IMO just like there are different blade shapes for doing different jobs, there are different thickness knives for doing different jobs.

I love my DMCG however it is NOT an all around knife, I much prefer my YKCG for that.
My favorite bushcraft knife is still my 80 or so year old marbles woodcraft. It has everything most people doen't want in a bushknife nowadays.
It's carbon steel (relatively soft by todays standards) relatively thin bladed and short with a leather handle and sheath.

For plain come what may having fun I think the DMCG can't be beat (never handled a dogfather though)

Funny I have a fro and in my younger days I used it to cut shakes, funny I never thought of it as a knife with a 90 degree handle before. Makes sense

I like both. Have a BAD and its a great little knife but I also like this Game Warden.

Thickness is something, length is another thing...
Cannot replace one with another and cannot compare them. You can't chop or baton or cut through wood or anything else which is more than double in thickness than your knife edge length, regardless how thick your knife is. An axe can do that because it has different geometry, but a knife can't.

PS: I edited my previous post, adding an advantage for thickness that I had previously forgotten: thicker means better in wood splitting.
