Wauw, this keeps people busy here...
@JMB: Dude, the second saturday the blades supplied by festool where used and these where supposed to be long enough to cut this thickness of wood
Dude for a jigsaw to work correctly it needs the correct blade for the jigsaw some jigsaws sit higher than others! Mafell sits very low so can have a shorter blade!
So using the same blade does not always make it a fair test a fair test would be that you use a blade that ALL JIGSAWS can use so the blade should ALWAYS come past the work piece when fully retracted up.
The carvex clearly didnt come past the work piece. Saying that im not doubting the fact the jigsaws which might also needed a longer blade still performed with a short blade BUT I wanna see a test with proper use of a tool and having a blade to short for the work piece is NOT proper use of a tool.
@JimB1: Yes it's obvious that you don't do this regularly however, one of the test was to test the limits of the machine. This material is way within the specification of all 5 brands and machines tested. This was a remarkable finding and it was tested again after consulting Festool on whap happened. 2nd Saturday with longer blades and carefully adjusted guides you saw what happened in Rian's post. Im the guy you can hear being absolutely amazed on the bended blade as I was utterly stunned to see this happening.
Anyway I agree with the folks that said using a jigsaw on thick hardwood is something I don't think I've ever done. Usually 3/4" - 1/4" ply is all I use it for. Power to cut though 12/4 mahogany in a jig saw just isn't a concern to me. I have a bandsaw for that
I think I'd be more interested in smooth, tight cuts in ply with good visibility and dust control then power. Weight of the tool would be something that would also be of concern. I'm fairly happy with my Dewalt jigsaw but dust is an issue and I often think a light would be useful. Usually I try to position myself so that my shadow doesn't fall along my cutline but sometimes you can't help it, especially in circle cuts where you have to move around the piece a bit.
So I would suggest like I requested before that to make sure the blade is long enough that ALL jigsaws using the blade in question would be sticking past the material when full retracted.

Interesting since Remco posted this video showing no issues at all while at Festool Netherlands. Seemed to work just fine.
I indeed went over to Festool and tried to cut a 4x4" piece of wood and was successful. You saw my vid on that one. The test 2nd saturday was done with same blade as when I was with festool, blades where adjusted exactl the same and the same blade was used. You saw what happened in Rian's video. I was utterly amazed what i Saw happening with my own eyes especially when we used the 2nd (Brand new Carvex 420) and saw the blade break. Two tests happened within 10 minutes of each other and I was soooo amazed I couldn't believe what I saw. But all of it was true! Bear in mind that the piece sawed in festool was 95x95mm and this piece was aproximately 100x200mm Slightly thicker and twice as wide.
There's one important thing that should not be left unsaid: I couldn't believe it and I wanted to feel what happened myself and I did the same test, I was able to cut this piece of would with a Carvex 420 with the same blade without damage to the machine or to the blade, I did have sparks in the machine towards the end of the piece. Appearantly the other tester just pushed it slightly harder or did something else that make the blade bend and even break. As you can see in the movie it's by no means handled with brute force. He did not mis-use this machine as you probably can see for yourself in the video, this could have happened to any one. As it appears to be the machine is working at it's limit and temperatures end up in a region where they get so hot that it's getting a problem for the blades.

They are using the wrong blade - it should be the 499478
I don't have one here with me but I believe that actually is the blade we used the 2nd saturday. These where supplied by Festool.
Guy's all in all, this post is not to tell everybody that because of this test the Carvex 420 is a bad machine. We tested 5 machines to find out what machine works best. 1 test of the tests that where done was the capacity test and we had a very remarkable outcome that was posted here. Most of the posts now tell that the test is done incorrectly and we are all biased and selling Mafell which is not true by any means. The 4 testers are enthusiastic people that are fully independent of any brand, or any person. We all have very well paid jobs in daily live and share our passion for high quality tools. The test was facilitated by a dealer who'se main machine brand is Mafell, he obviously has high trust in the quality of the Mafell machine as he would probably not run this test if he would expect that the machine he sells would be the worst. I have never seen cheap / bad tool manufacturers run a test that includes high end machines, you can guess why. The tests are however set up by us and not by the facilitating dealer. He gave us complete freedom in what we wanted to test, all blades used or the same throughout the tests giving all brands equal oppurtunities.
Outcome of the test is actually that 2 Festool machines the PS 300 Trion and the Protool JSP 140 (Protool) are very good machines. The Carvex has very nice features and works fine in more regular material for jigsaws than 4x8" wood. It appears to have an issue with temperatures around the blade guides. Far more than the Festool Trion and the Protool JSP. Should we not mention that here? We have reached out to Festool with our results to ask for their opinions before we posted them. So far we have heard that our remarks where received and they are under investigation.
We all have a passion for high end best in class tools and in many many maybe most occasions those machines are branded Festool, in this case it's not, should we than say nothing or be honoust and share this with other tool passionates? Isn't that what this forum is about?
I would challenge anybody to take up the challenge and get your hands on a heat camera and some of these machines and see for yourself what happens. In any material you will cut the Carvex 420 will have a significantly higher temperature around the guide and blades than the other machines. We saw this on 2 Carvex 420 machines from 2 different suppliers, bough by regular Festool dealers in Europe so it would be too hard to believe that something is wrong with the machines.
Will the high temperatures make the 420 a bad machine? I'm not sure, but I do know for sure is that this is something that could be an issue for some of us and for those people it's interesting to know.
Last but not least a reaction to JMB
My test will always be fair like always! I say it how it is CRAP OR GOOD lol
So have we!
