I would think that a forged ax would be a better choice than a cast one.
It seems interesting that the sheath would he 50% more than the knife. I would personally go for a little heavier duty knife.
Not saying these are bad items, but I just think you could do a little better. I think the knife would be great for light duty work like patch knife, cleaning fish, etc., but for general duty, a beefier one would be best.
