The original PipeKnife® is one of the most used long knives in the industry. I think the extra long PipeKnife® is destined to become one of the most used knives also. The flattened blade shaft is 8-1/2" long and rounded at the corners. The overall length of the PipeKnife® is 18". It is made of cast aluminum and has a steel nut cast into the aluminum for the blade clamp screw. One of the nice things the new extra long PipeKnife® has is a slot cast into the end of the handle that lets you store extra blades. Made in the USA by the same people that make the original PipeKnife®. Does not include blades.
