Well, I just finished my stainless steel scaled Al Mar from Ebay. The tip was blunted about an 1/8 of an inch or so. I did grind the spine being careful to keep the blade shape right. I was able to tell that if I took off too much at the blade edge, the blade would have stuck out slightly in the closed position. I guess I could have ground down the stop to ensure it closed all the way. Regardless, I am really happy of the way it turned out. I took off minimal metal, reconfigured as close to original as possible, and now I can sport an Al Mar as an EDC. I profiled it at 20 degrees on my Lansky, and man the hairs just jump off the back of my hand. I really love this Seki City steel. I had a little burr left after the white stone, so I gently stropped with Flitz, and I have nice polished edge, and great looking Al Mar lockback folder. I am one happy camper. After gently grinding the spine, I also polished it on the strop, which now looks like a factory finish. I used a grinding wheel on my drill press, and the metal never got too hot that I could not touch it. Lots of fun in the garage tonight.
