Most knives have the capacity to perform many functions. Whether more than one of these functions is utilized is, of course, up to the user. It's also up to the user to determine what is the best grip for each of these functions. This is limited by what type of grips the knife design will allow, and safety. Considering each possible function, the way the user chooses to hold the knife for each function, and the possible types of grips the knife design will allow for each function, there can be many ways to hold a knife. While I certainly agree with you that a choil is not necessary on short blade knives, say under 3.5", I cannot agree with your generalizations about how knives are held, as if there are only one or a few functions a knife can perform and only one specific grip to be used for each function.
I'm not sure what you mean here. Certainly knives are intended to have many functions, if by function you mean working on different materials - on small knives, chopping and such are hardly intended functions. For the functions a small knife is intended to perform, there are of course a number of effective grips that can be used - but none of them that I know of would absolutely require a choil to perform, and most would be either less comfortable or simply much less efficient with a knife that has a choil on it. Now, if you were referring to knives that have guards, then certainly you will get no argument from me that the choil can allow for better grips (in terms of precision, not in terms of ergonomics, which will suffer in such use), because that's the way it is, and there's no way around it - if there's a guard in the way, then you can't get a good grip on the handle for highest precision tasks, and a choil will allow you to take your grip beyond the guard and right next to the cutting edge for the best precision. I'm not saying, at all, that choils are useless or a hindrance in
all knives. In fact, I'm saying they're quite useful in large, blade heavy knives, and also useful on smaller knives that have swordlike features such as guards and extended ricassos on them that prevent proper precision grips on the handle. And the other thing I'm saying is that on knives that have been designed from the ground up for precision work, not impact work or combat use, choils, ricassos and guards have absolutely no place in terms of performance and ergonomics - their only benefit is added safety, and that is only a benefit to those who need the added safety, even at the cost of performance and ergonomics. If guardless knives were so dangerous, Scandinavians would've slaughtered themselves into extinction already with their guardless, dangerous knives, but somehow, such a grim fate has been avoided.
In reality, there are some functions I can perform better using the choil and some I can perform better using the handle. If using a choil was "packed with a decrease in ergonomics" I certainly would not use it, as I am not an idiot. Having the option to use either the choil or handle makes a knife much more efficient and versatile.
I'm thinking you're referring to knives that have guards on them, here. If so, I agree - on such knives, choils can help performance in tasks that require precision for reasons previously mentioned. If you refer to knives that haven't got guards, large ricassos and such, then I strongly disagree, and would very much like to see even just one function (short of scraping a firesteel on the choil notch) that you could do better with such a knife if it had a choil on it. There are very few such functions, and in the majority are those functions that will suffer from the presence of a choil.
Actually, I'm guessing that you use a choil because you're smart - because in such knives that you have come to use, you have a finger guard preventing a handle grip right next to the cutting edge, and therefore using a choil will give you the higher precision that you want in some tasks, even if a choil certainly isn't as comfortable as a good handle would be to hold. There is such a thing as false versatility, though: something that appears more versatile by virtue of design, but in reality, makes many tasks more difficult, and few tasks easier than they would be otherwise. In my experience, a choil on small knives meant for precision work is exactly such a false versatility feature. Again, in larger knives or knives with sword features such as guards, sure, a choil provides much needed versatility! If you want, for example in carving wood with the tip of the knife, to move your grip closer to the tip of the blade, a choil helps in that, certainly, and for novice users, will be safer than a choilless knife in such work. On the other hand, novice users should probably not try that, or they're likely to get hurt. Further, if you want your grip as far forward as possible, then the choil will no longer help at all. And rest assured, you can move your grip far forward with a choilless knife. Here's an annoyingly small picture that presents a close-to-tip wood carving grip I lifted from somewhere. It's a grip that I've used a lot, that works quite well in fact, and while it looks a bit risky, it isn't, if you know how to do it.
Many of the best-designed and highest-quality fixed-blade knives I've seen and used have choils. I'd have to wonder why the makers and manufacturers of these knives go to the extra effort and expense of putting a choil on a blade if they weren't a desirable and useful feature.
Many of the highest-quality knives I've seen have had thick blade coatings on stainless steel blades. The coatings in fact decrease cutting performance a little, but the benefits are added protection from corrosion and a supposedly cool tactical look. This isn't a jab at tactical knives - I have a lot of coated blade type of knives myself, and on some, I really like to have a coating, especially if it will see saltware use. The point is, knifemakers are quite human and make compromises, and are likely to consider the needs of their target audience. If, for example, their target audience really feels that knives need a guard to be safe, then they will add guards to their knives. And if they're smart, at that point they'll realize their knife just lost some of the precision it could have had without the guard. And after
that point, a lot of them are going to slap a choil on the blade as a band-aid to improve precision again. It's a vicious circle. As I've said, choils are a useful feature on certain types of knife. My argument is, in a nutshell, that the types of knife that can make use of a choil are the types of knife one wouldn't want for precision work (and precision work is pretty much what I would use a small to medium knife for, since the axe or a larger chopping knife will handle all else): knives intended for combat use involving lots and lots of stabbing, or knives intended for users that are not yet confident that they won't cut themselves up with their knife (needless to say, the latter group isn't too likely to attempt anything that requires much precision or skill). If that sounded harsh, then it's probably because it was - but that's the way things are. All things, including choils, have positives to them, but it's quite another question whether the positives outweigh the negatives.
True.
Why not just leave it at this regarding choils?
It means nothing to me whether a person likes choils or not. That's an individual decision. But I don't like to see them put down. Some people who have never used choils and know nothing about them might read these posts and think they are useless or worse than useless, and never experiment to see if they are beneficial.
Because that would achieve nothing. Why shouldn't we, then, leave everything to
that, and never tell anyone what works and why? Instead, when someone asks us a question or a discussion arises, we could just always reply: "Experiment, and use what feels right for you." That in itself is good advice, but it teaches absolutely nothing to anyone. If someone asks us of knife steels, perhaps of the virtues of mystical Chinese "440 Series Stainless" as compared to S30V on a Spyderco, should we just tell them to "experiment and see what works" for them, instead of, say, pointing out the rather obvious performance differences between such steels? I think we can agree that this isn't the way we want to go. Why, then, should choils be any different? If we can "put down" certain Chinese made steels due to their rather abysmal performance, why can we not "put down" choils for their factual effects on performance in small knives?
I'm the fighting against windmills kind of silly guy. Always been, always will. I'm not trying to "put down" choils as entirely useless on all knives or label anyone who uses them anything, even if one may be inclined to interpret my words so. My intention isn't to offend at all, although some find that hard to believe. What I'm attempting to do is remind people of things they either had forgotten or never knew in the first place. I figure that many of us in this forum can agree that knives don't need huge serrations in the back and enormous "blood grooves" to do their tasks well. So, why do those features still exist in many knives, even though some rather smart people think they're less than essential, even counterproductive? Because it's either tradition, or because the target audience likes it. It's the same with choils. They're not there because they make knives better. They're there, because someone had the bright idea of putting a guard on a work knife, and then noticed it didn't exactly help precision.
