Yes I would. And be deliberate about it. Draw out the shape you want then cut to your line. Then file to your profile. Don't take the directly to a thin edge or you will blunt your file. I prefer to cut the heel on a grinder, then profile with a file. But you can dull bit gradually with the file by rolling out to it. Once dulled you can hold your file perpendicular to the bit for shaping.
Thanks SP I used the grinder method you mentioned to me before on a hatchet of mine and it worked very well so I will keep with it. Just wanting to clear up about using the file: So the bit comes to an acute apex at the cutting edge, once iv'e taken the heel to the grinder it is now flat/vertical/squared off, would you then begin to reshape the cutting edge with the file at roughly a 45 degree angle straight to the corner of that square bit or do you begin with the grinder to remove the right angle edge first then continue with the file? Would this prolong the files life?
