Anyone know when the new ones will be coming out? I'm looking forward to them. Cheers, Matt
Very very soon. ;)
Just sent a long article on the 'why' and 'how' of single-bevel broadheads to the Gang yesterday. It should be posted just any time now. The Updates themselves will start in September, and there's eight parts coming.
Ok, I'm unpacking and repacking!

Once I read this post, I found the report and started reading.
Once I finished reading the report, I found some broadheads and started thinking about modifying them.
I started with a drawing made based on the description in the report.

That's a 3" x 1" rectangle with a point taper for a 23/64" shaft. I simply located the transition from the tanto point to the large cutting edge by dragging properly sloped lines to the corners of the rectangle. The transition ended about 3/16" from the point. That seems about right...
Here's an unknown arrow knife on the drawing

and here are a couple Ace broadheads:

(I don't like the vented Ace very much; it whistles a little bit going downrange.)
Here are a couple of my favorite broadheads, one for 5/16" shafts and the other for 11/32" shafts:

I the Big ones best... Want to guess who makes them?
I don't have a clue bro....But i just read the Doc's 'why' and 'how' of single-bevel broadheads.....made a believer out of me...i'd love to know who dose make those pictured above...Kirk
Howard hill!!
Yep, Hill heads.
For many years the HH head was my favorite, and I took a lot of game with it. It wasn't until the testing that I found that it has a couple of weak points. The ferrule fade-in is not smooth enough, and they hang up on bone frequently. The other biggie is that they often break on angular impacts, right where the rivet passes through ferrule and blade. Having said that, they are still a better broadhead than most of what's 'out there'.

dr. ashby have you every added a single bevel bleeder blad to a grizzly, eclipse or stos.
would you will get the accelerated roation entering flesh or would the added two blades stop the rotation.
that would be a good experiment.
Brandon, if the bleeder blades are made to work the way they should - thin and fragile, so they'll break away on hard contact - they will need to be single-beveled to match the BH's rotational direction. Otherwise, and they will just be additional drag, and a sizable one too - or the rotation itself will cause them to snap.
Big 5 Broadheads (from South Africa) offer three and 4 blade single-bevel modular (replacable blade) BH's. I haven't seen any of these yet, but the company makes a number of interesting claims in their adds.
A big Grizzly WITH THE RIGHT DESIGN BLEEDER BLADE would come as close as I can envision to an ideal 4 blade BH.
