Be careful to order Pin end if that is what your saw uses. If you can use either, for the thick more or less straight cuts the pin ends will probably work better for you also!
There are conversion kits available for some saws for plain end blades if that is your preference.

I met him personally because of trying to find a decent place to buy blades!
