These will dull a blade and you want even know it.

The OP said it was not detectable with a metal detector. If it's small enough, some detectors will not pick it up and others will.

Was not metal, it was hardened resin pockets. Not unusual to find in SYP.

I use to put old soda bottles found in the woods in the forks of young trees, found one the other day just the neck sticking out of a tree trunk, someone some day can write about sawing glass on a post in the future.

Wish I had a picture of the rock we put into the crotch of a yellow birch while blasting ledge in the green mountain national forest. It was 2'x2'x3' about 15' up in that tree. We had to take cover in a 60" culvert,broken windshield on two trucks. Boss says I think I put to many sticks in :D.

We hit some rock hard pitch in a big white pine on Monday.
It was so hard we had to change the band 8° cobalt
It started diving in the cut.
If I remember right the log had a 8ft scare in the bark that was healed over.

Here is what a crotch rock will do.

And then you change the blade. :-\

Many years ago in a mill that I worked at I was cutting some big walnut logs of about 4 feet diameter on a bandsaw with 6 foot band wheels and 12 inch wide band and I hit a jar of nuts and bolts that had been placed in the fork of a branch and had been completely covered over by growth, it tore about a dozen teeth completely off. Another time I hit bridge spike that had been hammered into a tree as they used to do to tie the horses to. Have also cut through 22 bullets, they show up as shiny spots and don't do damage as they are soft.

Already did that. Hit a Pepsi bottle in a Live Oak tree with my Lucas. Freshly sharpened blade, too. Did that saw no favors at all.
