No, not quite as "thin". Smoky the Chive is a very small knife. If that's what you're looking for I think you'll be satisfied. If not, you may not be satisfied.
Below are comparisons between a Leek and a Scallion (in the middle size wise between a Leek and a Chive). The photography is faaar from professional but it will give you some idea as to the blade because the Chive blade has the same profile as the Scallion, it's just shorter.
The Leek blade is about 2cm at the pivot and the Scallion is close to 3cm at the pivot.
I bought a Chive several years ago and sent it back because it was too small for my meat hooks. Now I wish I'd kept it just so I could have one and the prices have gone up significantly since then.
The Chive only comes in black and rainbow (& maybe silver). Here are the Tech Specs for the Chive.
