    Hey all,

    I’m wondering what scope anyone / everyone uses to look at their knife edge to monitor sharpening progress. I’ve got a cheap loup that works ok, but I hear (and see on YouTube videos) that those $20 scopes are damn nice- at least good enough to see edge blemishes and I’ve even seen want I believe ate metal inclusions. Amazon and eBay and gearbest and bang wood all seem to sell a 10-30$ unit that even takes photos, and I’m interested if anyone has bought one recently, can send a link or model with a quick review. There seem to be so many options!

    Ideally I’d like to broadcast the video to my iPhone, but not opposed to hooking it up to the usb in a laptop either. Some of these units claim rediscutions magnification and I presume it’s not a lot more than a simple webcam type thing. One nice feature I think I want is something like a shroud beyond the lens, with internal led lighting for the camera, that will allow me to maintain a consistent focal distance from the blade edge.

    The ability to capture a decent photo would be cool, and if I ever decide to take on a side-hustle of becoming a pro sharpener, I could snap before and after photos for clients! But, this is really a tool to visually monitor progress and supplement the “feeling for a burr” approach.

    Anyway, all input is appreciated and thanks in advance!

    Most people won't know what their looking at or care what the before and after pictures look like they just want sharp.

    If you don't have a jewerlers loupe I would get that first for portability, simplicity, and no setup time or anything else to worry about.

    For a digital microscope their not used often here except by a few and camera technology keeps changing so this probably isn't the best place to find info on what to get. Your probably better off tracking down reviews and finding a forum where their used extensively.

    Yea, I get that it’s not commonly used, and yes I’ve got a cheap loup as I mentioned, but I’d like to just put up the camera / scope to the edge and loom at scratch patterns and edge apex/defects to ensue m good to go to the next grit.

    If another forums may be better to have this topic, please suggest.

    I have seen a number of posts here about scopes, but no one really recommending this one or that. Yea, for $20 it’s worth a risk buying from one of the Chinese sights like Banggood or gearbest but I’d really like to get some sharpeners opinions on focusing depth of field, lighting, and what everyone’s experience is etc...

    Cheers

    No idea which forum, or else I would've mentioned one though I imagine have one with a good light source would be a must. Or a table lamp to create a light source and maybe a privacy glass sheet or something along those lines over it to play with to see if that helps with with not creating glares or I may be over thinking things.

    Something to hold the knife steady would probably help too with holding the blade steady so you can get in focus and get a good photo. Lighting and ability to keep the blade steady would probably play a bigger role than most other factors.

It cranks out its own WiFi signal to deliver higher resolution than BlueTooth. Other lenses are available for other magnifications.

    Be patient, there are some guys here that take amazing edge pics at extreme magnification.
