.... I know my next one will probably be a bigger one.... I do a lot of limbing and such (I cut mu own wood for my wood burner and in many cases it looks like a khukuri would be easier to use to limb a felled tree than my chainsaw. So, in that case I might be looking at a bone cutter or something else. Anyone have any suggestions on what I need to look for next. I think I can handle something bigger (I'm 6' 3" and 270). At one time I actually wanted a full sized axe head on 15-18 inch handle. But now that I've found the khukuri, I know that one of these will do what I want.
The main HI web site doesn't show all the models, sizes and variations that are often available. I suggest that you spend some time browsing threads on this forum to get a more complete picture. The threads within the past year or two usually have pictures. Some of the older threads have had the pics removed, presumably because of space limitations.
If your hands and arm strength are in proportion to your size, you should be able to handle an 18" AK, CAK, ASTK or bonecutter with no trouble. All of them are certified for the kind of use that you describe. You should also pay attention to the weight and handle size. Yangdu always posts weight as well as length in her DOTDs.
Some people like even larger, heavier models. They seem to satisfy a primal urge, perhaps stemming from the days when we had to worry about saber tooth tigers and cave bears. I have that same urge, but I'm learning to resist it. Unless you're stronger than the "average" 270 pounder, you might want to go for a heavy duty 18 incher next, which would be quite effective in your hands.
That should be plenty for 3" branches, and you'll be able to lop off 1" and 2" branches without feeling that the blade is still hungry and wants to swing around and get a piece of you.
You could always go for one of the monster khukuris later, when you have more practical experience.
