hehe...though Bob may cringe to hear it as I am the hackiest of hacks....I 
second the driveway method...I've used it to flatten and de-wedge 3 
different portland cement tools...works great if you can find a nice flat 
chunk of paving...my favorite yet is the 1 meter squares that make up the 
sidewalk in front of the elementry school across the street from my 
house...though passers-by look at me a little funny if i'm out there 
grinding a cement disk on what i like to refer to as #5 grit.... ;)
