    Hey Folks, I need some advice on how to convex out the edge on a Winkler Knives Field knife. It's 80crv2 or something like that. I have an edge pro Apex that I'm still learning how to use. The grind is a modified convex but I would like a full convex. I am a complete novice at this kind of thing so should I let it be? Thanks in advance for your help.

    You should probably ask the mod to move this to the maintenance forum for better inputs.

    Anyway, there is a video by Wicked Edge to show how to put a convex edge on Sebenza on Youtube.
    I guess you can do similar with Edge Pro.
    Alternatively, sharpen on sandpaper set on a mousepad or something flexible.

    Importantly, You should practice with a cheap knife first.

    Sandpaper on folded mouse pad. Practice with cheap knife first.

    I get a convex edge on my knives by holding my stones in my hand and working the edge back and forth. I used to think a crisp v edge was the best, but since I've been freehanding I'm enjoying my hand convexed edge!

    This is a great way to get a hand convex edge. Practice on a cheapie first!

    If you would like to convex the edge I would recommend not using a backing that is too soft. Too much deflection of the sandpaper will cause unwanted markings on the blade and too much rounding of the edge. A thin mouse pad or thicker piece of leather as a backing for sandpaper is ideal.

    Personally, I use a JRE EMS strop block but as of right now the web site seems to be down. It has a high density neoprene backer with clamps at the end to secure the sandpaper. It made a world of difference in the quality of my convex edges and I was surprised it never became more popular.

    Convex sharpening on stones can be done but it takes some skill with the stones first.

    Should you attempt this? No, not on that knife unless you are ok with messing up the finish and possibly the edge. Most winklers are thick at the edge and while convex would help, not knowing proper bevel geometry or stock removal techniques could result in an edge that performs undesirably.
