this is the first blade ive tried to restore. got it for 4$ on ebay. I dont know its size but it is a wedge with no hollow. I pulled the scales off, they were total trash...will have to figure out how to make them eventually.
so... it didnt take me long messing around with hand sanding at 120/320/400 to realize i was doing a few things wrong... I had worked pretty quickly from 120 to 400 and noticed i still had alot of tarnishing and pitting and lines from the larger grit papers. So i started again with the 120 and worked it by hand till all the 'scratches' were going perpendicular to the blade with no lines showing going length wise. I still had some decent pitting and some dark areas so i decided to make my first sanding drum from 120 using toxic's guide. i went after dark areas on the tang, spine, and towards the end of the blade a bit more aggressively but tried to maintain even sanding along the whole thing so i didnt grind a dent into it. The 120 on a dremel leaves a very different effect then hand sanding with 120 so i worked the whole thing till it was evenly patterned. With almost all the dark areas out i moved on to 320 grit drums and worked the whole blade till i had removed the parrallel scratches i had made as vlad had indicated he does when hand sanding. repeated this with 400 and shes looking pretty good!! 400 is the highest grit paper i could find so im gonna have to order so higher grit stuff. There is still some uneven surface where the deepest pitting was on the end but i think it gives it a bit of character so i might leave it.
questions...
what speeds should i be sanding at with the dremel (been using 4 on the dremel, but i think my dremel is messed up cause i can feel it fluctuate up to something like 6 sometimes then it comes back down after a few seconds. wtf?)
can i sand the spine length wise?
do i need to follow the heavy grind patterns on the tang when sanding?
there is a very small nick in the blade, it looks like a perfect little half circle that a thick hair could fit in. When should i work this out and how?
Is it a bad idea to put a mirror finish on a wedge? Will it get scratched with honing?
All in all im really happy how its looking right now. I will try and get some pics up, tonight maybe.
thanks

Brendan,
My $0.02:
I'm thinking that the blade might have a slight hollow to it, and might not be a 'true'wedge, so a mirror polish would not be an issue. If you lay that blade flat on a hone and gave it a few passes at 4 or 8K you will see where the 'working' surface is. On a blade like that, I have a feeling it will be at the edge and spine....(those are my favorite grinds, all the stiffness and heft of the wedge, but not the work of honing a wedge!!)
Don't worry about that nick until you are done sanding, and ready to hone.
If you have a Walmart(automotive section) or auto store nearby, you can find wet/dry paper up to 2000grit. What is odd is, I have trouble finding 600 and 800 grit paper (up to 400 no problem, but between that and 1000, nuttin'). There are a few online sites that sell them pretty cheap. However, if you do not feel like waiting for the shipping, go to the woodcraft web site and see if there is a store nearby (they also sell some great wood for scales).
Something that Vlad suggested and that works well is, us a lubricant while sanding. He used 'Steroil' by dovo, I used mineroil (I think the only difference, is Dovo's is 'Sterile'+'Mineroil'='Steroil'...but that's just a hunch). This will allow the 'slurry' to work with you as you sand, save the sand paper (make it last longer) and prevents a metal powder from getting everywhere. All in all, it helps all around.
As for the blade, it looks like it has a LOT of promise. Especially since most of the pitting is away from the edge.
Post pictures of the progression if you can!
Good Luck!

some new pics... the side with the pitting is at 400 grit, the side without has had a few passes with 1000 grit. these are from my cellphones camera, but they show pretty good detail. i should have some pics from a DSLR soon.
thanks
