Fear of missing a key
Apart from the fact that they are originally sold with treble hooks, the main reason why the vast majority of anglers are reluctant to equip their hard lures with single hooks is that they are afraid of missing bites.
This is a legitimate reason, all the more so with the impoverishment of many environments and the associated scarcity of bites. When the day's catch is only 2 or 3, you don't want to miss out!
The example of trout and tuna
Having said that, we can see from the practices of anglers that for certain species, notably trout and tuna, the use of single hooks on hard lures has become a habit, and the fear of missing previously mentioned has disappeared and has even been replaced by the conviction that treble hooks are less effective than their single-pointed counterparts.
It should also be remembered that with soft lures, the use of the single hook is commonplace and few anglers question its legitimacy.
Fewer dropouts
If you use single hooks consistently, you'll find that there are far fewer unhooks than with trebles, and that the hooks are just as effective.
The first reason is that single hooks offer a much wider opening for greater latitude, and the presence of a single point means that the fish's lips can be crossed in their entirety.
What's more, today it's customary to fit hooks with a braided loop instead of the original eyelet. These hooks, known as "assist hooks", ensure greater mobility and better suction, but also prevent the fish from leaning on the lure to unhook. In short, the hook is "uncoupled" from the body of the lure.
No kill
At a time when catch and release is being adopted by a large number of anglers, the use of single hooks helps to limit the injuries inflicted on fish by limiting the number of bites, of course, but also by preventing the points from getting stuck in the mesh of the landing net and injuring the fish as it struggles.
Angler safety
The use of single hooks is not limited to the effectiveness and safety of the fish, which are inevitably less injured, but they also ensure the safety of the angler by greatly limiting the possibility of pricking fingers...
Choosing the right size
When it comes to replacing treble hooks with single hooks, there's one thing in particular to bear in mind. Of course, you'll need to choose larger models to give you a wider opening, but you'll also need to pay particular attention to the weight of the hooks, i.e. the diameter of the iron, to keep the lure balanced. This is all the more true with suspending lures if you want to retain that special character.
Position them well
On a hard lure, you need to pay particular attention to the positioning of the single hooks. You'll need to take into account the orientation of the hook eye, as well as that of the lure (horizontal or vertical), which differs from one model to another. For example:
