If one cannot blow out the match after lighting, one cannot extinguish by shaking it either, right? I’ve seen people drop the still burning match on a non-flammable surface (ie the tray for the leichter), but I shake it out since I was taught not to blow it out, as I shake out any lit match or candle to extinguish it, as quark2 suggests. I also assumed that I am not mekabel Shabbos until I say the bracha.
