I did use the new Carvex blades in the PSC 420 for all of my filming but I have used the old Trion blades and they work fine. The blades are different; the Trion are slightly narrower at the back of the blade and the Carvex ones are rectangular in section. I am sure that Festool intend people to use Carvex blades as they have just introduced them but if you have any of the old Trion ones and no Trion to use them on then give them a go and see how you get on - I had no problems at all.

Hi Peter,
with the Carvex blades the cut was a lot better. One of the things that I noticed though is that the Carvex blade looked bent when looked at from the front.
I removed the foot and saw that there is an clamping screw that,when loosened, lets you move the entire guide assembly. After a few attempts I got it perfect.
The PS 420 is now well within my expectations, even in 7 cm wood, very close to the PS300, and thus a keeper.
Actually, the carvex blade made the PS400 a lot better as well, even though one cannot tune the guides as they are fixed to the machine.
