The smallest bore needle is typically a 27-gauge needle, which has an outer diameter of about 0.20 mm (0.008 inches). These needles are often used for very delicate procedures, such as injecting small volumes of medication or for drawing blood from fragile veins. Due to their thin size, they cause minimal pain and trauma to the tissue.
Yes, the larger the gauge the smaller the needle size.

No, a 20-gauge needle is smaller than an 18-gauge needle. The gauge number indicates the diameter of the needle, with a lower gauge number signifying a larger diameter. Therefore, an 18-gauge needle is thicker and has a larger bore compared to a 20-gauge needle.
A single needle prick obviously.
The needle with the smallest diameter for blood work is typically a 23-gauge needle. Gauge numbers indicate the thickness of the needle, with higher numbers representing thinner needles. A 23-gauge needle is often used for venipuncture in children or for patients with smaller veins, as it minimizes discomfort while still allowing for adequate blood flow.
You cannot chop a tree down with a knitting needle as the needle does not have a sharp edge. You could bore it down if you lived long enough.
