I am looking for something to remove a lot of metal quickly. The 80 grit silicon carbide sandpaper works excellent for a minute or two then the cutting edge is dulled. Not working with super steels but I am sanding about 1/2" wide , about 4 inches long so I am not grinding the edge. I am thinning some blades , or re profiling. I just spent about 2-3 hours sanding down the 4" blade. I am also using Norton oil stones , crystolon and idia and they are excellent stones for working on the edge but slow down when cutting a wider area of steel.
 
I have used my Ace hardware SiC stone for that purpose. A 80 grit for the coarse side and 180 grit on the fine side. It cuts fast. They are a black stone, the PLU ends with 1165. This was a short supplied stone and are hard to find now. They sold for 13$. A 2x8" stone. DM

Norton combo stone in 2 sizes can be found in home hardware,and also their garden stone...they all do amazing job on 99 perc of steels,i sharpened s30v without any problems with ease.
 
Sounds like a belt sander is the right tool for this job. A 1x42 or similar would make this a lot faster for you. Did a pretty nice job smoothing and thinning my 240mm Gyuto with my Kalamazoo 1SM. I should really put those videos on youtube at some point...

2nd the belt grinder. You can get metal cutting belts for a hand belt grinder and lock it in a vise. All the hand powered options for removing a lot of metal are varying shades of frustration and pain. They WILL work, just not well.

If manual is the only option:
Baryonyx manticore
Coarse side of the Zandstra/Foss Speedskate stone, used with water
 
Oh yes, I missed the thinning part.

I recently did that on an 8" chef's and it was a lot of work. Not terrible if you're just thinning the edge some but the overall geometry is quite a bit of effort.
 
Before I found out about the Baryonyx Manticore, and after a lot of research, I bought a 120 grit diamond plate, then 80 grit, thinking this is the quickest way to hog off metal freehand, but for me it wasn't. Usually the instructions for diamond say to use light pressure, but (with some good advice from forum members) I found I could remove metal faster with SiC because I could use more pressure.

I haven't found anything that works as well for this as the 60 grit Manticore and use it for the majority of my sharpening, as well as reprofiling. I enjoy sharpening but don't want to spend anymore time at it than I have to.
 
Plus 1 for the manticore. I was not to impressed by the looks of it to be honest but once I put a blade on it that changed my mind. I had a stainless kershaw with a chipped tip. Knowing that , you can say I was digging into the stone. I thought I was wearing the stone but it was actually metal dust and it was very quick work. This deal was not a dud. Thanks for the recommendation...
