The curved surface of the blade allows metal to flow over the blade when cutting curves. This feature applies to which snips?

• A. Straight-blade snips
• B. Combination-blade snips
• C. Aviation snips
• D. Tin snips

Answer: (B)

A curved blade surface helps metal glide smoothly as you follow a bend, reducing snagging and tearing when cutting curves. Combination-blade snips use one curved blade along with a straight blade, giving you a curved edge to guide the cut and still offering straight-cut capability when needed. That curved edge is the feature that makes it well suited for curved cuts, since it lets the metal flow over the blade rather than catch on a flat edge. Straight-blade snips lack that curved contour, which makes them less effective for curves, while aviation snips are designed for curved work but rely on their own specialized blade geometry. So the curved blade aspect that enables smooth curved cuts points to combination-blade snips as the best fit.
