    I dont think they have a set angle, and is usually not consistent. Most are sharpened on belt type sharpeners, and the angle can change from front to back.

    One other thing that I thought about doing with the Ontario sp1 and that was I'm thinking about sharpening the swedge on it I thought about useing a different angle for it.I think for the swedge I'm going to sharpen it at a 25° angle .what do you guys think about that

    I think it's a great idea, I did just that with mine. Although I free handed it, so I dont know the angle. Come to think, I don't even know if I used stones. I may have used a scotch brite type disc, on a die grinder. It's a quick way to sharpen my larger fixed knives, and machetes.

    I'm have desided to go with the 35° angle it has given me the edge I want and it seems to hold up to the task that I'm going to use it for .as for the swedge I'm going to use a file then switch to stone .in just going to try and keep it a 35° angle also

    The last couple of years, I have been using a Smiths brand knife sharpener on all of my blades. 4 or 5 passes and it's usually sharp again.

    Sorry, none of that answered anything you asked.

    If you contact Ontario directly, they may be able to answer your question though. It's worth a try.

    Terrible picture, but I also filed the spine, for a good, sharp 90° edge. Works great for scraping tinder, or a ferro rod.[​IMG]

    The 90° on the spine was a great idea

    The WorkSharp really does a great job on my carbon steel knives.
