Just wondering about the logic behind and all of your opinions regarding filing an edge bevel in a fan shape, ala "An Axe to Grind."

I think it looks cool but I am not sure about the function, or whether it applies equally to all axes regardless of centerline height.

Thanks
 
I'm not gonna argue with the U.S. Forest Service - way out of my league.

I'm not always filing them back that far but I've wondered if I should be. I get the shape of the filing gauge (eyeballed) for about 3/4" back. Some worn axes I've filed the cheeks back as much as 1-1/2", maybe more.
 
You have to judge edge axe on an individual basis. Some dont need it, and some might even lose some effectiveness. Others need the transition from convex bevel to the high centerline merged a little bit so it bites easier.
 
Thanks, guys.

So it seems basically for axes with a high centerline, and just to make sure there is a smooth transition and good overall edge geometry for proper material flow.

This is much easier to wrap my head around than just always filing the edge differently in different places.

I sure pegs that you know more than the current crop of the USFS.(Most of the knowledgeable ones have retired)But MTDC is working on a updated Axe Manual.
