umnumzaan thumb stud came off

How was no-one killed in that twisted hunk of burned metal.The warriors inside must be tuff as nails! This is the first we've seem on the forum of an UM thumbstud failure, lets get the whole story from Chris' camp. The 2 pieces have to go together somehow. I'll bet the shear strength is off the charts for the thumb stud .Thanks for your service, and humility! Bart1
 
wow, glad you made it out okay. As for your knife im sure CR will take care of you. I must admit i am dissapointed to see that happen especially since that is the lockbar. I think ill stick with a sebenza=P
 
Thank you for your service!! I am glad that you and the rest of the guys are OK. God bless you. THANK YOU for your service.

I am sure that CRK WILL take care of you. I am sure that they are going to be surprised that a thumb stud came off.
 
Wow, just wow. Puts my complaining about getting up early for international conference calls into perspective. Thanks for what you do and glad to hear you are ok. I too am sure CRK will take care of you, I wonder how this will be resolved.
 
We have been in direct contact with Joe – we only received his email this morning - and have given him some help on a short term repair, with the request that he return the knife to us for permanent repair once he is stateside again.

His knife is an early Umnumzaan. As can happen with a brand new product, we experienced some unexpected issues where parts did not work as intended. We have remade the relevant fixtures and have taken the additional precaution of redesigning the thumblug into one solid press-through piece.

That these early Umnumzaans had some problems does not mean they are inferior in any way, and we have taken care of the few that have had issues. Please remember that the Sebenza has had 20 years of development – a brand new concept sometimes takes a while to fully develop.

I carry an early style Umnumzaan every day. Last weekend one thumb lug fell out – because I had been wrist flicking, prompted by the thread concerning lock abuse. I re-set the lug with some loctite and have had no problems. I test and carry all my knives so I know what works and what does not.

One thing I do ask of all our customers: come to us first, let us take care of the situation and then post on the forums, not the other way around. This will preclude much of the accusation, extrapolation and general mis-information that seems to come into some of these threads. We ask this not to hide any problems – if there are issues, they need to be discussed – but to get correct information published.

Which year did the new blade-stop start? Mine was made June 25, 2009.
 
Thanks for updating us Chris :thumbup:

I can sleep easy again knowing my June 09 Umnumzaan has a solid bar in it :cool:
 
I have spoken with Chris on this subject in depth several months ago and again today and let me assure you folks that Chris Reeve is one of the most stand up guys i have ever spoken with.

There is NO need to worry....as CRK stands behind there knives 100% just as they always have.

Use your knives as they are intended and if you ever have an issue, just send it in for repair...it's that simple.

Chris Reeve Knives ROCK !!

The choil on the knife posted is much more shallow than on my new Umnumzaan, is this an easy way to tell if it is an early model?
I too would like to know the date when they were changed to a solid thumb stud.
 
Glad you are alright Joe, the photos really tell a story and definitely have an impact on us civilians even if you think it's just another day.

Stay safe mate.

Getting the knife fixed was never going to be a problem

first, i see no false accusations in this thread.

basically everybody agreed that "CRK will make it right"...and you are. so you should be very proud of the good reputation you and your company have established.

second, there is absolutely no way for us to know that these press-fit thumb studs were essentially a prototype, of limited release. consequently, it is important that all of us who own (or MAY own) this knife are aware of potential issues. it's a reasonable piece of information to disseminate since some us could find ourselves in the proverbial (or literal!) war zone, and need a knife that they can rely upon 100%.

i think that everybody involved here has come out for the better, and i don't feel that the reputation of CRK has suffered.

it's my hope that end users continue to inform each other (and the maker) of potential problems. it's the right thing to do.
 
Wow! Glad you are still with us! In this case, it is nice to hear about the one that got away.

Interesting timing on this thread. I removed my thumbstuds a few days ago. From first hand experience, I would say that most will not have anything to worry about as far as retention. Let's just say that the studs put up a great fight.

I personally removed mine to modify them for my own personal tastes. The new ones I made today are made from Ti and are a bit longer. If I think about it, I will post pics later in a separate thread.

Anyway, back to the regularly scheduled thread.

I think that worrying about something that may or may not happen is pointless. As I stated earlier, mine were not going to come out without significant force. IF and when it does happen, Chris and the team will take care of it as per their usual customer service!
 
I got an email from CRK today.They said some loctite should do it just fine and they explained the older thumbstud thing. I'm glad it's a solid now and hopefully that's what my zaan gets when I send it in when I get back I did call then send an email to them first before I posted about it. But I'm not sure about the time difference and I think it may have been after hours. Either way they got back to me within 48 hours which is more than acceptable. I'll find some mechanics and score some loctite. I thought about just putting it away and carrying something else but that wouldn't make much sense. I'm done not using my "high dollar" knives like having a vette and never driving it well I'm gonna "drive it till the wheels fall off" so to speak. Then here in a few months I'll send it in for the spa treatment and a new thumbstud. I'm confident that when I need it for something besides mres and 550 cord I'll be glad that's the knife I'm carrying and if something happens to it I'm confident CRK will handle it appropriatly. Like I said before this wasn't suppossed to be a "drama" thread just informational. I know I learned alot about my knife and glad that I did. Thanks alot for the support guys I relayed it to all my soldiers

Are you a soldier ? you speak of a "war zone"....I served and any folder i carried was not something i would bet my life on unless it was to dull to open MRE's.

A large fixed blade may be better suited for the keyboard commando.

BTW..Chris did not ask that people not speak of issue's.

These are just my opinions.

the point is that a $400 knife should be able to stay functional and in one piece under most circumstances--high tech a knife is not.

and thank you for your service
