yes lets hear the results

Well those are the results. 150 cuts through 1" manila rope. That is a full one inch not one lay like some test with. So the number equivalent is 3x or 450 cuts. The blade could have done more but I got tired and my hand had a blister. That was with 5160. I also did some testing with my Damascus and quit at 100 cuts. I guess I should have kept going but It gets really tiring after about 50. Edge geometry has a lot to do with it but the hardness and abrasion resistance is important too. have to get the balance. I also did about 12 practice knives before my first JS performance test and every one did the rope and 2x4 cuts multiple times before resharpening, some only did 2x some as many as 4 before I bent them. All passed. I had to do the test a second time because I took too much time to do the fit and finish. I would then drive the tip into a 4x4 and wedge it out. Only one tip snapped.

I have not really done a full test since switching to parks. I get to about 50 cuts on the rope and chop the 2x4 a couple of times and there is no damage so i move on. I guess I am going to have to do some more here shortly and see what comes of it.

OK, guys....
Lets stop this before it gets ugly.

Chad - I am not sure where you heard that CPM-154 is quenched in oil by most folks, but for knife blade thicknesses it is usually quenched in moving air or with quench plates. Most makers I know use quench plates.

The OP has said he is getting canola oil, so there isn't much point in discussing this any farther.

I am going to close the thread.
