Forrest Manufacturing Company, makers of the extremely popular Woodworker II blades, have been busy in the last year with four new offerings — all but one expanding the Woodworker II line. Take a Woodworker II combination/general purpose blade and square off all the teeth, and what do you get? You get perfectly clean 90° bottoms on slots, and no scoring marks when cutting rabbets, and box and finger joints. The 40-tooth 10" square-top blade comes in both regular and thin-kerf versions, for about $120 in 2011.
Meanwhile, a thin-kerf version of the venerable 10" Woodworker II also became available in 2010. Featuring 48 teeth with a 20° hook angle and 25° alternate top bevel, the thinner blade is well suited for underpowered saws. The blade went for about $134 in 2011.
As long as we’re talking thin, Forrest has taken the concept a step further with its new Ultra-Thin 080 Woodworker II blade. Originally made as a custom blade several years ago, the company added it to its regular line in 2010. The 40-tooth blade uses ATB teeth with a 20° hook and has a kerf that’s only .080" wide — about 5/64" — and offers little resistance when cutting due to the extremely thin kerf. (Forrest recommends using a dampener/stiffener with the blade for better rigidity and vibration control.) In 2011, the blade sold for about $132.
Finally, Forrest’s Duraline tenoning blade is designed specifically for use with tenoning jigs. The blade has 60 ATB/raker teeth with a 10° hook, and sold for about $177.
