I need a heavy duty olive pitter!

[jsteinhauer]

And I can't find one. There are lots of tools out there called olive/cherry pitters, but none of them are stout enough to stand up to home cured green olives.

I bought ten pounds of green Sevillano olives last fall, and water cured half, brine cured half. The last of the brine cured ones are finished now. I like to use olives in martinis, on pizzas and in sandwiches, but the pits make that invconvenient for all three. I've tried a couple of the readily available, so-called "olive pitters" and both broke straight away. Any advice?
