I have not bow hunted for 20 + years, but back when I did it was MA3L's a three bladed solid welded head with no openings, nothing to get caught in brush, nothing to come off.
You could fire one through a wild plum thicket and have a reasonable chance of reaching your target. Plus have a very good chance of recovering a useable arrow on the other side. Most of the broadheads I've seen for sale today would not survive that challenge.
Also because of the way it was built, it was super easy to sharpen. They came dull from the factory, so first was a long session with a mill ******* file.
Then Arkansas stoning with oil. But there was no question about getting the angle right. There was only one angle you could get. From blade to blade.
The tame turkey I shot with one expired in less than 30 seconds. Never dropped the string on a deer, but they were the key that got me out there, watching, listening, learning.
Simple, elegant, sharp enough to shave with. Eventually the bow, quiver, arrows, camo all went to a good friend who had 3 boys who all wanted to hunt and could not afford to.
While I loved every minute of my boy hunting experiences. I vastly prefered my Rem 870 20 ga for actual harvesting. For one thing most deer activity in bow season was dawn/dusk. You stick an arrow into a deer, wait 15 min for it to lay down, and all light was gone for tracking. Seemed like a lose lose scenario.
Dawn when I would have time to track I would see deer, but always at a distance, and always spooky.
That's my experience, hope it helps someone.
