Check out the "Woodsman's Pal". It's a derivation of a machete, a brush hook, and a couple of other things. Pretty much a self contained survival tool. If it grows, this tool can drop it.
The Woodsman's Pal is a handy tool. Even a bit more 'all-purpose' survival tool than the already very adaptable average machete. At, OMG they raised the price, used to be >$60, now $85, it is pricey. At that price it better be bloody well outstanding.
Thicker and heavier usually means better cutting on hard wood but tend to be more tiring to use. Thinner and lighter is easier to swing and is handier on light brush and softwoods. That isn't to say a machete can't be used on hardwoods. Some of the toughest wood on the planet come from places where machetes are the most common cutting tool. With patience and the right technique a machete will chop its way through anything softer than the steel.
That said many people who spend their time in hardwood forests, where light brush isn't an issue, or where trees are large find an axe more useful. Then again a machete tip can be filed sharp and fine and used for very delicate work, essentially being able to substitute for a pocketknife. Used to be some remote tribes each family group had a machete as their only metal tool. So it got used for everything from clearing land to preparing diner and delicate art work. Harder to do that with an axe.
I provided a link to the ones I was familiar with. I don't know anything about the CS Heavy Machete. Perhaps they got lazy on the quality of the steel or heat treatment thinking the thicker steel would make up for it. QC isn't always what it should be but, looking at the site, what do you want for $17.
It pays to try gear out and find out if it suits you. I've had people try a tool I got a lot of use out of tell me it was useless. Different strokes. Find what works for you.
