Looks good to me, a lot of steps are very similar to what I do. If anything, you may be working more precisely by marking the handles in more detail. For example, I start the octagon sides by using a 45* tilted table of on a little jig on a band saw and then finish them on the belt, relying on hand-eye coordination with the emphasis on them looking and feeling right over being mathematically exact. I also usually sand a bit higher if I have metal pieces in there to make sure they are nice and polished. I used to sand pretty much everything to 1200 grit ot higher, but unless you have metal or bakelite etc. in there, you won't hardly notice a difference after buffing it.
One question to clarify (and that may be in the next pictures): do you use the burning to shape the tang slot or do you actually then also burn in the tang when everything is finished. For that I would assume the slot should be narrower than the tang so that it holds on to it.
