I actually like the 3/8" (or 10mm) size better. But 1/4" will work.You gotta be able to afford this - HHIP 2000-0071 1/4 X 4 Inch HSS Extra Long Square Tool Bit : Amazon.ca: Industrial & Scientific
As good as a Reed Geek as per skeller047 's recommendation. I posted this mod earlier in the thread.
I don't get that intense on my Rico Orange box reeds. I now give a simple scrape to clean the reed on a glass plate and then play. But to each their own.
Note that the Reed Geek has some extra machining to allow you to work on the front of the reed. If that works for you, great. I'm not saying it doesn't work, but sandpaper is better and faster... for me. I have used the Geek in a pinch, but it's easier to blend contours with sandpaper.
For the back, though, anything flat with a sharp-ish edge will work just fine.
