Quick sharpening question

[larry44]

I have a DEK1. I know hand sharpening is best but I'm not capable of that. I own a Ken Onion Work Sharp. Should I touch up the blade at 15 or 20 degrees? Thanks for your suggestions!

I’m thinking 20 degrees is the better angle for this kind of knife.
15 degrees is too narrow and more for kitchen knives.

Thanks for the reply; I knew the edge angle but I also read that Nathan hand sharpened an additional 12 degree secondary edge (did I say that right?). Will that make a difference or should I just touch up at 20?

Thank you!

If I may , I’d suggest a spyderco sharpmaker kit. For quick touch up on their ceramic stones. I use this on mine and works great. It’s very easy to use

Nathan has specifically recommended NOT using any dry belt sander type sharpeners (the KE WS falls in that category).

The issue is that they very easily overheat the very edge (the sharper the edge, the less material to absorb the heat from the friction). This would negatively impact the Delta heat treat they developed specifically to enhance edge retention.

If you don't have the skill for hand sharpening, as recommended, a Spyderco Sharpmaker can be used to touch up the edge.

I sharpened up my DEK1 last night with my Wicked Edge 130. I recommend Wicked Edge.

If you can't sharpen by free hand, I would recommend a guided sharpening system. I know this is just personal, but I'd stay away from powered sharpeners, save those for your lawnmower blades. A fine cutting tool like a CPK, especially with a thin edge like I keep mine, needs a good hand sharpening.

I appreciate your advice.

Please don't use powered sharpening on a CPK. The Delta protocol's one weakness is heat.
