SPYDERCO MANIX2 S110V - rope test & Epic Fail !

So how many sharpenings did it take to remove the edge? Did you use Gunmike1's method of blunting straight into the stone, or just use and sharpen a couple of times?

I use my own method of raising a nice bur (Read LARGE) then flipping the blade and doing the same on the other side..

That removes enough steel from what I have seen.
 
but agree, that it should not be on the knife from Spy...
reputable firm,but not chinese no-name...

Well, production makers use power tools to sharpen with because it wouldn't be very efficient to sharpen all the knives by hand without power equipment.

Just the process of production manufacturing....

For most people it's fine, but for those of us who test knives like we do we have to remove enough steel to get the max performance out of them.

That's the difference....
 
As a knife tester I believe that it's my responsibility to make sure all the knives I test perform at their highest level possible across the board so that I can provide accurate information.

So I give every knife I test an equal shot.

People come to me for information so I make sure that I can give them accurate information based on my testing.
 
This thread title should read epic redemption.

Ankerson,
Get ready for all the "please sharpen my knife" emails after this thread.
 
Hi everyone ! I continue...
briefly about the work done -
another knife manix2 s110v I was sent to Slovakia to Pavol Sandor for test.
first test - sharpening T7 "V" edge 30° blade 0,85mm - result - 2400 cuts -

second test - T7 "V" edge 30° blade 1,05mm - result - 2200 cuts

metal removal during grinding in the second video,to a reduction of the cutting properties of the knife.
and in both cases is very low results compared to other knives with a simple steel -

I'm not sure that i understand all of that chart, though i note a preference for 6000-grit on the automated Tormek T7 system ... why such high grit for this type of cutting?

The micrographs in the videos are excellent for gauging edge condition, though I wish we could see closer. One neat thing about them is seeing the change in edge height via the chips: The depth of one narrow chip in the first video declines from 36um at 1000 cuts to 28um at 2000 to 27um at 2400. For another narrow chip, it is 35um at 1000, 22um at 2000, 20um at 2400. The edge above the valley of the chip is wearing down.
Then again, the measurements of edge thickness presented increase to 5um after 1000 cuts (from whatever it was at start) to 7.5um after 2000, to 10um (and unable to cut paper) after 2400. For an edge sharpened at 15-dps (30 inclusive), an increase in edge thickness from 5um to 7.5um requires a loss of 4.67um edge-height, and from 7.5um to 10 requires the same. *shrug*
