4. DeWalt DW331K Jigsaw

Why he'll love it:

Jigsaws are the perfect tool for accurately cutting precise irregular lines in thinner materials. The DeWalt DW331K is one of the toughest and most powerful jigsaws available with a 6.5amp motor that delivers up to 3100 strokes per minute. With a saw like this, your Dad will be able to slice through even the toughest materials like a hot knife through butter. OK, maybe not that easily, but you get the point. The all-metal gearbox ensures long life and a keyless blade change system makes it easy to change blades without the need for an allen wrench.
