"Buck Knives....oh how plebian!"
Oh my!  I do apologize so fervently for bring up the name of such a common manufacturer !  

 All I know is that the Buck 105 I purchased in 1972 still works today, although it is on its second sheath.  I have had it almost as long as another good one, a Mora dating from 1973 [Ooops!  Did I just introduce another plebian brand?  Whatever is the matter with me]
Seriously, they are both still slicing away, good as ever.  Of course, I have had to sharpen them both from time to time.
I am not about to spend more than $50 for a knife, unless there is a substantial justification (and there usually isn't).
