What's the difference between the straight and curved tips?

Straight tip cuts in linear paths—good for trim strips and edges. Curved tip follows contours and handles detail work around corners and complex shapes. Having both lets you pick the right tool for each cut.

Can these cut through trim adhesive or hardened material?

Micro tips excel at precision work on soft trim, vinyl, and rubber—not designed to cut through dried adhesive or hardened plastic. Use them for clean removal of flexible trim pieces before adhesive sets.

Do I need any other tools to work with these snips?

No—these are standalone cutting tools. Pair them with a heat gun if you're removing adhesive-backed trim, but the snips themselves need nothing else to operate.
