Armour Bottle and Jar Cutter

Bottle and Jar Cutter is a fun way to recycle your round or square bottles and jars. Kit includes: Adjustable bottle cutter, 2 cutting wheels, glass tapper, adjustment wedge, five glass sanding sheets and a 24 page full color bottle cutting reference guide. Made in US.
Each bottle cutter assemble has TWO cutting blades. One is visible. The second one is only accessible after reading the attached instructions, which requires that the unit be partially dis assembled. The item do not cut the glass like a knife cutting a sandwich. The score line, which is a subtle line, needs to be tapped from within the bottle with the supplied tapping rod to run the scored line. Thus separating the top from the bottom half.
