Cutter Brass Straight

The original, self-oiling, TOYO Brass Supercutter was introduced in 1976 and remains today as the most popular cutting tool among glass professionals in the United States. Manufactured with a heavy brass barrel it is a durable workhorse that will last a lifetime with proper care, maintenance and an occasional new blade.

This comes with a straight head known as a tracking head.  Great for straight cuts.
