Just wondering if anyone made a 4 blade woodsman type head.
Might just be too hard to sharpen.....?
Thanks
I always thought about this also. 4 blades 90 degree angle.
Figure the bevel angle would be kinda blunt. The woodsman has a 60 degree internal angle and a fourblade would have a 90 degree internal angle.
I was thinking that too.
I'd think there would be enough room to sharpen with a file.
If there wasn't one of hose dual carbide " V " scraper sharpeners should do ok maybe?
almost impossible to sharpen, which is why bleeder blades were invented for twin blades.
Was a pretty nice 4-blade head made in the 70s called the Black Copperhead. If I remember correctly, only one side of each blade was sharpened. Sort of a single bevel. Would sharpen by running a file down two edges, then turn the head 180 degrees and do the same to the other two edges. Could use a stone instead of a file, of course. Good head. Wish I still had a few. They do turn up on the auction site every now and then.
I've got two designed, but I don't think it would be worth the money to get them to market. One is designed as Orion mentioned. Single bevel with opposing bevels. Would get the angle down to 45 degrees, but would not have any rotational benefits as they would be cancel each other out. The other could be sharpened with a file, or a V type sharpener. That design would have a pyramid tip that would have to be sharpened seperately and would behave more like the trocar tips on a Muzzy. Would love to find one of those Black Copperheads.
I was thinking about this a while back. I was looking at a vpa when I was thinking about it and now that stan spoke up I think red feather would be the people to market the concept. A single bevel, machined, 4 blade. I think something closer to 1-3/16" or 1-1/4 would be sweet. A 45 degree single bevel would be better then the standard 3 blade double bevel @ 60 degrees and with the quality of steel they use it could be pretty wicked.
I don't know if it would actually provide an advantage over a three blade but it's a cool alternative.
while 4 blades are arguably better than 3 blades, no matter what the angles each blade is set at i think the sharpening issue will still be the concern. dunno how it could be done double bevel, and with the blades so close i'd wonder if there was an advantage to single bevel - or even if it would work ... ? just dunno ...
What about a two blade with exagerated 1" bleeders that go out past the fixed two blades.Just a thought
I think a 4 blade could easily be sharpened. It would require something similar to a snuffer tamer.
One of the better "large" bleeder blades which attach to a broadhead is the 4 blade Muzzy Phantom.
StanM: I have a few of the old Copperheads. I could send you one.
