Sharpening.........
I have had good success with my granddad's old oil stone it's probably 80 years old and still going strong,
if I have to reshape a blade I use a belt sander with a fine belt and then to the oil stone, so far my friend
has not had a complaint about how sharp his chisels are, I guess I got it right.
I think I'll get a Craftsman set as Zulu suggests my friend has been using them for years and they have held up well.
