This handy set includes three long, rectangular blades (approx 5"L x 3/4"W). One long edge of each blade is honed to razor sharpness; a removable protective rubber spine (included) slides onto the blade you're using to ensure a safe and secure grip while cutting. Blade styles include:
• One rigid blade (5-1/2"L) ideal for straight cuts.
• One flexible blade (5-1/2"L) ideal for curved or arcing cuts.
• One crimped blade (4-3/4"L) that provides a zig-zag cutting edge.
