Tenryu recently sent me a few samples of their latest offerings for the Kapex and I’ve been playing with them for the last few weeks. Overall, the quality is exactly what you would expect from a high quality blade manufacturer. How does it compare with the stock Festool blade? My initial non-scientific tests showed that the Festool blade produced a smoother cut on 8/4 bubinga. I tested this by feel and by rubbing the endgrain with chalk to observe the surface imperfections. Tenryu explained the reason for this phenomenon and it has everything to do with the grind on the teeth. The Tenryu ATAF (Alternate Top/Alternate Face) grind makes a more aggressive shearing cut, while the Festool blade has an ATB (Alternate Top Bevel) grind which essentially burnishes as it cuts, resulting in a surface that feels smoother. I also noticed less tearout at the back end of the cut with the Tenryu blades. But given the fact that they have higher tooth count, this isn’t too surprising.

I honestly didn’t do enough testing to tell you one blade is better than the other. But if you are looking for an alternative to the blades Festool offers, its nice to know that these are available. Tenryu already has two on the market and you can purchase them here. I also heard from Tenryu that they will soon offer thinner kerf blades for the TS-55 plunge cut saw (.063″, 52 tooth and be supplied with its own riving knife). They hope to have the blades by the middle of October.

So if you missed Demo Night last night, you missed A LOT! I started by discussing polyurethane durability and glue shelf life and showed some interesting examples of both. I then gave a little feature review of the Festool Kapex. And finally, I showed off the sweet lumber I just received for the upcoming Gadget Station. I then got into a discussion about mail order lumber and the company I have been working with lately, Bell Forest Products. And this is just a small sample of the session that ran about 2 hours and hosted nearly 100 people.

And please excuse the camera work. I pretty much did the best I could by myself. You should notice much improved video and audio though, so that’s a good thing. If you want to attend future Demo Nights, just check the Calendar periodically for updates.

Some general miter saw safety tips including clamping and operation tips. The Festool Kapex makes its first appearance in our show as well. And finally, some outtakes.
