work sharp questions

They work well with knives. As far as a shovel or machete you better off getting a bastard file and smoothing it out and then use a work sharp. The circular work sharp designed to sharpen chisels looks to be a nice produck but i dont have experience with them.

They shine with Carbon Steel knives. They get my Old Hickory's super sharp.

i have one, don't know how to use it really

My dad did a couple of my hand plane blades on his once and they came out sharp as shite. I was impressed. Never tried any other tools.

Should be a sticky for this topic.

WorkSharp Ken Onion edition with the 18" belt blade grinding attachment and a few aftermarket leather stropping belts. That's all you'll need for any pocket, hunting, or kitchen knife. Easy to pick up free-hand sharpening and you won't grind off a sharp point. Axes, machetes, lawnmower blades, etc. I use my old WorkSharp since the thinner belts and lighter weight make it easier and the coarse abrasive will remove metal plenty quick. Chisels and hand plane irons I use 3M wet/dry paper to 3000 grit on the kitchen granite counter and finish on the WSKO with a green compound charged leather strop.

I have a Work Sharp as well as a Spyderco Sharpmaker. I get better results with the Sharpmaker with knives. I use the WS for mower blades, shovels, etc.
