Used the Milwaukee AX blade to cut up a tree trunk that was from 10 inches to 16 inches in diameter.  Numerous cross cuts were made to allow for small wood sections that would easily fit into a compostable bin.  The 16 inch section of the tree trunk was trimmed down parallel to the trunk to a smaller diameter using this blade that would allow an easy follow up cross cut.  All cuts were made with a single blade out of the package of five, and the used blade still cuts like new.  In addition the blade withstood various edge impacts while cutting wood in excess of 12 inches in diameter without bending or any deformation.  All in all an excellent product.
