I’m pretty sure that generally some particles break off from either side whenever you cut something in half. When I cut paper with scissors I get a distinct smell, that’s clearly paper particles that have escaped into the air. Under the right conditions you may even see some dust.
When using a saw it is very explicitly removing material to create a gap between the two sides. You can see this clearly in a lot of woodworking videos on YouTube. For other tools like a knife, it’s not as obvious, but I still think some material will inevitably be lost no matter what you do.
Maybe some extremely specialized nano-scale methods can cut things without losing material, but I doubt that’s something you can do on an everyday life scale.

I think so, but if I’m honest, there’s a chance I’m just imagining it 😅
