For those not in the know, (and for improving the searchability of this thread) these are the "chakra knives" used by Asuma-sensei (and also Shikamaru) from Naruto.

Great tutorial as always. I might have to get ahold of some comic backs and see what I can do with some of your new techniques.

Spoilers regarding newer chapters of the Naruto manga:I feel as though I should make some of these, if only out of respect for the guy. Man, that really sucked.

I cannot for the life of me get a hotglue gun anywhere! Is it at possible to sustitue a hot glue gunfor something else. Not pritstick or anything, but PVA or superglue?

Not really. For gluing cardboard together, other types might work. But in this case, the hot glue is also used to fill in the corrugation of the cardboard. I don't know what PVA is, but if you choose to use Superglue, you will need dozens of bottles of it to fill it all in... if it works at all. I really don't think that Superglue will dry in a solid block like Hot Glue does.

Thanks FeatherWeight! I'm gonna start on a pair of these for my Shippuden Shika cosplay right now.

If you can get the hot glue sticks you can melt the tip on a candle flame. It might take a little longer than if you had a glue gun but it should work. You'll just have to be a little more careful since it might drip and also don't hold it over the flame for too long 'cause the glue will burn, give off an awful smell and turn black (and will also dry black instead of semi-transparent)

i think the hiphone is not really worth it to buy, because alot of things that you can not do with it.
