Scratch n’ Dent Special: Bad Dog Blue Blade (Legacy Version)
We recently updated the Bad Dog Blue Blade to include a knockout center for worm drive saws—but we’ve still got a limited stash of the original version without the knockout center, and they’re every bit as tough as you’d expect.
Part of our Summer Scratch n’ Dent Yard Sale, this legacy version of the 7-1/4" Blue Blade features a solid steel core and a diamond-coated edge designed to rip through masonry, metal, tile, composites, plastics, roofing, and more—all without changing blades.
Cuts masonry, metal, tile, PVC, Stainless Steel and more
Industrial diamond edge – no teeth to chip, no slow-down
Steel core – durable, and runs cooler than abrasives
Works in standard 7-1/4" circular saws (not compatible with worm drives)
Lifetime Guarantee – if it fails, we replace it
This version lacks the worm-drive knockout, but it still cuts like a beast. If you’ve got a standard circular saw and want a killer deal on a blade that doesn’t quit, grab one while they last.
Looking for the updated version with worm drive compatibility? Check out the current Blue Blade—same grit, now even more versatile also available in 10".
Dull or damage our tools and we will repair or replace them.
