Here is a modified 190 Grain Grizzly.  I based my modifications on Dr. Ed Ashby's post on how to modify them.  

It is 1" at the base and full width at the front.  I put a chisel tip on it.  The tip bevels are ground on the opposite side of the blade grinds.

I also decreased the edge angle and took it to a zero grind and then buffed the wire edge off.  It will now easily shave arm hair!!

Dr. Ashby please let me know what you think and if I did it correctly.  I look forward to your input!

Here is a picture of the modified broadhead and an unmodified broadhead.

Thanks for looking!  I look forward to your input on this.

Great work.

Tom, that looks spot-on!

Dr. Ashby you want to try out a couple of them??

Tom

tom, did you design a crkt knife called the dogfish?, I have one, its a great knife, I'll try a couple of those bheads for ya, cool knife too

Ian, thats me....  Thanks!  Glad you are enjoying the Dogfish!  They are a fun little necker.

If Dr. Ashby gives his blessings, I may try and modify these heads if there is demand for them.

I will have to see how much time it takes, but I don't think it will be too bad.

I have to say that I was VERY surprised when I got the Grizzly's.  The tips are BLUNT and the edges wouldn't cut hot butter!  

Tom

Tom , I am demanding a Dozen of your modified grizzlies. Ok, perhaps Demand is too harsh a word, but I bet there would be a great demand for this modification. However, I would like to put my name in the hat for a Dozen or so of your Ashby/Krien modified Grizzlies, should you start this endevour. Your neighbor in Tejas, Suty

Be interested myself, better a knife maker modifying than a fire marshal with no metal experience!!

Seriously if ya undertake it count me in, I seen so much bout grizzs here lately I gotta try em.

Jdog, You are so correct...better a knife maker than a Firefighter (me). Dallas 20yrs.  Later Bro, Suty

Tom,
I'd be interested as well. Some people just shouldn't mess with grinders...

I would be interested also

count me in for wanting some modified griz.

Tom,
I've got one of your Mid-Tech Dogfish knives and put me in for some modified heads as well.  I like the knife above.  Guess I'll be ordering something else from you, as well as the heads.

Very nicely done, good job.  

Tom : Very nice heads :0) Can you cut the bevel on the other side of the blade for those with left wing fletching ?? That would be very cool:0)  Drew

I was born in Dallas,lived in Seagoville, then in Dad was a Marine that retired back home to Texas but then decided he like coastal NC better.

Let me see on the next one I modify.  I can do it, but it might make the front to narrow...  maybe leave the very front double edged and turn into the chisel grind??

Tom

Tom,
GREAT job on the modified head. Also, great looking knives. Put my name in the hat if you need field testing done too! Just curious, what did the grizzly weigh after mod.?
Thanks
Todd

Tom :  Thats what I was thinking , it would leave the front too narrow . It would still be cool to try it and see , wish I had your skill :0) Thanks Drew

tom, you need to make some more up and get someone to test these, cause I want some, got some big hogs on my uncles land that would give these heads a good test run
