Changing edge style of formica countertops
If the whole countertop is formica. That means the top, the front 45 degree bevel and the front facing, you will need to remove the entire top from the cabinets, take it outside or the garage and cut off the bevel area. You will then need to add a piece of stable wood to the front. You will then need to prep the top to accept a new layer of formica. You will need to use a router to trim the various edges.
When you're done, you will reinstall the top.
The question is," Is this in your skill set?"
