The Chef Craft 21629-2PK nut cracker set seems pretty handy for dealing with a variety of nuts. It comes with two nut crackers and four picks, so you're covered not only for cracking but also for getting those pesky bits out of the shell. From what we've gathered, folks have successfully used it on hazelnuts, walnuts, pecans, and almonds.
Aside from nuts, this set is also a bit of a multitasker—it can help you crack crab shells or even break apart hard candies. The nut crackers have an ergonomic design, meaning they’re not a pain to use, even if you’re planning a nut-cracking marathon.
But be aware, they might struggle a bit with very hard or large nuts, so it’s not completely foolproof for all shell types.
There’s a note on maintenance too. The stainless steel should mean durability, but some have mentioned rust issues after a while. To avoid this, it's best to hand wash them and dry them thoroughly, especially if they're stored in a humid place. Doing this should keep them nice and rust-free.
In general, if you're looking for a reliable tool for cracking nuts or even a few other hard-shelled treats, this set could be a great choice—just remember the upkeep part to keep it in good shape.
