Every once in a while I like to dig this thread up to see how my appreciation for my large 21 has(or hasn't) changed. I stand by everything I said in my last post(which was just over a year ago!).
I just got it back from Idaho where it had its first warranty work done. Apparently I pinched the washers which had made it impossible to put everything back together without either slight blade play or stiff action. Well as CRK typically does they went above and beyond. They reheat treated the lock face to prevent future lock wear. Unfortunately though, they had to re blast the slabs erasing almost year and a half worth of pocket wash on the titanium.
I'm so glad I bit the bullet and pulled the trigger back in August of '14. I don't ever see myself parting with this knife.
