I've been using an X-acto knife for a while now to cut the tips of my fingers (on the top part on the side by the nails). Because this is a sensitive area, it causes a decent amount of pain without requiring much damage, and it doesn't seem to leave scares. The reason for posting this is, I want to know if this is a good substitue for cutting where it'll leave scares, and I would like to know what other people who self harm think of this method. I'm well aware of the rubber band method, but I NEED to see blood along with the pain. I'm not encouraging self harm, and I'm sorry if this thread is against the rules. I'm new here and have joined because this looks like a good site to talk about these "things".
