Infini Model 窄型鑽石錐形銼刀 3入組

I was surprised by how much control the flat handles give me on these tiny files—much better than round ones. The super-fine grit polished a tricky inside curve without any scratches. For the price of three grits in one set, this is a solid buy.

The super-fine grit on the 2.5 mm tip is perfect for getting into tight corners on resin pieces without scratching the surrounding area. I've already used the medium file to shape and the fine one to smooth, and the diamond coating hasn't worn down a bit after a few hours of work.

The flat handles give way better control than round ones when I'm doing fine detail work, and having three grits in one set means I can switch from shaping to polishing without pulling out another tool. The 2.5mm width is perfect for reaching tight spots on my jewelry projects.
