amazon.com G10 Speed Bump

[bocephus21]

Hi all,
I, like the rest of us Kershaw junkies, bought a few G10 Speed-Bumps. However, I was reading reviews on it and came across this one:

"I purchased 2 of these from amazon because the deal was "too good to be true" however after having them for a month or so the torsion bar broke in one of them so I requested more from the factory which were sent. The bars received were the wrong design for this knife but they will work in the other speed bumps I suppose. After speaking with Kershaw it seems that the design changed at some point in the development of this knife and the first design for the torsion bar was altered and the scale was machined differently leading to an incompatibility between the two different designs. The bottom line is that if the torsion bar breaks (which it is likely to do at some point in your lifetime warranty) you will not be able to get a replacement and with the design of the knife as it is with a broken torsion bar this knife would definitely classify as a "gravity knife" leading to possible legal troubles."

Is it true that the torsion bars are different and thus irreplaceable?

Thanks,
Jake

I have to get in touch with a live body at Kershaw over the same issue.
I was sent replacement torsion bars via e-mail contact on 2 separate occasions....both bars of the same design and neither obviously fit.
However, I'm not overly upset by this as I find I actually prefer the action of the knife without the tension the bar provides.
I simply tightened the pivot screw (and the pocket clip screws to maintain blade-centering) to keep enough
pressure on the blade to keep it from literally falling out of the handle and give it a wrist-flick to open.
Works for me.

Maybe the torsion bars can be cut to size?

That's my next thought, too.

That's quite worrisome. It seems like it wouldn't be that hard to make a few torsion bars...

Well, from what I understand, the G10's built from the leftovers of a discontinued model...... hence the attractive price.
I believe I've also heard Thomas W. say that they don't keep 'spare' parts around...... knives are built in production runs without an emphasis on repair pieces.
I'm not complaining, it's a great knife for the price. Besides, most Kershaws function just fine w/ or w/o the torsion bar.

Guys -

Here's the scoop on the new Amazon Speed Bumps - we changed the design to use a newer style of torsion bar - it is a normal stocked part, and we have lots of them. The warrantee department probably got a little confused because it is unusual for us to make this kind of a change to an older discontinued model - I will discuss this with them on Monday. If you have any trouble, please send me an e-mail and I will get you sorted out.

We generally have spare parts around until a knife has been discontinued for several years - it depends on the knife. Our warrantee department will take care of you.

Bocephus - can you point me to the review that you quoted? I would like to email the individual in question to hep him get his knife fixed.

Thanks for sorting that out, Jim, it's appreciated.
Question : how would one go about having the stud-lock mechanism repaired should it ever fail.
Do parts exist for that?

Does that mean that people were being sent Spec Bump torsion bars? I have one, so it looks like I should get a few spares before they run out...

Just in case Bocephus missed your request, I PM'd you the info.

I had bought one from Amazon also, so I followed the info.

So nice to see this level of care from you and Kershaw. :thumbup:

I know it may be a tad late to key in, but Needs Work and Blur torsion bars work fine in these. And I've never seen a stud lock fail, 2 friends of mine bought the original Speed and Spec bumps when they came out and they still carry them to this day. As the knife wears in the lock becomes stronger like a framelock does.

Alann - Thank you. I am looking into commenting on the Amazon review - Amazon is requiring a few odd things (credit card info) so I am looking for a simpler way to leave a comment.

This could have happened to a few people, but I talked with the head of the warrantee department today, and they are aware of the correct torsion bars for the new Amazon G-10 and aluminum Speed Bumps. Anyone who has trouble with one should have no problems getting replacement parts.

Turk - Just an FYI - The Needs Work, the Blur, and the original Spec and Speed Bumps each had torsions bars that were unique to them. There may be some degree of interchangability, but I would not recommmend it. Finally, the knives we are discussing in this thread Amazon G-10 and Aluminum Speed Bumps) use a different style of torsion bar than the original Spec and Speed bumps. This means that the torsion bars you mentioned (Blur and Needs Work) will not work in them. Thanks!

Your welcome.

Wasn't aware they required CC info to leave comments.
Guess thats their way to cut down on junk comments and sort of restrict it to their actual customers.
On the plus side, you can pretty much trust Amazon with your info. I don't like giving my CC info online either, but Amazon seems pretty safe. Been buying from them for years with no problems.
