I can't see well enough to file square.....
........at least that's the excuse I'm using today.
I file by brail more or less ,seems to work ,i just set the file in the outside corner so they sort of line up ,then rest the bottom of the file on the tie strap ,i have no idea what angles they are ,maybe a 25 top plate ,but it seems to cut pretty good ,like i said this is how i got the cutter in that pic earlier sharp ,if i can do it ,i am sure others could also if they had some tips to start with
also with square file outside in ,your file stroke should lightly be touching the tie strap holding the file like in my pictures
