This is a popular and well liked knife in the knife community. It's small, light weight, cheap, well made and reasonable materials. There are many videos of these on youtube. I like it. I would like to point out something that other reviewers seem to have missed though - the thumb stud. It is close to the blade pivot point - essentially this means it is geared pretty high if you consider lever length. That's OK, so long as you know - this blade flies out like an auto; there's no slow rolling it open. Because of this, it probably isn't the best choice for someone who is new to thumb deployment. All my other thumb stud knives I can easily slow roll open. After a bit of playing I'm getting better at opening this one - so a bit of practice and it's all good, especially if it is a regular user. My particular knife has a strong detent which takes a bit more technique on my part. I won't weaken the detent; I'd rather work around the knife and don't want to cause metal fatigue or overdo the weakening which could make it unsafe. Also take note: the g10 variants use 12C27 blade steel whereas the micarta versions use AR-RPM9 steel which is supposedly better (a powdered steel). I wasn't aware of this and thought they were all AR-RPM9 - those micarta / AR-RPM9 knives do cost more though.

Actually I just found a video where the dude found what I found, although he does dramatise a bit. He also explains it as "angle", which is kind of true but it is because of where the thumb stud is locatied - close to the pivot. It is as though it has been designed to be a fast opener. Also, he whinges about the cut out for the thumb stud - this is fine, not a problem at all; he has misdiagnosed that too. Detent and location of thumb stud are the issues here - this could be good or bad, depending on what you value. I think the hard detent is good (safe) I have adapted to that, just as he has. After sufficient practice (10mins?) I don't have a sore thumb.

Dont compare it to D2
Unless your comparing it to NQR D2 ( my 2c )
12c27n Is a step up from CrMov / AUS8 / 420 / 440 / most of the time ... ( Those nasty Variables )
But if poorly made , it can be terrible .

Do you mean AR-RPM9? That is often compared to D2. I don't think anyone compares 12C27N to D2 - they are quite different. I would have preferred AR-RPM9 to 12C27N. Although I also prefer G10 over micarta - I can't have both with this knife it seems.

Is it ? I have no exp with that steel ..... ( I was talking 12c27n - which is often disappointing rather than impressive ) I have a fair amount of 12c27n .
