Hey, thanks.
The one I shot the hog with was as simple as you could get, just a triangle cut out and sharpened, lol. The best ones I have made, though, look a lot like Ralph's.
Along with Ron and Pappy, I use a fiber cut off disc.
And one more thing, I used ferrel-tite to glue them in at first, but epoxy holds up much better for me.
