i got a LMF II ... best knife i have ever bought ... i have abused it like hell ... and its still as good ... i have that and a BK2 ... use both for woodland work but the LMF also sits with my BOB ready incase of a more urban scenario
I got the LMF ii - very functional knife. It has a pointed butt end for breaking glass or a skull breaker. You can lash the knife to a piece of branch to use a spear. The sheath can be mounted in several ways and molle compatible. Sheet has built-in sharpner. Blade is sharp and partly serrated. I love this knife.
I also own a kukri - full tang. I bought in Nepal. I have used and tested this to cut down branch around 10cm thick. It has a double edge and very well balance and very sharp. It is more on the tactical category though unlike traditional kukris.
don't listen to the people who are telling you to buy a ka-bar over a gerber lmf2.
I currently have an lmf 2 and two 2 ka-bar knives. the ka-bar is a great fighting knife but impractical as a survival knife.
the Ontario stuff is good also... but is too over rated in my book. the only real plus for the Ontario stuff are the micarta handles. I have an rd6, which is a good knife, but comes with a crappy sheath. so, unless you buy Ontario's more expensive brands (esee, rat) you get a crappy sheath.
the mora classic is one of the best blades in the group but it has a cheapo wood grip and doesn't have a full tang.
of all the knives suggested I would personally go with the lmf 2. it has a good blade, nice comfortable grip, good usable features, a built in sharpener, and a good quality sheath.
the ontario stuff is a close second, but they are simpler knives and don't have the features of the lmf 2.
Bushmonkey makes some sweet lookin ones out of 01 using blanks. Never seen a sheath for em though. For a multi use knife you can depend on, the lmfII with molle sheath would be hard to beat for the price. It's not as sexy as some other blades for sure but I like the ability to quickly make it into a spear tip which practically 99% of knives lack. It's not a $200 blade so it would work well that way I'd bet.
