I use my Slimline machete/swords a lot, and sharpen them a lot. I can get them hair shaving sharp after a hard days use. I start out with a rough grit arkansas stone, a rough grit ceramic would do, then I go to my medium grit spyderco triangle ceramic rods, but I use them free hand, not with the sharpmaker guided system. First the edge of the triangle(sometime I will hold the ceramic up and run most of the blade past it, holding both in the air), I usually hold the blade down and run the ceramic over the blade. Then I switch to the flat part of the triangle. These are great for getting precise angles, they help a lot and they are not clunky or heavy. You can whip them back and forth pretty fast when you get the hang of it. It does take practice! Then I move onto the ultra fine grit triangle rod, same thing. I usually work like a foot at a time, but it is all blended together, organic, not set spaces, so it is an even edge and not different per foot. Sometimes between the two triangle rods I use a black surgical Arkansas stone, depends.
If you need major work, I hit the diamond first, then go to what I mentioned above. If I am sharpening a completely dull blade, like making a blade and starting an edge, I use a belt grinder with a makeshift angle guide.
I have tried bench stones, machines, guided systems, etc, and this method, FOR ME, is the most user friendly, easiest learning curve method I have used sharpening swords. And the fastest!
Everyone is different though.
Good luck!
