Since the Micra is *still* in production (this year, it will be the longest running production Leatherman, beating out even the venerable original), they will most likely save time by sending you out a new one.
That is unless you send along with the warranty claim a note stating it is of sentimental value, in which case they will repair it.
I don't know what shipping to or from Istanbul is going to cost, so only you can decide if it it worth it.
Another thing to consider is, whether or not there is an official Leatherman licensed reseller franchise / authorized dealer (i forget what they actually call it) near you. They may have exclusive license to handle warranty claims in your country, and you may have to go through them. There are numerous threads about the varying quality of service in different countries, so you may want to scan the threads and find out how it is in Turkey.
I hope that helps.
