Two Types Copper Coated - for strength, easily peels off - scrape a bit off with a knife then peel off desired amount of graphite to expose, one end uncovered and pre tapered. The copper coating is ideal for the smaller sizes as they last much longer under high stress use. The 1/2 inch size is a perfect economy bowl push.
Uncoated Graphite - Our graphite rods are of the absolute highest quality. They are extremely dense and strong, perfect for shaping and durable for high temp use.
