What's the difference between T-shank and U-shank blades?

T-shank blades lock into the tool-free clamp — they're the modern standard. U-shank blades require a set screw and are being phased out. Always buy T-shank compatible jigsaws and blades.

Can a jigsaw cut straight lines?

Yes, but it's not ideal for long straight cuts — a circular saw is better for that. For short straight cuts, use a straight-edge guide clamped to your workpiece. Jigsaws excel at curves and detailed cuts.
