    Well, make them, get after it. Nothing is free.

    It's $250 per hour for SEM imaging including sample preparation.

    Time and money is all it needs, make it so.

    You can cut cardboard with a dull knife if it’s thin. See Nero. See Nero cut...jump to to 35:35 lol.

    I picked up a bunch of cardboard boxes couple of days ago for this test I was going to carry out. Went for a ride earlier, when I came back I noticed it was Christmas day :), so I started the test. I edited the movie, 47min long, I am just uploading it on YouTube.
    I hope you all enjoy the test.

    movie of the testing uploaded ok last night, here is the link. This will show how good M35 HSS is, I could have cut hundred times more cardboard without sharpening it, it is a 'steel designed to cut other steels'

    Stanely (et-al) Box Cutter/Utility knife with ceramic blades would be my first choice.
    Same knife with Tungsten Carbide blades would be my second choice.

    Cardboard can be as hard on a blade as drywall.
