Laserkerf Laser Guide: Discontinued — What to Buy Instead

Laserkerf was a bolt-on laser guide for circular saws: a line projected ahead of the blade so you could follow a pencil mark without sighting down the shoe. It is no longer available.

Why saw lasers went away

Almost every circular saw and mitre saw sold in the mid-2000s offered one, and almost none do now. Three reasons, and they are all worth knowing before you go hunting for a replacement.

A laser cannot be more accurate than its mounting. It is bolted to a tool that vibrates. The line drifts out of alignment with the kerf and there is no way to know it has until you have cut.

The line disappears outdoors. A red line on sunlit plywood is invisible. That is precisely where most circular saw work happens.

Following a line by hand is the wrong technique anyway. A hand-guided circular saw wanders because the operator’s arm wanders, not because the mark was hard to see. Improving your view of the line does not fix that.

What does fix it

Physical guidance. A straightedge clamped to the work, a shop-made ply guide, or a proper track the saw shoe rides in. The saw then cannot deviate, regardless of how steady your hands are. This is the whole reason track saws took over fine crosscutting in plywood.

What to buy

The Kreg KMA2700 Accu-Cut, linked below, is the cheapest honest route to that: a guide track with an adjustable baseplate that clamps to the shoe of a circular saw you already own. You calibrate it once by trimming the anti-splinter edge with your own blade, and after that the edge of the track is the exact line of the cut — no measurement offset, no laser, nothing to drift.

A shop-made guide from a strip of straight ply does the same job for the cost of the ply. The commercial track buys you a non-slip base, a clamp system and something that packs away.
