Issues with finished wood cut with the wrong saw blade
So this is my first time building anything with wood, I’m trying to make a desk. I bought a big sheet of finished wood from Home Depot, I had it cut there BUT they cut it with the wrong saw blade now I’m stuck with wood that is all jagged on the edge of the face…. how In the absolute world should I go about fixing it??? I tried sanding but the splintered edges go through the first layer of wood. I did research and thought I’d use a block plane to slice the layer off but a home depot clerk suggested against that, now my only idea in mind is to just use a circular saw with a finishing blade to take a whole quarter inch Of wood entirely. Any ideas or suggestions? Thanks in advance.
