Review on Kutzall Extreme Ball Shaft 6 3Mm by Doug Olson

As another reviewer said, these are not exact measurements - account for the extra space. At the very bottom of the seller's item description (which I haven't read and which is on me) it says the material is extra added. I bought an item to make the mouth of a fishing lure and ordered a size 3/4". It is actually only about 7/8" in diameter which makes it useless for my needs. However the product is like built a stone removes wood like no other and removes skin just as quickly, so use extra care.
