I have an ESEE Lite Machete, which is essentially an Imacasa with an ESEE G10 handle. I also have an Ontario 12" thick blade that I favor for general work. The ESEE/Imacasa is more for bush work. I've just run across an old 14" Tramontina bolo that is of thicker steel like the Ontario 12", plus it doesn't have the bit of hollow grind at the edge the Ontario does. So, I can get a full convex grind on it. I'm looking forward to tuning it up and testing. It's kind of an in between blade that might suit my needs.
If you're experimenting with grinds, consider this multi-grind concept. The idea is to make the machete into a true multi-purpose tool. There is the standard convex edge, a scandi edge, a square edge and a rounded edge. This first video describes what the edges are for. He has other videos that cover the actual mods and general machete use. I was thinking of producing these at one point.
Without a doubt, machetes can't be beat for utility, especially for the money.
