Well I have been carrying my Adira daily for about seven months now, using it for everything from opening letters to chopping vines. I do a lot of hiking and used to always carry a fixed blade for trail maintenance, etc. With the Adira I really don't need the fixed blade - it does it all. I usually touch up my knives occasionally with a ceramic rod, but with my Adira being my first Magnacut blade I have let it go just to see how long it will hold an edge. So far, after some pretty tough use it is still paper cutting sharp! I am impressed with this knife!
