From Ideal Heated Knives Website:

"Purchasers most often use Ideal Heated Knives for cutting, grooving and siping rubber tires of most kinds. Competitors have closely copied the outside appearance of our products, but theirs are far different on the inside. We are the reliable, time-tested, American manufacturer, with satisfied purchasers throughout the United States and worldwide. We also are the only company we know producing blades and other accessories in a large variety of sizes and shapes so that you can do the exact job that you need to do.

Our inexpensive, hand-held tools are constructed for easy, efficient and long-lasting operation. The solid brass head keeps strong, constant heat on the cutting blade, which rapidly heats the material to be cut. The depth of the cut is controlled by the adjustable blade. The brass heads and razor-sharp blades are available in nine different widths. Blades also come in five different strengths and a variety of tip shapes".
