For most people, no. A karambit's curved hawkbill blade excels at pulling cuts through rope, cordage and webbing, and it is poor at almost everything else an everyday knife does: no push cuts, no board work, and a point that is hard to place. It is a specialist, not a generalist.
The inward curve hooks material and draws it into the sharpest part of the edge, so rope, cord, webbing and strapping cut extremely well. Roofers, gardeners and utility workers use hawkbill blades for exactly that.
The finger ring gives strong retention, which is genuinely useful in wet or gloved conditions.
Push cuts, spreading, board work, and precise piercing. The point faces down and away from your line of sight, which makes fine work awkward.
Sharpening also needs a rod, because a flat stone cannot reach inside the curve. See sharpening a curved blade.
Somebody whose cutting is overwhelmingly cordage and material, and who owns a rod to sharpen it. For general everyday carry a drop point folder does far more.
Note that a karambit is a knife design and a hawkbill is a blade shape. Many hawkbills are not karambits.
