Hey guys, I found a great deal on this file after I payed 39.52
It's a Nicholson Superior milled curved tooth file, 12" flexible standard #20138 it has holes in both ends so you can attache it to a piece of wood keeping the file stationary and moving the Grizzly down the length of it maintaining a constant angle.

I bought a few extra so if you want one I can get it to you for 25.00 delivered, just PM me.
I call this file the Grizzly tamer.

I put a piece of wood at the end so it catches on the edge of my bench, you can really take off some metal quick setting your new bevel easily.
