    3M Diamond Microfinishing Film Sheets 675L?

    Anyone ever use these diamond sheets for sharpening or stone flattening? I heard that you can stick them to glass or aluminum plates.

    Other companies sell this stuff too. There's a whole range of grit sizes available.

    I've posted a picture of this stuff in 3" wide roll form but you can get it in sheet form also.

    I have not used them personally, but I know others have used 3M film on razors with great success.

    A coarse enough sheet would make a very inexpensive flattening stone : example

    I'm interested in this too. Last week I was looking at those same sheets but passed.

    Would these sheets be used for final stropping?
    I just noticed that my local Lee Valley carries this product so I'm very interested as well.

    I agree and even better is than what you drew up is that you can get this film in PSA format so no double sided tape would be needed.

    Yeah I've heard of them being used with razors and also plane blades too.

    I like it and I think it is pretty popular with jig system users.
    IMO Silicon Carbide is more aggressive and Aluminum Oxide leaves a smoother finish.
    Diamond is the best but costly and harder to find.
    Prices can vary a lot, I get mine at toolsforworkingwood.com (no diamond)
