I was looking for some high-quality replacement blades for my radial arm saw.  I've had this saw for about 25 years and have used a variety of different blades including the "hollow-ground" versions which were my "best" blades.  They haven't been cutting well for some time and recently started burning so I knew it was time for replacement.  I had no idea where to turn so I spent some reading reviews on Amazon.  After stumbling on these Freud blades, I decided to give them a try based on the overwhelmingly positive reviews from other users and the fact they didn't cost a fortune.  I ordered three different thin-kerf designs including the combo, glue-line rip and negative rake miter.  So far I've only used the rip and the combo blade but am completely impressed.  They are much quieter than my old blades and leave a beautiful, clean cut.  They also glide through the material easily without leaving any discoloration.  I wish I found these years ago!!  I wouldn't hesitate to purchase them again.
