Hand sanding is your friend. Do not rush any prosses it is easier to take material away, putting it back on is a hole other subject lol
Take your time and pay attention to detail.
Remember drill all holes before heat treating it sounds stupid but i was so eiger to finish my first three knives that i kept forgetting to drill any handle holes before heat treating and finally decided to take the time to write out the knife making prosses and check off each step as i went. It is an easy thing to forget because alot of ppl think that the handle is the last thing that you do but in all reality it is one of the first things.
Grind shape of blade out
Clean blade shape up
Cut handle blocks out fit to handle so that there is enough material on all sides of the handle to work with.
