I'm trying to sharpen a drop-point knife (benchmade griptilian). I use a work sharp guided sharpening system with angle guides and am trying to follow the 20 degrees per side recommendation. All the manuals and instructions suggest I rest the blade on the guide, but I don't understand whether I rest the bevel or the "body"?

According to the images should the green
green
or the red
red
part of the blade "rest on the guide"?

    Just a guess so not leaving as answer but I would imagine red. Sharpening is about angle relative to vertical and so since different knives have different bevels I'd imagine it needs to be secured from a "true" vertical.

  • I have the exact same knife I sent it back to Benchmade to get a new clip and they also sharpened it and sent it back to me for free.

The angle is measured from an imaginary line that goes through the center of the blade from the spine to the edge. It is assumed that the top part of the blade (in red), is parallel to that line. Therefore it would be the red part of the blade that should be flush to the guide. A pro tip to check if you're on the right angle is to use a permanent marker and color in the fine edge. It will result in a thin black line on your secondary bevel (assuming it has one, most do) which is the very edge of your blade that you're trying to sharpen. Then when you sharpen, you'll immediately see what part of the blade is in contact with your sharpener and if you're at the correct angle.

If look at the demo videos or read the manual on the webpage for work sharp sharpeners.

It seems pretty clear from the manual alone, that it should be spine of the blade against the angle guide, with the cutting edge down towards the grinding part of the tool. This will allow the cutting edge to be at the correct angle relative to the grinding part of the tool.

  • Sorry, i should probably clarify - i'm using work sharps' guided sharpening system and i wasn't able to find any exact specification whether it should be bevel or spine

  • @HardLuck can you add a link to the product and/or manual, so that others can see what is going on? I searched using your original post terms and found the one in my answer, but if you can provide a link to the exact item, that will dramatically increase your chance of getting an answer.
