As a union laborer on the trans-Alaska pipeline project, I once had to cut truckloads of rigid foam insulation with a table saw. Clouds of noxious, statically charged dust billowed from the saw, some of which inevitably ended up in my lungs. I could have reversed the saw blade to reduce the dust, but that would have produced more fumes. Cutting with a utility knife would have been too slow and tedious.

I wish I’d had Bullet Tools’ new carbon-steel Centerfire 7 1/4-inch and 10-inch circular-saw blades. They have a knife edge instead of saw teeth and are designed to make swift, factory-smooth cuts in foam panels and insulating concrete forms while eliminating 95% of the dust.
