    Making reasonable pictures with an USB-Microscope takes quite a bit of practice, so that's what i'm doing at the moment.
    The idea for this thread is to show some pictures of untouched factory edges from various brands, so feel free to contribute if you have some as well.
    This is the first one, a factory edge with a buffed apex on a Spyderco Paramilitary 2 in CPM-S110V steel and a measured edge angle of 30 degrees inclusive:

    Lenox Gold bimetal utility blade with titanium nitride coating on it's edge, which also has a microbevel.
    The edge fits in the 25 degrees inclusive slot in my Tormek WM200 angle master.

    Factory edges are mediocre

    I examine the edge, under magnification, on any new knife that I buy and I have yet to find any (except Rockstead) that are impressive. Most are about a 400 grit finish. I use a Wicked Edge sharpener when I decide to keep a knife and bring it up to a mirror polish - about 2000 grit. This makes a cutting difference that is hard to describe, basically incredible.

    New & unused Leatherman Wave 420 steel blade from around 2008:
    The edge can hardly cut copy paper due to a rather large burr.

    New & unused 420HC blade made in 2010 for a Buck 110, and the edge can shave armhair.
    The first picture was an attempt to get the lens as close as possible to the point of the blade, while at the same time trying to focus as best as i could, so this is about the maximum enlargement.

    Thank you for doing this. Very cool stuff. Makes me either want to buy one, or send you some blades that I sharpened (Wicked edge) to see how I am doing.

    Can you post pics of a factory (before) & Wicked Edge (after)....same blade?

    Edit: You encouraged me to sharpen an Ultratech I recentlyour acquired. Took it from 100 through 1600 ceramic. Sharp as hell....at least I think so. Need one of those microscope things! LOL

    The tip on that Buck looks like a melty ice cream cone on a hot day at a county fair, visiting the sad blades booth.

    Thanks so much for the pics! I need to get one of these. I can see where it could help you take your sharpening to a whole new level.

    What about a not-so-factory edge?

    That is a great gadget. The image quality looks pretty good. Can you tell us the brand of microscope and magnification used for these photos? Thanks.
