“Sharp” means something completely different from “extreme cutter”. “Sharp” just refers to the edge on the knife, and anyone who views knives as a hobby should be able to sharpen their own knives at least as sharp as any maker, in many cases probably sharper.
What makes a knife an “extreme cutter” is the geometry, or the way the knife face is ground. It sounds like you’re looking for a knife that’s extremely thin behind the edge, possibly what’s referred to as a “laser” - a knife which is both thin behind the edge and thin at the spine.
I’d suggest filling out the questionnaire and making a new post asking about recommendations for an “extreme cutter” in your price range. You’ll probably get much more meaningful responses that way.
And as
@M1k3 implies, if your knives aren’t sharp you should probably start there instead of with a new knife. The sharpening sub-forum can help you out if that’s the case.
