I've had several with the same marking but different sizes. Sorry - can't tell you what they were. Only that they were variable.
After draining all the blood, you can use a set of digital calipers - using a small flat, hard, rigid surface against the table which reaches out to the tip. A small piece of glass, lucite, etc. works well for this.Canadiain said:Hey Ed, what the kosher way to measure the tip size?
