A couple Of questions regarding edges.

1)How often should you do your edges with a file Guide ?(base and side)

2)Should I just buy a Diamond stone/Gummy stone and just get out any Burrs/nicks
Every time I wax my board ?(Do I need both or is one better than the other)
Should I get a Fine/course diamond stone?

3)I wax my own board now, so was wondering if it’s worth getting my own File Guides/stones Ect..
I don’t mind taking the board in if it’s only 2/3 times a season to get the edges done,

This leads to my next Question,

4)All the Faq’s and vids, I have watched they put a few layers of tape on the file to do the base and use a guide for the side edge ?
I was thinking about getting a base file guide 1” but seems a lot of people use the “few layers of tape” way
What’s everybody’s thoughts on this ?
