I plan to use Homasote on my layout and want to decrease the dust factor when cutting. I have heard knife edge saber saw blades will help. I am currently using a Ryobi saber saw. Would anyone know of a site to find the knife edge blades? I have searched the net with no luck.

Sears sells them - you get one in an assortment pack you can buy on-line -- I'd go to HD or Sears or Lowes directly to see what they have in teh store.

And, while they do drop the dust to next to zip, these blades burn out very quickly.... If you can, just take it all outside, put on a dust mask and stay up wind.

Better yet, if you have a bandsaw - that works very well and you can add a bevel at the same time.

I used knife blades for a long time when I was cutting homasote, and then switched 100% to my bandsaw.

Thanks, mwb.
Good advice.

I use razor knife. Just press down and score where you want to cut then keep going over it untill it cuts through. I get a nice clean cut with no dust.

I needed to get a replacement set screw for my makita sawsal, and foudn this site
ereplacementparts.com

They were quick and had just want I wanted plus I found the blades for the sw as well.

Might want to try there.
