I was watching a “How it’s Made” episode on TV and there was one about how they make circular saw blades. They showed the steps they go through to make a saw blade and a fleeting view of a blade with the Festool name on it and what looked like a 1” hole for the arbor. That would indicate that Festool makes 12” and larger blades. They also showed blades with the Leitz name on it, so I’m assuming that Leitz makes blades for other companies. I don’t think Festool makes their own blades. Just an observation.

That is a great show! I sometimes wonder how long it must take them to negotiate access to some of these places, and I wonder what vetting of video occurs to keep the industrial secrets they must run across. I would think that it is not the tooling so much that makes the quality of the blades but the metallurgy of the blanks that go into the blade so it doesn’t really surprise me that one factory turns out more than one company’s blades.

Festool doesn’t make a 12” blade. They do have a different arbor size. I also believe that someone mentioned that Leitz makes the blades for Festool.

Leitz has multiple plants in Germany and China, and makes blades under lots of names. Some that come to mind were the older Delta Indstrustrial blades, Irwin Woodworker series prior to the introduction of the Irwin Marples line, Schumacher and Sohn, Leitz Pro, Lietz, Craftex Blue Tornado, Onsrud. They’re almost always industrial caliber blades. I’ve heard lots of positive comments about the Festool blades. I’ve never seen the Leitz video, but have seen Delta (USA), DeWalt (UK), and Irwn Marples (Italy) blade manufacturing vids….they’re really cool.

In today’s high tech world, I don’t think there are too many unknown trade secrets for blade technology. Quality is more a matter of a business decision and commitment than it is developing any new breakthrough technology these days. The latest technological development I’m aware of is Cermet tips, which have been out for a while now, but they’re expensive and don’t yet have a strong enough business case to mass produce them.

Knotscott, Carbide Processors has a 10” 40T combination blade with cermet II teeth for $95.61. There line of blades is touted as “World’s Best”; prices seem to be comparable to Forrest blades.

”Knotscott, Carbide Processors has a 10” 40T combination blade with cermet II teeth for $95.61. There line of blades is touted as “World’s Best”; prices seem to be comparable to Forrest blades.”

Maybe Cermet’s time has arrived, or is close at hand, but they’re still not mass produced by large market standards. I haven’t tried them yet, so I can’t say how they do from first hand experience, but I would consider Carbide Processors research on tooth materials to be at the forefront of what’s out there. CP has had their “Cermet II” blades out for a year or so with promising results. Now it’s a matter of information sharing and education so that the market place is asking for Cermet.

Here is the video : http://www.youtube.com/watch?v=UoHCR7-IYMA

Found it interesting that one step is the ‘Straightening Specalist” whos job it is to beat on the blade with a mini-sledge to remove any ‘bumps’ and then check for flatness just using a straight edge and eyeballing it.
