I love the ergonomic shape of the tool. It makes it much easier to tighten the needle. Each one is also unique so that makes it extra special!
My only issue is that only one of them was able to fit my KnitPicks cables, which apparently have a slightly smaller hole than knitterās pride. I had to go in store and try all of tools with my cables to find one that fits. If you have knitterās pride cables, I suggest trying the needle out in store too because from what I remember, they all fit but pretty tightly. I donāt own any chiaogoo interchangeable cables so I canāt say how well they fit.
