Trev' can I offer a bit of advice? Hold fire on the file work. There comes a point in embellishing a tool at which you have to stop. Bit like those dweebs who don't who buy every accessory they see on the shelves of Halfords for their cars, from novelty air fresheners and fluffy dice to chequered flag mudflaps and 6 anti static strips hanging off the back bumper.
In this axe head I feel less is more and adding file work would ruin it. Just my tuppence worth mate.
If you're running out of things to practice on then PM your address and if I have any bits of iron in my workshop I'll send 'em to you for you to have a play on. OK? They won't be quality tools I hasten to add, just stuff I've acquired that you can use to doodle on.
That is very nice of you bud and I would like very much to take you up on that offer .as not to spoil my daily user plus I get to show off other skills on iron
