Cut the old olive tree back to four trunk nodules with one blade to encourage new healthy growth. Even wedged a blade tight in my rookie ignorance of cutting underneath the larger branches, but pried it loose after much finagaling and the blade did not bend or break. I learned a lesson in cutting without damaging saw or blade, which is a big plus. And that olive wood is tough and heavy but the blade did not hesitate even on the trunk sized branches. I've trimmed smaller trees and took out damaging roots in the past with different blades but none have held up like this Ax blade. This was a big job, the largest tree I've worked on. I'm still using that same blade to cut fire wood from the large portions of tree. I'm impressed with the product.
