This invention relates to a pencil sharpener blade assembly and a pencil sharpener, specifically for stationery. The pencil sharpener blade assembly includes a blade holder body, a blade, a screw, and a side clamping component. One side of the blade is fitted with the blade holder body, and the other side is fitted with the side clamping component. The screw is offset from the blade and connects the side clamping component and the blade holder body, ensuring that the side clamping component evenly presses the blade. The advantages of this invention are: it avoids the screw directly penetrating the blade, fundamentally eliminating the localized stress concentration at the mounting hole caused by the screw penetrating the mounting hole; the side clamping component is fitted and pressed tightly against the entire side of the blade, applying uniform pressure to the blade and preventing problems such as loosening, cracking, and breakage caused by the reverse force of pencil cutting, significantly improving the reliability of blade fixation.
