Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to crack macadamia nuts [title] Gather tools. [step] You can make a makeshift macadamia nutcracker with a vise grip, an iron bar to set the nut against, and a flat hammer. [substeps] Vise grips are common tools available at any hardware store.

Ending1: They are intended to be used to firm nuts into a square shape. They are common at hardware and natural items stores. Ending2: If you don't have access to them, you can opt to use a hammer. An iron bar comes in multiple types, with the main sizes being all roughly equal. Ending3: If you love macadamia nuts and plan to shell them often, it's worth buying a vise grip for this specific purpose (though you'll probably find other uses for it as well). Be sure the hammer has a flat end, rather than a round one. Ending4: A hand saw is useful for this project, while a hammer should work better for larger batches. If your workplace is designed for large batches, then you may wish to use a regular bar saw, but larger cutters will work better.
