look worse aesthtically, made with cheaper materials, with teflon+bronze washers and comes in a crappy box.

Sorry for long post. Very frustrated because i really wanted to like it because.. it was cheap and made with good stuff.. but disappoined when i disassemble the knife

Ah! Thank you.

Btw, i didnt know the cheap vs inexpensive wording difference. On this post.. when I said cheap, it meant “cheap pricing” or “inexpensive” not poor quality.

Ruike’s inside seems poor quality in craftmanship, with burrs, discoloration, harsh machining marks, and free spinning screws. Hence, in knife terms...Ruike 107 is not more inexpensive than Ontario Rats, but cheaper build than Ontario Rats.

In non-knife terms, i just mean.. Ontario Rat is cheaper but better.

I do not see anything on how to change detent strength. If anyone who knows how to change detent strength, i would very much appreciate it.

Sticky lock can usually be loosened by applying granite to the lock face - do it as many times as needed.

Try to put a drop of tuf glide into the detent hole to see if it helps open the knife easier.

Hi Sharp Edge! Thank you for your reply.

I should have mentioned. I already did try these things, they do not help.
1) lube detent path & hole
2) flip the knife many times
3) loosen pivot screw
4) graphite on lock + tang where they meet
5) sharpie on same place
6) lube ball bearings

When i flip the knife, my index finger gets red and soar. And blade flies out swinging like a knife sized baseball bat, and it hits hard... lock gets stuck.

Does the detent ball sit too deep in the detent hole? Otherwise, maybe it is just the lockbar has too strong tension.

If you bought it new and didn’t mess it up when you took it apart, return it. If you like the style, looks and it fits your hand, try another. If not, try something else.
Good luck!
Joe

Thank you.

- How do i change lockbar tension? I will try to figure out how to take out beta plus lock

- how do i know if ball sits too deep in hole?

Thanks!

When the blade is closed, try to see how much space exists between the blade and the lockbar in the detent ball area.

Can you take off that beta push lock so that you can bent the lockbar outward? That is how I normally reduce the lockbar tension but you will have to be very careful and do it gradually so that it does not introduce lock rock. That should also help reduce lock stick

If you don't like it, return it. Life's too short to own things you don't like.

He disassembled the knife - the option of returning it ended with that action...unless people are okay with buying knives, as new, that have been disassembled & returned. At this point, it's warranty time...which is less than convenient when it has to go back to China.

 

[Leo3an]

Thank you for the answers. I will return it.

I bought it from Amazon. When purchasing from Amazon, you can return it. No questions asked, for a full refund. If you are not satisfied with the product, you return, and because it is FBA, it gets thrown away, not resold.

Thanks

 

[Leo3an]

To clarify Amazon returns. As long as the item is defective and you did not cause the defect, you can return the majority part.

For example. I buy a knife from Amazon FBA, it has a minor scratch. I sand it, buff it, strip it.. and totally ruin it unusable. Then I contact Amazon and explain what I did, ask them to tell the seller to please QC. They say because i messed it up, they will give 80% refund... well, i wasnt even expecting refund since i messed it up, i was just letting them know. But they ask if the scratch was there for sure before i sanded it. Yes, thats why I sanded it. So they said that i just made defective item, just more defective.. so I am issed 100% refund.

The seller is notified, and seller is not allowed to sell returned items, unless i returned as “wrong product arrived”. But the seller has a choice to get the returned item for inspection and/or R&D for QC. Most times, seller ignores Amazon report on refund and the knife gets toss in the trash.

Please do not abuse this. But it is great for consumers. Bad for sellers.

Please don’t take this wrongly.
There have been many reports of people getting ‘new’ knives From Amazon that looked like they went through a rock tumbler. People have gotten clones when they ordered the real thing.
How??? Thieves will buy the real thing and return a clone.
If you return that knife, there is a good chance it will be sold again.

Hi Joe,

Yes, this is a problem. People need to be honest on “why” they are returning. When you return, there are options (not sure of exact wording)

-Did a wrong item arrive?
-Was this defective?
-Was this not to your satisfaction.

If wrong item:
This item gets re-organized and sold again. This is 100% refund, because it is not what you ordered. But people keep selecting this to return defects.

if defective:
No questions. Just thrown away, given 100% refund. Please select this if defective.

If not to your satisfaction:
80-90% refund depending on item category. Because that was not seller or Amazon fault. This one is resold again. This is not defective, just wrong size pants, ordered wrong color, basically buyer messed up the order.

So as long as you are honest about the real reason why you are returning it. There is no problem. But some people are lazy. They mark defective as wrong item... gets sold again.

Past the point of returns. Put it back together, sell it, gift it or use it. Nothing bugs me more than when I get a "new" knife that obviously took a stroll around the block in someones pocket (or disassembled).

 

[palonej]

Noooooooooooooooo!!!! PLEASE?????????

Next tell 'em in math why a convex is thinner than a flat grind!

Hey Leo!!
Your post states the was it is ‘supposed’ to be done.
Sadly, too many people abuse the generous return policy.

Why people keep saying not to return it??? Like I said, it will not be resold, when you mark as “defective” on FBA items.

Only when you return saying “wrong item” or “i ordered wrong thing”, is it re-sold again.

Amazon FBA doesnt care about sellers. They will throw away items marked defective, and seller eats the cost, they just want customers happy.

If NOT FBA, then it is sellers choice. Maybe seller gets a returned item and just resells it. Which is just horrible. FBA is fulfilled by amazon. Seller doesnt even get a choice. Seller sends bulk items to Amazon warehouse. Amazon just throws away defectives after asking seller if they want it (seller pays shipping to get the defective one)

 

[Leo3an]

Somehow people assume defective product returns are not 100% refunds. It is 100% refund.

So plz dont select stuff like “this isnt what i ordered”.... you get the same money back. Only difference is. Is it resold or tossed

Going to move the post that woke this thread to its own thread in the maintenance and tinkering forum. And am closing this thread.

Recommendations for an overly strong detent

So my Jose Pena Mula in Damasteel with red Fat Carbon inlay had a way too strong detent. I love the knife, so I followed the Neeves Knives and here. I disassembled it and took of the steel travel stop for the framelock off very carefully and slowly, which can be tricky. Be patience and wiggle...
