I didn't take any offence by Elen, but we can certainly debate what constitutes precision work or not. Any Cal. raises a valid point as to whether the work is being done at the tip or towards that back edge of the blade. Work done with back part of the edge will likely suffer from a choil. As Fonly points out, precision work done with the tip can benefit from a choil, particularly so, on a longer blade. Then again, if you just don't like choils, then you probably will not use them and conclude that they are of no value....
I'm happy if you're not offended. The way I speak (or more precisely write in this case) seems to often annoy people, and that is one of my many personal flaws.

And since I blabber on so much, then I accidentally write at the same time as others and make myself a nice big mess of things.
Yes, we can certainly debate about the nature of precision work. The part about tipwork I find very interesting because I do a lot of it myself. On longer blades (such as a 6"+) I find a choil not only ok but actually a noticeable advantage to have, for previously mentioned reasons. On a large knife, I prefer to have a choil.
But for small knives with regard to tip work in particular, I wonder what the effect of a choil in such work really is. I assume that when one says that a choil may help precision work with the tip, one is referring to the way the choil can transfer your grip forwards, closer to the tip? If so, there is a small problem. A knife that does not have a choil or fingerguard will allow you to grip the handle right next to the cutting edge. If the blade (and the cutting edge) is 3" long, that means your grip is about 3" from the tip, right? Now, if you have a knife with a choil, that has a blade with 3" of cutting edge on it, what happens when you choke up on the choil? Well, your grip ends up 3" from the tip, correct? So, uh, how is this better than the situation with the choilless knife, since in both cases the grip is equally far from the tip? Of course, if one should grip the knife that does have a choil by the handle, then the tip would disappear to well over 3" away from the grip, and in this sense the choil would facilitate a better grip for tipwork. But compared to the choilless knife, the advantage seems not to be there.
Now, there may be something here that I am missing, although I cannot fathom what it could be. There is of course the fact that the choilless, guardless knife doesn't have a guard, and is less safe in stabs. But I'm not sure how much stabs we need in our knifework. I personally never need them, and when I want to use one regardless, I will just change grip and support my thumb or palm on the butt of the knife to stop the hand from sliding onto the edge.
But-but, I said I would shut up, and now I didn't shut up. So I'll try that again. Sorry guys
