Maybe this is obvious to all, but I've done alot of searching, and I have yet to see this mentioned before...

I recall someone asking what the best way was to crush rocks to the finest possible powder in the quickest manner. Picked this little gem up at the grocery store earlier today, and I must say in my 20 years or so of breaking rocks, this is by far the cheapest, best ways to go. Sure you can buy a 45.00 deering spice kit, and achieve almost as good results, go to you local new age store and blow 20 bucks on a rather large mortar and pestle which will raise all sorts of why do you have that? what is that for? do you do what I think you do with that? type questions. This obvious little gem is all stainless steel, has an extremely fine mesh screen, looks like it will last forever, can be kept discreetly in plain view in the kitchen drawer, and will shred through an 8 ball sized rock in under a minute. Just tried it out to be sure, and it works AWESOMELY- price $3.99 +tax If you dont have one of these, I suggest you pick one up right away. after trying it out a couple times with small amounts, then one big amount, the technique is like shredding cheese - dont try to force the rocks through the mesh, rather use a small (blunt) metal bar to sort of grate the rocks through the screen. This is a significant discovery for me. No more tedious choppa chop chop, no more missing chunks and ending up with rock holes in the sinuses. The perfect tool for your cosmik debris'
