I have three high-end blades:
* Woodworker II, standard kerf (WW10407125)
I wish I had bought the standard kerf Woodworker II in the "modified #6" configuration with the raker tooth for flat bottoms (WW10406125):
* Woodworker II modified #6, thin kerf (WW10406100)
This is the "modified" blade type recommended by Forrest's expert (see below), although I wish I had bought the full kerf version. Someday.
* Freud Premier Fusion P410:
This is the blade I bought after talking with Freud's representative in the store (see below).
In addition, I have some "free" blades that came with my table saws and other cheap blades that I use for cutting up scrap and harvesting wood from old furniture.
Comments about Terminology - General Purpose vs. Combination:
Most of us think of general purpose blades as having ATB configurations with evenly spaced teeth and uniform gullets.
Most of us think of combination blades with groups of five teeth: four ATB and one raker tooth. There is a larger gap between the groups of five teeth, and the gullet there is also deeper.
As noted above, you can buy the Forrest Woodworker II where every fifth tooth is a raker tooth. I have one of those blades. The spacing is the same as a general purpose blade, but the raker tooth is like a combination blade. What do you call it?
Not everyone agrees on the terminology anyway. The March/April 2018 issue of Fine Woodworking magazine has an article on "Combination Sawblades." Despite the article's title and text, many of blade label images have "General Purpose" printed on the blade labels. Even though the article compares "combination blades" and uses the term throughout, every blade pictured has evenly spaced teeth and evenly sized gullets - what we would call a "general purpose" blade.
Fine Woodworking Magazine Test Results:
The author compared eight full kerf blades. The author tested crosscut quality in pine, cherry, and plywood, and rip quality in pine and cherry. He also measured rip speed in 8/4 maple.
The author awarded "Best Overall" and "Best Value" to the Freud Premier Fusion P410. He also awarded "Best Overall" to the Forrest Woodworker II and the Ridge Carbide TS2000.
The comments were that the Freud Fusion yielded the cleanest crosscuts and rip cuts, but the rip speed was slow. The Forrest Woodworker II was "clean and smooth" in pine and cherry with some chip out in plywood and light scoring on pine. The Ridge Carbide TS2000 had clean crosscuts, fuzziness in plywood, fast clean rips, but light scoring in softwood rips cuts.
Conversations with Forrest and Freud Experts:
I have spoken with the Forrest technical support expert about their blades. He was the one who encouraged me to buy the modified #6 Woodworker II blade, saying it was just as clean cutting as the regular ATB-only Woodworker II blade, but with faster rip cuts and a flat bottom. My friends have suggested that it may result in more chipout on the bottom of the workpiece. I haven't noticed "more" chipout than the ATB-only blades. I still get chipout, especially poorly supported cuts where I expect it.
I happened to be shopping at the Rockler store when the Freud representative was visiting. He encouraged me to buy the Fusion blade. His arguments for Freud Fusion over Forrest Woodworker II were:
* Freud makes their own C4 carbide and he says it is better than the carbide that Forrest buys from someone else.
* Forrest blades are a solid product, but it is their sharpening that makes them special. He says that if you let the local sharpener sharpen your Forrest blade, you will get a good, but ordinary blade. (I wonder if you send your average, run-of-the-mill blade to Forrest for sharpening, you will get a "better" blade?)
* Freud's Fusion blades have a high-ATB angle for cleaner cuts, and the face grind and side grind are special to reduce friction and heat.
He sold me. I bought the Fusion but have made only a few cuts with it. Despite the Fine Woodworking review, it yielded about the same level of scoring marks as the Woodworker II blades. (I have used it only on red oak so far.) I need to try it on more woods and cut types.
I hope this helps someone.
