Oh sorry Rich. Against the S5, NO comparison. Tali all the way, unless I didn't want a blade the size of the Tali.

esee 6, don't have one but I do have a Scrapyard S6.

Now, to me, the decision becomes more difficult. The S6 can suffice as a fighter OR a survival blade. Shorter than the 711 and Tali yes, but the blade profile... Well to me it's more akin to a fighter, but will work as a (Once again) light chopper. Just tie a lanyard on it and use a couple or three fingers on the handle and it will do most of what you need.

Now mind you, I DO NOT have any heavy or long term use of these knives this way, just a quick and dirty "Hummm I wonder how it would work if I....".

No brain cells were actually harmed in these observations.
