What is the fastest way to get a diamond sword down to 1 durability in Minecraft [Bedrock] PC

Yes, you read the title right. I need to get a diamond sword to one durability in Minecraft Bedrock Edition (technically it’s Education Edition, but there’s probably no difference). Since Bedrock is stupid and doesn’t show item durability, and Minecraft tends to have a lot of weird if-then statements that might mess with it, and that’s why I decided to ask Reddit. This is PC obviously (unless there’s a way to get Education Edition on a ps4)
