This blade will perform well on most types of hardness rock

It has held up extremely well and cuts just about most kind of rock, from the very soft petoskey stone fossils to hard jasper, petrified wood, geodes

We don't recommend using this blade to cut too hard materials, such as: agate with a Morse hardness of 6-7. Because it is difficult to cut or the blade will be damaged quickly

A high concentration diamonds are crimped into the blade rim

More diamonds in the notched rim and a stiffer core make this blade cut faster and provide a long use-life

These blades work well with most lapidary materials and are a very affordable alternative to name brand blades

New, Unused Blade - Not in Original Packaging

These blades were originally packaged in oil so you will see several oil spots on the surface
