Thanks for sharing that. One of the best videos I've seen!
That's a good theory KT. Take a piece of hide and poke a 2 blade and a 4 blade hole through it. Then slide a finger in the hole to see which one is looser. Much less resistance with the 4 blade.I think a 4 blade cut would help keep it from plug'n up sometimes. Just a theory in my own noggin though. LOL
You have to look at total cutting surface. A 2 blade 2" cut is 2". A four blade 1 1/4" is 2 1/2 inches total. A three blade 1 1/4" is about 2" The four blade has more cutting surface that the 2 blade and the 3 blade has about the same cutting surface overall even if the 2 blade is 2".That's a good theory KT. Take a piece of hide and poke a 2 blade and a 4 blade hole through it. Then slide a finger in the hole to see which one is looser. Much less resistance with the 4 blade.
