I've recently bought a ginunting from www.traditionalfilipinoweapons.com, and I was hoping someone who has experience with these could instruct me on the proper way to touch it up and re-sharpen it. The edge almost looks convex, but I'm pretty sure it's not, I asked the owner of TFW what the proper method was, but he said I should send it off to a expert for that. I practice with it frequently and do use it as a tool occasionally, so sending it off will become too expensive/not worth it in the long run. I'm thinking I can touch it up with a ceramic stick and when it's time to re-sharpen I could use my water stones. I mean after all a ginunting is basically a machete, so I'm figuring that it shouldn't be any different to sharpen. any suggestions/help would be awesome!
