NAP Hammerknocker Broadhead

More pics to come tomorrow!

 

Those look sweet

 

They do look sweet!

 

Lots that could go wrong there, nothing like adding potential variables that can cause failure.

 

It looks like the tip compresses to force the blades out. Hmmmm........I'll be interested to hear hunting reports when these become available.

The fully concealed blades is a neat idea.

 

Very similar to the original Puckett bloadtrails. There was a reason they didn't make it, too many failures.

 

May have to get some for turkey season

While I don't love every broadhead NAP makes, I haven't ever known any to be garbage. In theory, these should be awesome.

 

This design is garbage.
A carbon ferrule? Really?
A piston type deployment is totally unreliable, as proven with similar designs in the past.
Total junk

 

While I can't comment on the piston deployment; I can say that since probably 95% or more of us use and trust carbon shafts; why not ferrules?

 

Good question.
For starters when lateral force is applied to a hollow carbon shaft it stays intact until it breaks, in other words total failure or fully intact, no middle ground at all. Think about how common broken shafts of any kind are when arrow stays in an animal. The lateral force against that arrow either from the animals movement or the movement of the arrow verse outside objects quite often stresses carbon to its breaking point.
Now a steel or even an aluminum ferrule can also break with lateral force being applied however it's is also very likely to bend and even though it's deformed it will still stay intact.

A steel piston inside a hollow carbon tube is the perfect medium to apply lateral force to this broadhead. But it doesn't end there with this design. The is also the junction of the ferrule to the threaded rod that mates to your insert creating another weak point. We can't over look any head that uses single point blade retention system for each bade that doesn't have redundancy in its retention design.

 

Watching the video this seems like a one and done broadhead. If I shoot an animal and don't get full penetration, pulling out it seems like this would destroy the head and render it useless.

Also, I would love to know if the blades are replaceable?

 

You never know until you try it.

 

Interesting head !! Curious as to how it will perform. Bet it will tear up a turkey! !

 

Chris Hunter from NAP has the first confirmed Hammerknocker kill. Seems like it did the trick!
