Makes sense although it's counter intuitive to use a file that way.

You don't drag the file , you push it just like you would the way you are used to its just that you file downwards from the outer edge of the cutter .  The saw would be facing the opposite way for the same cutter if you see what I mean .  You might be better off googling it .....

I'll take your word for it but unlikely to need to try it myself

You can buy files similar to that already . Files for sharpening square ground chain . You are supposed to file from the outside inwards as opposed to inside outwards though .  They are hexagon , double bevel and a goofy .

 

Ah I thought they were only trianglar/double bevel and goody - but I may be wrong.

With respect, just because you can't find something on the net, doesn't mean it could be granted a patent. I'd go as far as to say that a patent for a hex file probably wouldn't be granted (if the hex was the only point of differentiation).

 

Yep you may be right - but I would expect a company like Stihl to be able to make the product so that it is patentable.

 

Only because they prob have a lot of experience with the patent process and the resources to get them and enforce them. As in they can 'build in' something that makes the system patentable.

 

And in many ways IMO it's fair to do it as otherwise where is the incentive to come up with these sorts of new tools..

Completely agree. They could engineer a novel idea into the design that would make their product patentable, but that idea can't simply be that the file is hexagonal. 

 

Patent or no patent, it will take days for a boat load of knock offs to leave China.

Squre filing is tricky as you can easily beak the cutters which isn't good, this system looks like it generates a constant cutter angle, with no need for operator skill. I also like the little marks on the rakers so that once you have reduced them you can reshape them correctly too.

The more you make stuff idiot proof the better in my opinion.

The files will have to be an exeact size to get the right shape, I guess Sthil will just make them in a wierd non-standard size to get the consumer stuck with buying them. Then give it a wee bit and they will get copied in China and cheapo ones will be available, low quality made of Chinesium !

.... I'll put money [but not much] that it's the file that does this and the chain is the same as standard chisel [or rapid super as Stihl says]. But out the box it will look different.

 

 

 

 

Ah now I watched a couple of times I don't think it will be the same - as this area of the tooth needs to be right from the start or the flat part of the file will not sit correctly.

 

I lost my little bit of money I put on this I think! 😄

Turn the file 60 degrees and file the bottom out, then turn it back and proceed as intended.

To be fair, 10 quid a file is going to put me off though.
