"We use the Groz beckert 134 SAN 11 #18 needle it is titanium coated reduces friction and allows the needle to be cooler and is much harder for less needle deflection. It has a special design scarf which allows for better timing of the hook this allows us to bring the point of the hook closer to the needle. this helps in forming a better loop which translates into less skipping of stitches. Regarding the shank of the needle it is larger than the body of the needle below the shank it will be thinner until the eye of the needle. The standard 134 and 135X7needles are much different."
