Note : This is the First Test done for the benefit of the Hunting Lodge.
* Hope it helps
___________________________________________________________
Tight point (makers of the T-lock) came onto the scene last year with a big Buzz from many experienced hunters.
I (as usual) kept my feelings to myself as much as possible, although I had to say (on a few occasions) that this was the blade design I most favored on a physics basis.
Soooo.....
Today was the test and although I have to wait an hour before I pick up the film , I can still write out this report and post Pics later.
For the test I use three mediums.
First , to check for weak blade design consistent with being able to hold an edge , I use a Rinehart block target.
This is shot until the blades no longer hold a cutting edge and a scale rating then applys.
( compared to that of the best and worst heads tested .)
(Plus judgment call +/-)
Second , the torture test.
A 1 1/2" block of green pine board is shot
and then the head is extracted to check for damage.
Last , the shoulder test.
The shoulder section of a large game animal is blocked except for the area where the maximum Mass of bone is located.
In this way , the shot will hit the block if it does not hit the bone.
(also gives me a good aiming point)
On top of these three , there is the flight test.
Heads are tested at maximum stress levels and speed is also at the top tier.
The BK2 launches a 315 gr. arrow at 325f.p.s. which is 45fps over the norm in the field.
(lets keep this point in mind)
77# of K.E. is generated and I have not gotten (and do not need to have) a down range K.E. for these tests.
All shots are at 30yrds. to reflect maximum energy loss in most hunting conditions for the northern and southern states.
(sorry mid west guys
)

And now the results
Flight :
These heads held together in groups perfectly and in fact after the second launch I put up a Vegas 3 spot for fear off chopping my arrows apart.
But......
wind sheer was evident as the broadheads hit 6" high with one blade (of three) up and 6" low with two blades up.
Turning the two blades outward from the riser made the most awesome hook I have ever seen shot but they were consistent. 
I brought 4 other Proven heads out to compare their flight (as I always do) in case there is an error with the bow/shooter ....but all 4 of these other heads flew as true as if they were being run down a laser beam.
I generally do not do this but I did bring out my slower Reflex Grizzly to see if it was just the speed that they couldn't handle and sure enough....they were on spot.
I am only guessing at the grizzlies present FPS but an educated guess would be 270fps.
So thats the end of that .
---------------
Next was the block test.
Nothing proves out a metal faster than foam or paper as far as the metal being able to hold an edge.
Now this is where an educated guess comes into play as far as the detriment to the edge.
You have to compare it to other heads that have scored 10's in the past.
By the 4th shot the blade was dull enough that I surely would not have hunted with it.
Best to date was 16 shots
Thats a 25 rating
End of story
-------------------------
Next was the Pine Board torture Test :
The head made it 3/4 of its length into the board before coming to a stop.
This was awesome performance comparatively and most make it 1/3 of their length for standard 3 to 1 ratio heads and 1/2 way for the 2 to 1 ratio heads.
This at least proves out my theory of the superiority of the scimitar design
But.....
After careful extraction , one blade had broken off at the upper third and another had sizable dents
IMO....metal needs to be worked on... be it in the form of a thicker gauge (Uhhhh) or higher grade (yeah)
The Ferrel was outstanding and suffered nothing
(I think it actually made it shinier ;D)
The end
-----------------------
Finally!....the real test
Because of all the hype surrounding this head and my own desire to see the scimitar blade succeed , I took one of my Private Stock Boar shoulders out to the block
Being the bad boy of the animal kingdom here in the states,I wanted to put him up against the new kid on the block for a one shot show down
I had one new head left from the three pack and wood all around a 4" window at 30yrds.
The drift I had re-sighted for but my nerves were frayed with the thought of blowing two shots and not being able to finish the test until replacements were delivered.
So with a deep breath I settled the pin into the slot and slowly tightened the index over the trigger as the exhale began.
Without warning , the arrow was off and my heart was in my throat
The solid crunch from 30yards out was music to my ears and I happily hung up my bow and scooted to my prize.
Perfect shot!
I skun out the shoulder and washed it down in the sink as my wife fairly bounced off the walls,yelling ............ "GET THAT THING OUT OF MY KITCHEN!!!"
;D
Well the entry hole wasn't the largest or best I have ever seen but it'd kill ya'
The bone was split three ways with a perfect center shot and no glancing blow.
(Love it!)
Total penetration was 12" with a 1" foam board backing to reflect the internal resistance.
It would have killed merely by the 12" entry but never would have made the other side.
Blade damage was Massive!
Although the blades did stay intact (unlike the board test head) the blade edge looked like it had been shot through a gravel bank out of a high powered rifle ;D
(Gotta' work on that metal)
The blades would -in no way have- cut any blood vessels which could have been pushed aside.
The Ferrel on the other hand looked awesome!
(good job! - not an easy feat or often done anymore )
-------------------------
Bottom line
Not a head that I will suggest but one that has a great future in front of it with some refinements
