Of couse we all want the best blade-steel possible, but there is alot more to cutting performance than just the type of steel used--there is also grind and geometry to consider.
IMO, the Buck 110 has an excellent blade grind and geometry, and it is a very efficient cutter.
The tip is not too strong, but that does not make it inferior since it is very useful for fine tip-work.
And 420HC is not a bad steel and it does most daily tasks with ease.
But just for us knife nuts Buck also has the 110 available in ATS-34 and BG-42.
And Cabela's has an exclusive Buck 110 with S30V for less than $70.00 dollars. And it comes with a very nice belt pouch.
I've never had a Buck 110 with a weak lock, ever.
They have all been every bit as strong as my Spyderco lockbacks.
And since they have a top-notch warranty department, if you did get one with a defective lock, all you need to do is mail it them and they will make it right for you.
I'll also give praise for the simple beauty of the Buck 110.
The brass and wood are simply beautiful, especially compared to black FRN and black G-10.
And speaking of the handle...the 110's handle is one of the most comfortable handles in the knife world.
I've cut for very long periods of time and never developed a hotspot or blister.
The handle does'nt even fatigue my hand very easily.
The only real problems with the 110 are three things IMO:
1. It is very heavy--but not much more heavy than a Spyderco Chinook or Manix.
2. It has no pocket-clip.
3. Although it is easy to open with one hand right now, a thumbstud would make it easier and more safe.
