Hi, I just bought a Kershaw folding lock blade from a guy for ten bucks. The guy wanted $20 but I told him it wasn't worth more than $10 the way the blade was scratched up.
The blade looks like somebody used a grinding stone on it, all the way up the side. :rolleyes:
I bought it for to use as a project.
How would you guys go about removing them? Thanks in advance. :)

Papersand them from rougher to finer grit and polish them after with a compound. The higher grit you'll go the shinnier your blade will be
 
Sand paper, yes, but it has to be backed up on a hard block. If you just use your fingers, the surface will become wavy.
 
I have had good luck with one of those little pink pencil erasers behind sand paper.
It seems to mold to the blade and compress a bit to leave even lines for a satin finish.
 
Thanks guys. The eraser sounds good for a sandpaper backing. This poor knife was pretty well abused by a previous owner in the respect of sharpening. Ironic as it came to me with an edge that was almost as sharp as a butter knife. :barf: I just wanted to see how well I could restore the sharpness. As I worked it I thought HMM, this was a fairly nice knife in it's day, so thought I'd ask about the correct way to polish it here.
My original intent was to just put an edge on it and use it as a loaner as I wont loan out my Benchmade edc, or either of the original Shrades I carry. ;)

Start with 1000 grit wet and dry paper, then finish with 1200 grit?

Not unless the scratches are very shallow. I'm working on polishing my Opinel as we speak and I had to go down to 800 grit just for the shallow machining marks.

Crappy pic, but this is after much elbow grease and 800 followed by 1000 then worn out 1000.

Soon I'll go to 1500 and may go as high as 2500 but I doubt it.
 
Oh btw, an eraser would probably work well. I started by using a hard block of wood but I was getting high and low spots, so I put a piece of leather between the paper and wood and it's worked very well. Just enough give, yet still firm and it gives me a large area to work on.
