Update* Revain is definitely not the place to order them. 2 out of 3 had problems. Last time I got the wrong blade delivered and the Revain driver was kind enough to throw an empty water bottle onto my porch. The first one I got was perfect and lasted several months. The second one I got had a sweat crack that caused the blade to bounce when cutting unless I slowed it down. I ordered another one hoping it will be as good as the first.
