I've taken #3 soprano reeds down to playable strength by merely scraping the vamps with a sharp pocket knife . . . keeping the reed clamped to the mouthpiece, I hold the horn under my arm upside down, rest the mouthpiece's vamp on the edge of the kitchen sink, scrape off a bit of sawdust, rinse, test, and repeat. Works for me. No fancy tools, either.
I do this to almost all reeds out of the box (usually I'm using #2 reeds). DAVE
