Sheath looks good and leather is quite thick. The strap retains the bowie well and releasing the strap is easy.
In hand the blade seems kinda large but is very light for the size. If one looks carefully one can see where the spine is tempered differently from the color. the handle is comfortable but the wood is nothing to shout about. I'd rehandle it in a different wood or micarta or even G10 someday. The guard is crazy thick and very solid.
Spine is not too thick. You can check out specs in websites for accurate details. For me it is just right and too thick will result in it being to heavy cause this blade is kinda long and rather wide.
Tip is very strong. The reverse edge is sharpened for back cuts.
I have taken this blade chopping in tropical rainforests and it chops quite ok in dense tropical woods. The edge is hardened quite well as I've taken a bastard file to it to check the hardness. The tip stands to stabbing and prying when I tested it on the dead trees.
Hope this is helpful
