How do i sharpen my meth needles?

bricks are much too coarse of a material to put a fine point on the needle of a syringe. I used to use my fingernails. You squeeze the tip of the needle with light-moderate pressure between the nail of your index finger and the skin fingertip of your middle finger and then pull the needle down sliding it through the point where they come together. After you use a needle the very fine tip gets bent or curled. I say a magnified picture of a syringe used 5 times at the needle exchange which is a place where you take your old needles and they give you new ones, and the tip was curled backwards about 150 degrees. When you pull it back through your fingernail and tip like I described, it straightens the tip and makes it alot sharper or at least alot more capable of the skin and vein much easier. Don't use those fu.@ked up bent and dull needles if you can avoid it, they can really do damage to your veins. See if there is a local needle exchange in your area.
