Tantos are cool. I’d go for the short tanto version.
If “classic is classic” is the line of thinking here, might as well go for the full-sized version.
I agree with this.
If I wanted a show piece then I'd go for full size USMC with stacked leather handle.
If I just wanted something I'll potentially jam into someone - tanto.
I mean, if he's going for kraton handle and short blade then he may go for tanto tip too, if it's already different then it may as well be completely different, at least it's more unique.
I would say a blunt impact instrument would be a better choice for home personal protection.
As someone who fell off the tree, bike, had an axe with piece of wood on it break off and hit me in the head, had bottles broken on my head, plus got punched into face more more than once - I would say otherwise.
My head is a bit bumpy, I do have few small scars, but none of these things took me out instantly as people tend to believe it happens.
With dull weapon you're pretty much screwed if you don't hit attacker's head, unless you have serious weapon that has capacity to break bones, such weapon is also likely two handed and he'd need some space to take a swing, and from looks of the thread, this guy is in narrow space.
What are chances he'll hit the attacker into the face if he just woke up, is scared and is in the dark?
With a knife, he'll do some serious damage no matter where he hits, they might not go down fast, but they eventually will. If nothing else - police is going to track them down more easily.
