Finished up the performance testing this morning. This was my full battery of testing, that's 3 stages, rope, cardboard and wood. The edge was reprofiled to 30 degrees inclusive (15 degrees per side) and finished with the 400 grit Congress Silicon Carbide stone.
OAL - 9.5"
Blade length - 4 7/8"
Handle - 4 3/4"
Blade thickness - .120"
Thickness behind the edge - .020.
Weight - 5.4 oz
Blade Steel - CPM S90V
Handle Material - G10
1st up was the 5/8" Manila Rope, made 500 slicing cuts through the Manila rope and it would still slice printer paper clean and the edge still had good bite. Manila rope is very hard on edges and abrasive, but the edge held up very well.
2nd was the Cardboard, the knife was sharpened before this stage after the rope to clean up the edge from the rope cutting. It would still cut printer paper easy and clean after this stage. As you can see I cut a lot of cardboard here.
3rd stage was wood cutting, I made thick and thin cuts out of the wood to check the edge, it held up great with no chipping or rolling. The knife wasn't sharpened before this stage, went directly from the cardboard to the wood.
The Spyderco South Fork performed extremely well throughout the testing process, was very comfortable in hand with no hot spots that I noticed in use even under hard cutting. Edge retention was fantastic as Spyderco got the HT of the CPM S90V spot on here so it really performed big time.
Sal, Eric and Phil Wilson should be very happy with this model.
