It comes in two pieces, a bottom tray, and a grid that is hinged and has a handle. Then, to break the ice, you just torque the handle, which shifts the grid angle, forcing each cube to move and come free. Works best if you move the ice to a different container at this point but you don’t have to.

If you do a search for “metal ice tray”, it should come up in the images (to avoid linking an amazon image).

I like it better than the plastic trays for this. Both can be a pain in the ass but in different ways. Plastic trays can snap when you bend them (haven’t had one snap in half but I have had one snap some of the structural supports) and often the ice just settles back in its place after you loosen it and you need to “bounce” it a bit until the ice turns in the cavity so you can grab it. With the metal tray, it doesn’t just free the ice easily when you break it (though still easier than the bouncing game) and if you lift the grid part out, you’ll probably need to use a different container or just leave the grid off until you make new ice.
