I finally got around to picking one of these up. I was at Patel Bros. grocery buying ingredients for paneer bhurji and curry paste and I asked the cashier about the coconut scraper. She pointed towards a gentleman (manager? owner?) standing near the entrance. I spoke with him and after a brief exchange and hand gesturing (you know, the universal sign for coconut grater, sort of like the sign for 'he's crazy' but not near my head) and he left the store for a minute, headed a few doors down to open up Patel Bros utensil and handicrafts store and came back with this:
I spent a grand total of $40 at Patel Bros ($8 for my scraper, the rest for 4 bags of groceries which included some nice coconuts, Whole foods are you listening?).
I've been wanting one for a while and
this thread made me want to get one even more. Last night I grated/scraped a coconut using Bill/SFNM's trick of putting the scraper piece into my drill. Unfortunately, my cordless drill ran out of juice so I used my cuisinart (I was making coconut milk so it didn't matter). But it seemed to be working great (for the 20 or so seconds before the drill stopped). My drill's charging so the next batch will def. be made with the scraper.
edited to add that Patel brothers is at 2610 W. Devon
