So I'm going to spoil myself with a 'new' vintage axe-head off that auction site, or maybe even push the boat out and get two. Any thoughts on what makes a good axe-head for roughing out bows? As I carve equally badly with either hand, swapping when I get tired, is it worth going for both a right-sided and a left-sided hatchet, or does one well-shaped and nicely balanced head mean there's no real benefit to a 'handed' axe? Also, straight-edged blade, curved edge, flaired points (fishtail) or bearded? And finally, how heavy - this is a shaping axe not a felling axe, so big weight is probably a no-no, but how much is comfortable to work with but still heavy enough to do the job? Any/all advice welcome! Thanks
