I thought I would post some pictures of my south fork I re-ground recently. I started with a 36 grit belt moving up to a 50 for a rough but consistent scratch pattern. S90v @60 HRC is not easy to get a decent finish on or to remove material but my ceramic belts make a huge difference. I ground this blade down to 0.006 inches behind the edge and it glides through cardboard with minimal effort. The edge retention is extremely good with this type of steel and edge geometry.

Wow, I'll bet that thing is scary sharp (from here on out they shall call me "captain obvious"!)
 
Looks like you did nice work. The design of the knife was meant to be a slicer, so your regrind is consistent with the philosophy of the designer. If I remember correctly, Phil Wilson's custom South Forks have a thinner blade, too.

I reprofiled my Spyderco South Fork to 30 degrees (15dps). The edge bevel is fairly wide -- about 2 mm. Even at that, the edge shoulders are 0.035 inches, so your knife must cut like a laser.

So you ground your blade down to something approaching a full flat grind, almost to the apex? What thickness is the new spine? The original is 0.1185 inches.
 
Looking good man. Happy with mine stock but I am interested in getting a custom SouthFork from Phil for the thinner blade and different steel, perhaps the S110v. I never thought about having my Spyderco SF reground though... Probably because I don't have the means to do it myself.

The spine thickness is still factory thickness with a little more distal taper towards the tip. I have a phil Wilson trailing point in bohler k294 @ 64 HRC and it has similar thickness behind the edge but a little more distal taper then this one.

I really like Phil's work. S110v is an amazing stainless steel.
 
Looks awesome! That takes that knife into slicer territory much more than the standard all-purpose role; that's a good thing.

Yes, that would be a little to risky for a production company with a warranty to do.
 
The cutting edge is about a half of the height of the factory bevel. Its is more of a micro bevel and it was finished with a 3000 grit stone on a sharp maker.
 
If I could find a local dealer with a southfork I could handle before the purchase I think I would buy it on the spot. I am reluctant to get one due to the handle size. Arthritic hands suck and by the time I have someone rehandle it I could have had a custom made with similar dimensions and steel. Regrind looks great. If anyone knows of a dealer with one in stock in Austin, TX, Tampa FL or Fayetteville NC, let me know.

I find the handle has plenty of room length wise, but slim towards the front. It works well in the pinch grip and choked up.
 
I was at the SOFIC show this week and they did not one in the display. Still great selection at the show and the bushcrafter still is the most comfortable handle in the line up.
