I have an older Fein multi-tool. This is the blade I use the most and almost always when I don't want to make a huge mess or need to stay on my pencil line while cutting in place. I've purchased some of the generic blades but haven't found the off-set type. Fein needs to come out with this blade that can handle nails but if you're careful and switch blades that can handle a nail or two when necessary, these blades will work great for quite some time.
