Think about that. How often do you hit a foreign object that
does not hit both sides of the blade... It is possible but less
likely than the whole blade hitting that object.

Depends on what you're using the saw for. Roughing cabinet plywood
to size almost never involves hitting foreign objects of any sort.
In home remodeling, though, it's pretty easy to almost miss a nail
head, and dull only one side of the blade. In my experience, in
that type of work, it's much more common to hit a nail with only
one side of the blade than full-on.

Not trying to drag this to prove who is right... ;~)

When remodeling, removing a wall or cabinets I always used a bimetal
recip saw. The blades are made to cut through nails cause you are going
to cut through nails. ;~)

BUT my above thoughts were me remembering cutting through finish nails
on my TS looong ago.. I do not recall the reason but it happened. I
tried not to do it and fortunately there was no issue.

And having said that I was always using carbide toothed blades.










Either way the blade apparently was worn out. LOL

BUT what you said would certainly cause the blade to track off
center.
