I've heard that you can "chisel" or square off the tips on these so they don't bend or roll over.   Anyone done this?   Two of my six have done this.      Any detailed instructions would be appreciated.

I'll tell ya one thing, send the bent ones back to Magnus and they will replace them for free!

While I've not had any problems with Magnus heads, you can do a real quick and easy snip with a pair of side-cutters, and just take one or two millimetres off.

File and sqaure them off- very easy (takes 1 min.) OR tanto tip- similar to square off.  Should be able to find the tanto on a search here in Tradgang.

As you can see, this is what happens when a Magnus meets thick bone. This Magnus I had already been "tantoed" but not enough aparently.

You need to snip off, or tanto the tip, all the way to the black paint on the tip to avoid curling.

thats not a bent magnus!

this is a bent magnus



and so is this



and that was with a chisel tip 3mm wide. i don't use them any more. you can see on the 1st one, even the ferrule started to bend.

Isn't that odd? I've had nothing but happiness with my Magnus II 125 grain broadheads.

Ozy Clint,

Just curious. What broadhead are you now using?

All cut on contact broadheads should have a tanto tip applied with a file.

If they are filed to a needle point, there is not enough strength in the tip to resist bending, once the tip starts to curl the rest of it follows.

It doesnt matter how well the blade steel is tempered, its the needle point that causes them to fail.

Ill second that. They are fantastic people to deal with, and will do anything within their pwer to make the customers happy.

night wing- i now use blackstumps again. i only bought some magnus because the blackstumps were unavailable for a couple of months and i needed some b/heads.

outbackbowhunter- i agree. longbowkids situation could be described as a tip curl. however my b/heads have been bent further down than the tip. not so much tip deformation but bending of the b/head themselves. strange.

i tanto the tips on all my braodheads never worry about that happening

I hear ya on the 'send them back'...but what I really want is a head that I don't have to worry about sending back when it leaves my bow.

I've been using needle points on my Zwickeys for two and a half decades, and I've only really bent one that I modified and removed too much metal right behind the tri-lam.   I have minutely tippy tip curled a few on TX rocks, and I just filed them down to a tanto and back in buiz they went.  I did chip one about an 1/8th once after passing though an animal.   My tips 'sort of' get modified in general sharpening, but they are still pretty 'needled'.

I do pyramid the tips on my Wensels to strengthen the tips.

So, if you need to modify them please do so as you need all the confidence up front that you can get....cause a warranty aint gonna draw blood.    

Is it best to file or grind when modifing?

Magnus I use a file.When grinding you have to be careful not to discolor the metal with to much heat,it will soften it.

Thanks Leland. That was a concern.

Thanks for the input guys.  I may send these back and then tanto all of them.  I like they way they fly and penetrate!

I'm with Terry on this one.

When I shot Zwickeys I never modified the tips and never once had a problem.

Over the past several years of using Ace Standards I've also never changed the tips. I've put them through elk and whitetail vertebrae (not intentionally), the offside upper leg bones of whitetails, moose ribs and a host of other nasty stuff. Not only have none of the tips rolled, they've never even dubbed.

If I think a broadhead's weak enough that I have to modify the tip, I'm probably just going to use a different head.

I am with Green on this one.
