I have a similar story, I was planning on making homemade paper with my sister by blending up newspapers in our blender. Except, I was too stupid to figure out how to open the blender lid, which was held on with a suction, which is opened with a button. I eventually got it open by forcing the lid open by holding it upside down and forcing down with my left hand. The blade fell out and sliced my wrist open horizontally, at first I didn’t realize until I looked down and saw blood gushing onto the floor. I told my sister to help and get our grandma who lived on the property but in a different building. Eventually we got to the ER and they gave me a bandage, but refused to give me stitches without my mom being there (I don’t know why they did that it was stupid). Eventually my mom left work, she’s a nurse, and gave me liquid stitches. She said she didn’t do normal stitches is because I just barely missed an artery and it was exposed to the air, and she didn’t want to risk poking it with a needle. I do wish I had normal stitches done though because the wound kept opening when I went to school, causing the scar to get pretty big.
