Yes, I cut down an s30v blade. The facility I work in has this great policy about knives having blades shorter than 2.5 inches. I still have more cleanup work to do on the blade and actually plan on taking it down a little more before I'm finished. I used a combination of a cutoff wheel, sanding drum and files, making sure everything stayed cool to not ruin the temper. It's actually very usable at this length and still holds an edge really well.
