I have heard (here) that Stos was coming out with a single bevel broadhead. Does anyone have any details? weigths, dimensions etc, When will they be out? Thanks,,Frank
Wondering the same things Frank. I saw in the latest TBM that Stos had changed hands and that Magnus will continue to build them and that a single bevel was in the works........no other details though. Mike
Yeah I too read about the change of ownership and the possibilites of major improvements. If STOS makes a Teflon coated single bevel broadhead in heavy grain weights (160,190), they will be producing one of the world's most deadliest broadheads. I hope they come through, count me in for a couple dozen! T
I tryed to check it out also but there web sight would not come up. Maybe do to the new ownership thing.?
We were notified a few months ago that STOS had changed hands. The new owner (Todd) was talking about the changes mentioned in TBM at that time. Sounds like some great ideas to me.
It might be a little difficult to pull off quickly IMO however. As you know STOS heads are subbed out to Magnus. Magnus does not make many heads in 160 grain and none over that...nor do they use Eclipse style teflon or have a single bevel anything...so there could be some work to do there yet to bring it to fruition.
I hope it all comes together soon as STOS are some awesome heads already. :thumbsup: I believe I'd welcome a chance to head into the woods with a 200 grain left single bevel STOS!
Tim,
I would like to see it come around too, but Tim is absolutely right. It will be difficult to pull of quickly since the new owner will be relying on Magnus to make the changes. Time and and patience. dino
STOS are great already. I use tanto-pointed 160gr. and 130gr. almost exclusively, along with a couple old Eskimos. single bevel could indeed be greater, according to Ashby. 2 questions:
1.I use LW feathers. would they make STOS Left and/or right bevel?
2 could single-bevel STOS please come sharpened already, for people like me who are incapable ( or not willing) to learn to use a file and can't stand the Lansky kit?!? :mad: :D
I agree with Alex. The last bull elk I shot was with the 160grain STOS, full penetration and the bull went down in seconds. That being said, I would welcome the improvements that are being talked about. Patience is a virtue. T
Todd is a friend of mine. I'll let him know of this thread and if he's available maybe he can shed some light. Mike
I'd rather see a heavier version of their current heads, I'm not a fan of the single bevel, mainly 'cause I can't get them sharp!!! ;) :)

When shooting a SB head-the grind should match the helical. If shooting a right helical the right side should be ground and vice versa for left. Sharpster can probably give great advice on sharpening the SB and DB heads.
How about a 160 STOS with standard bevels and a great bleeder?!!?? Now to me, that would be the perfect broadhead :readit:
Yep, thats what I was thinking. A teflon coated normal bevel STOS with a bleeder would be the perfect head!
I'll vote for adding a bleeder blade....a long time coming...hope it happens.
What's the difference between the stos and the grizz? The physically look the same except for one has a double bevel. If they change it to a single bevel, we have another grizz! lol
Mr. Chuck Ummmmm........ Perhaps you should take a closer look. There are design differences. On the other hand there are a limited number of things to do to make a singleblade/two edged broadhead> If all we had available were Magnus, or Zwickey or Ace or Eclipse or Tuskers how much difference would it REALLY make?
mr chuck...I believe the grizz is 2 thicknesses of steel stamped to make the ferrule and bonded together...the stos is 3 pieces, one blade-center, and two stamped ferrule pieces, so the point of a stos is actually 3 thinknesses instead of 2. never put a micromiter on either a stos or grizz but would suspect the stos to be a bit thicker on the nose.
And the STOS is wider also.
I have used STOS heads and like them. I want to plead some ignorance - why a single bevel?
Frank X.
Dr. Ed Ashby's research shows that single bevels split bone more effectively....which makes some sense when you look at the end on profile of a 2edged broadhead sharpened on each edge with single bevels. There is a transference of forward motion into rotational torque as it penetrates. Whether this is reason to abandon the double bevel heads that have worked for thousands of years is up to each individual. I'd buy some single beveled STOS heads.... but I'm not worried about using the old double bevel Zwickeys, Ace, Ribteks and Razorheads in my stash.
I recently spoke to Todd about a bleeder blade as the packaging has a compartment for them. He told me they are coming out with a teflon coated single bevel this year but as of now there are no plans for a bleeder blade. Maybe down the road. Greg
Frank X, the single blade as Dr. Ashby's design is wicked sharp because by leaving one side of the edge flat and grinding the other ti about 25 degrees. A good bit finer edge on a long broadhead - really slices instead of chops. I killed my first deer a couple of weeks ago with a 150 Grizzly El Grande ground like that - it didn't hit any bone (actually just nicked one rib), but it slide through her so slick, she jumped once at the sound of the shot, then simply walked off until she teetered and fell over. She didn't know she was mortally wounded - pretty amazing. The "tanto" tip he puts on them is pretty strong as well.
Oops, my bad. Posted this on the wrong thread....geesh, new year's not starting off very well!
I'm glad you cleared that up Steve, because I was totally confused! Nice form.
GregD, does STOS make another broadhead for African game which is wider?
Ken,
I know the 1 3/16th heads have taken buff in Africa but the shooter did think a wider head would have been better.
CJ
Might have to learn how to sharpen a single bevel. I like the current design and it has served me well. Easy to keep sharp and tough.
SOS, The problem with the "sharper" argument is that if one grinds a singel bevel at twenty five degrees or does double bevels at 12.5 degrees you wind up with precisely the same thing.

In theory agreed, but you'll have to grind the ferrule away for it.
Treeman, you end up with the same degree of bevel, but not the same thing. Probably be equal in terms of potential sharpness, but they will cause different things to happen. Whether one is better than the other is beyond me.

What is that website? Why only left bevel?
I have shot Zwicky's for 30+ yrs. Is it possible to make a single bevel from a zwicky? I need a left bevel. Anyone have any experience doing this?
What does the teflon do?
It makes them non-stick just in case you need to cook some fried eggs on them! LOL JK
Really its supposed to give you better penatration because of the slicker surface I believe.
I was thinking along those lines the penetration not the eggs. Sounds trival can it make that much difference.
According to DR Ashby,when comparing the same broadhead, one with teflon one without, the one with gets 12% more penetration in soft tissue, no gain on bone
Grizzlies are right bevel, to get arrow rotation while it's traveling in an animal, it needs to be right helical fletch.
Most guys use left helical, STOS is apparently going to cater to that need.
Sorry for the delay in posting. Have been gone for a few days.
Good huntin'!
Todd
Thanks for the reply Todd,,, Will they be out by the spring??? Thanks again,,Frank,,, By the way ,, put me down for 2 dozen
I'm already shooting the 160 stos nice head I see no reason not to give the SB a try wouldn't mind a few more grs either
Yes, we are working on a heavier, single left bevel teflon coated STOS. It won't yet be available this spring, but soon. I will keep you posted on the progress.
Todd
Sold Todd, thems the heads I'll shoot.
Bustin bone on whitail isn't that big a concern for me but while reading the Doc's research articles on SB, I liked the ~ shaped holes and tissue damage that the single bevel, rotating in flesh, creates in repeated testing.
I won't change feathers...too big an investment, from left to right, bt would jump on some 160 STOS left SB, teflon or not.
Will the new STOS SB come with the edge ground on it already?
I have to ask again. Why only left bevel? I use RW and really don't want to change. Guess I'll have to.
I hope they keep the standard bevel as an option for us that love the head the way it is....then add a bleeder :readit:
Won't a file turn any broadhead into a single bevel?
SL
QuoteI hope they keep the standard bevel as an option for us that love the head the way it is....then add a bleeder
I'd love a removable bleeder!! Preferably a choice of a smaller one and one the same width as the main blade.
:thumbsup:
Make it that way and watch the Woodsman's popularity drop.
:D
Charlie and JC,
I have to agree about adding a bleeder. A 4-blade STOS would be a heck of a wicked head.
I made my STOS into single left bevels with tanto tip and have had great results.
Yes, JimmyC, the edge will be to current STOS standards. roknjs, our current plans are left bevel. That decision was made since there already is an awesome single right bevel head currently available, the Grizzly.
Todd
Hmmmmm, let's see....Charlie Lamb throws out an idea for improving a broadhead. Now, din't he create some little head called a Magnus blunt that's sold a gazillion units? You'd think some enterprising businessman might consider the possibilities.... :rolleyes:
