If the knife cuts your finger, it will break or bleed. For bleeding, local pressure should be applied with sterile gauze or some clean paper towels should be temporarily applied to the wound for pressure, which can play a role in local compression and hemostasis.

For tiny blood vessels, local compression can stop bleeding. For the case that the incision is deep and the artery is injured, the finger vein or artery near the heart can also be blocked to stop bleeding. At this time, you must go to the emergency department of a regular hospital for wound debridement and suture, and if necessary, you can perform vascular anastomosis.

If the knives and instruments at that time were dirty after the operation, it was best to take a tetanus shot to prevent the possibility of tetanus. Therefore, for minor knife injuries, you can handle them at home, and for more serious sharp injuries, you must go to a regular hospital for treatment.
