There is virtually no maintence with the umnumzaan. I have had mine since last summer and I use it everyday and it just seems to get smoother each and every day. I did not have the tool in the beginning. I took it apart and did a very thorough cleaning since I got it in a trade. I broke a tooth pick in half and used that for the pivot bushing. I did end up getting the umnumzaan tool from CRK as its much easier to us. The sebenza wrenches work for the two allen screws ( one rear and one clip ). You can tiea lanyard on like a sebenza or use the new lanyard barrel thing. Min has the one that falls out if the lanyard is not attached. I put a lanyard on it when I got it and it has been on there ever since. With the new perferated washer, I can see alot less taking apart and cleaning of the zaan compared to the sebenza. I really like the zaan as it has everything the sebenza has plus many updates Chris Reeve though were better. I am sure you will love it as much as I have. I have my pivot bushing set where it will rotate snuggly. If the knife is too tight or too loose, I rotate the pivot bushing and it basically re-adjusts the tension. Mines opens so fast, like an automatic, its that smooth. If I rotate the pivot bushing, it slows it down a smidgen. Mine has no blade play even when the blade opens like an auto. Money is tight now, so I got mine by trading a lik new strider sng. I could not be happier with the zaan, let us knwo how you like it when it arrives. ???
