Butcher Knife Free low-poly 3D model

A simple butcher's knife, the handle is glued to the blade, there are small artifacts, I don't know how to remove it - I've already applied the simplification. This is my first model, I would appreciate your constructive criticism. In the future, I will continue to make knives for various purposes, maybe there are wishes? I noticed that there are not enough free karambits and butterflies in the store, I suppose I will increase their number.
