bigmothertrucker,
The kukri you listed is a little high in price. Look at
http://www.ltspecpro.com/39lgk.htmlsame shape and weight,different steel.
As others have already stated the Kukri Machete that Cold Steel makes is very inexpensive, durable and if you stay on the site for the link above you will find it.
My suggestion is the 13 inch blade model (Kukri Machete). For this price you can buy one and see if it works for you.
Also, take a look at the special forces shovel. You can sharpen the edge and have a workable ax while actually having a shovel/e-tool.
However, a 4-5 inch fixed blade knife should allow you to do all the stuff you listed in the pros and cons.
.Use baton and knife to chop/splitwood
.Use knife to make digging stick
.Use knife more efficently.
Just a few thoughts.
