Bar Mount chain sharpener

Ok boys I need some advice. I want a new bar mount system. I don't like how slow mine . I have a very old school one kind of like the one in the pic. I also have a 511ax grinder. I can get them sharper by hand. I've seen bar mount guides that the file is seperate. It looked like it had rollers to guide your file. But now I can find it. Lol. Anyway I would like some suggestions please. Also considering a cbn wheel for my grinder. Any thought there? Thank you!

 

Like these? The metal ones will last longer than the plastic ..

I just bought these haven't had a chance to use them yet.

 

Sort of but I was thinking the ones I was looking at had an angle guide too.

 

Another version

 

Yes that's what I'm after. Lol. Look at that. I was thinking it was made by someone other than stihl. Lol.

 

I can't remember the price on them. But most dealers at least around here don't stock them they order them per request
