Thrown weapons have no attack box

I'm trying to understand how thrown weapons work. I have a weapon definition:
Code: 
name			knifeT #THROWNED
type			none
subtype			weapon
nolife			1
lifespan		4
remove			1
gfxshadow		1 1
noatflash 		1
flash			noflash

anim idle
	attackone 1
	fastattack 1
	jugglecost 5
	forcedirection -1
	hitflash bloodhit
	loop	0
	delay	1
	offset	25 27
	bbox 	16 25 19 3
	hitfx	data/sounds/Cutter.wav
	attack 16 25 19 3 8 1 0 0 10 12
	frame	data/chars/weapons/knife07.gif
	sound	data/sounds/Whoosh.wav
	attack 16 25 50 50 8 1 0 0 10 12
	frame	data/chars/weapons/knife07.gif
	
anim fall
	landframe 9
	loop	1 1 9
	delay	2
	offset	25 27
	sound	data/sounds/Clash.wav
	frame	data/chars/weapons/knife00.gif
	sound	data/sounds/Whoosh.wav

	frame	data/chars/weapons/knife01.gif
	frame	data/chars/weapons/knife02.gif
	frame	data/chars/weapons/knife03.gif

	frame	data/chars/weapons/knife06.gif
	frame	data/chars/weapons/knife07.gif

I can throw the weapon easily enough using throwframe. However the weapon never hits anything. I can see it has a bounding box but it doesn't appear to have any attack box when using the debug tools.

It seems I'd forgotten to put
Code: 
load	Knife				data/chars/weapons/knife.txt
load	KnifeT				data/chars/weapons/knifeT.txt
in models.txt which seemed to cause it to use the knife entity instead of knifet entity when thrown and knife didn't have a hit box. Roughly working version of a knife you can pick up and throw for future reference

The knife weapons delay is less than a second , so the hit box disappears immediately,  no? Also it's loop is set to 0?
Wouldn't you want that to be set to 1?

If I understand the stuff I've copied correctly it throws the built in "knife" engine projectile off screen because it's properties aren't very configurable. It then uses throWeapon to generate a new projectile of "knifet" type. Because the animation sets an attack box but never clears it then the attack box persists for the life time of the projectile. Basically loop 0 means that whatever state the entity is in at the end of the animation it stays in that state till a new animation is played.
