Garlic needs irrigation to grow bigger bulbs and I didn't get mine near enough water so the varieties are varying widely in size.

I use the fork for potatoes and for garlic. It works wonders for the garlic especially since I plant in 5 wide rows. Each bulb is 4-6 inches apart so takes 2 fork widths to harvest each sub row. This fork is missing a tine though as I snapped it on potato digging a couple years back.
