I am falling more and more in love with mine each day I carry it. Mine started performing like a $600 custom after a couple weeks of break in.
I was late to the show on this knife. Because I have never owned a ZT, I didn't pay any attention to posts about them.
However, at the very end of November this knife caught my attention when I was told about it by a friend. I really liked this knife from when I first saw a picture of it and luckily had one in my possession 5 days later.. bought off the Exchange here on BF.
I liked it even better when I held it and saw the excellent fit & finish. Due to an illness and other things I did not have time to use it much though until around he first of the year.
I started to read how people were saying they were as "
smooth as butter" after breaking in,
etc.
etc., and such as the quote above also.
Just to be honest, I though those posters were "
full of it".
So I started opening and closing mine while watching TV.. after a few days of this I realized that every word was true.

This thing became one of the smoothest operating knives I own...
bar none.
I thought it might be a fluke so I broke out another one I had acquired since getting the first one. The same results..... :thumbup:
This
ZT/H O551 is one heck of a knife IMO!!
Hats off to a job well done
ZT. :thumbup:
