I have been carrying my 0562CF and am in love. I have the elmax version too, and I plan to buy another CF version as soon as I can. I dont normally buy multiples of the same knife but Its as perfect as I have found for me yet. I noticed I have a lower serial number and I also have a feeling the M390 version will be discontinued sooner than later.. My serial number is 0052. Is this considered a low serial number? I know its the lowest of all my ZT knives. I don't expect it to be worth a ton or anything, but I'm also wondering what you all would think. Something is telling to put it before I scratch it up...
