I love mine.
Though it is not a "stabbing" knife it is very good for filleting or trimming fat or cutting food etc. Really sharp.
You get the functionality of the standard knife, with less weight, a flexible blade and in a much sexier, lean package.
Here is a repost of it being used to trim the fat off a pork shoulder I barbecued a while back.
Short answer: Buy one!!!!!
Edit: they are a bit more expensive than the standard ones but they are available here. With Opinels I find that it is better to personally select your knife as the "feel" differs from one to the next (how hard it is to open or close etc.).
