Achievement by having enchanted sword at a certain level of a certain material

I want to do an achievement that requires having a sword of a specific material that is enchanted with a specific enchantment at a specific level (In this case Sharpness 5). I know that it should be done with a procedure and I know more or less the base, but I don't know if the way to detect if the sword is enchanted and if it is enchanted at a specific level is fine. Can someone confirm if it is ok or not? And if it's not right, can you send me an image to make the correction?
Thanks
