Ever since my wife bought me a Ka-Bar I've been wanting to start collecting classic military pattern knives. So #2 in the collection is a Fairbairn-Sykes by Lewis International. What do you all think of this pattern? Of course it has obvious weaknesses, the main one being fragility. But it seems to me that an ultra-light blade like this could have some advantages in a fight and many in sneaky WWII style sentry removal. But frankly, I've read Kill or Get Killed by Applegate, everything on gutterfighting.org, and I train with training knives frequently and I cannot see this knife being used in serious combat duty. Am I wrong? If so, why? I rather like the knife but it just strikes me as being a little too light and fragile.
