I bought these blades in December, 2006, and have used them on hardwood and pressure treated decking.  They give a smooth cut with little or no tear-out, but they do deflect a little.  I would definitely recommend them though, as the cut is really clean.  I can't figure out why amazon raised their price to above what the retail big-box stores carry these for, makes no sense to me.  Amazon's price went to double what I paid just 6 months ago at amazon, yet the Marketplace sellers still have it at half the price.  The India-based customer service reps were of no help when I asked about the price change.
