i just sent in a 9530 mini auto stryker for a new blade. the current one is a coated/serrated one, and i called and confirmed they had satin plain ones in stock. it only cost 20 bucks, including shipping!
they said since they stopped making them, eventually they will run out of blades, but that the springs and buttons will be able to be warranted/repaired for life. so that is nice to know.
anyways, i should have it back by next weekend, i will let you all know how it goes, good i'm sure!

excellent!
