Re: I believe the Kerf is .098", and more..

>I was almost positive that I read that the kerf of the Fusion was 0.098" too. I recall being pleased because that's the width I'd want. Amazon now has it listed as 1/8" (0.125") full kerf.
I haven't compared the Fusion to the WWII, but the Hi-ATB and double angle side grind do give the Fusion some advantage is cut quality....at least until it dulls. The Hi-ATB is the cleanest cutting grind if all else is equal...it's also the fastest dulling. The demo I watched was impressive.
As as blade quality goes....when I started out I had a 36T stock Delta blade that didn't give what this rookie a satisfactory cut. I went out and got a $20 Oldham 60T blade that was a huge disappointment. I then tried a Vermont American 28T ripper for $15....also a disappointment...same with a similar Skil I picked up for $7. All of these blades offered alot of resistance, saw marks, and splinters. Then I tried a Freud LU84 that was much better. ..finally a good cut! About a year later a friend gave me a WWII TK that was amazing even compared to the very good LU84.
I've since tried over 30 blades mostly out of curiosity, and I do find huge differences between the better quality blades and the cheap ones, which I now call "bludgeon blades" as they hack their way thru the wood in comparison. There's alot more to it than just tooth count. The sharpening makes a huge difference, as does the body stiffness and flatness. There are definitely bargains to be found...right now the DW7657 is on sale for $32. This is a blade that rivals my WWII....as does the Ridge Carbide TS2000, and the Tenryu Gold Medal...I'm sure there are others...possibly the Fusion, F410, Infinity Super and others. The Freud LU88 actually cuts cleaner than any of the 40 or 50T GP blades I've used and still rips respectably well....$36 on sale right now. To get a better cut than the WWII, you typically need to take the leap to dedicated specialty blades...but even then you need to stick with higher quality or the cut suffers. A good 80T crosscut will definitely leave a cleaner cut than the WWII, but it'll burn easily and bog down on rip cuts.
It's important to note that many manfactureres make multiple lines at different price and quality levels, so it's not really valid to compare brand name alone unless they only have one line...like Forrest, Ridge Carbide, and Infinity. Freud, Tenryu, and DeWalt make several quality levels...some excellent, some not. It's also very important to select the right blade for the right job. Choosing a Forrest ripping blade for crosscutting would surely yield a splintered cut. Equally important is the saw itself, and it's setup....is there a ZCI? Is it flat? Is the fence parallel? Does the saw vibrate? Does the arbor have runout? All these factors affect the cut. A lesser saw will mask the subtle differences between blades.
I could easily live with the offerings from Ridge Carbide, Forrest, Freud's better lines, DW's better lines, Leitz, Ridgid, Infinity, Tenryu, and probably many others that I haven't tried. I do stray from the cheapie blades...BTDT. I don't need the ultimate edge on every cut, but most of the better blades I've tried are capable of a glue ready edge.
