This is the largest of the spindle roughing gouges offered by Hamlet of Sheffield England,  in a 1 3/4" version, without handle.
Although large, I use this size for everything from ink pens to porch columns.  The larger the spindle roughing gouge the better you will find it will level a cut--wonderful for cylinders, tapers, shallow and wide concave or convex area.  This is for work with the grain running parallel to the lathe bed--NOT FOR FACE-GRAIN BOWL TURNING!  Using these types of gouges for such work can result in a bent or broken tool, with serious safety concerns.   Overall length is 8.75", with the flute about 5.75" long. 

This is 1 3/4" from the outside of one flute to the inside of the other  (English method of measuring).   I only offer this tool without a handle.  I am a huge believer in making your own handles--read the article on my www.alanlaer.com site, under Articles:  "Forgotten Handles."
