Some interesting results from cutting rope ...
From the results , you can see that sometimes a nice fresh regrind really helps
And using a guided knife sharpener on a FUBAR factory edge , may not help !

I have a few knives out of my JUNK knife box , I might regrind them and see what happens ..
Especially as some ( many ) knives came BG ( Before the wet stone Grinder ) Many / many / knives came BG .

So lets talk D2 ...
I like D2 , D2 is relatively well known and reasonably abundant as a material .
D2 when properly done is really good stuff . ( Im a machinist from way past )
Anyways ...

Factory Grinds ...
As I am finding out , a very large percentage of knives have poor factory grinds ( I'm being generous ) .
And the issue with say guided knife sharpeners is that they follow the factory grind . So it can take a long time ( if ever ) to correct a poor grind !
The wet stone grinder is different as the knife is sort of jigged into a fixed distance ..
So rather than following the factory grind , you are making a new / straight / even grind .
And this new even grind , some times gives rather dramatic improvements to a knives performance . 😁 😁
Obviously , it's not the best edge in the world , but it's straight and even .
As well , there is maybe a 50% or more performance increase ...
Whilst a guided knife sharpener may actually lose you performance ( such is life ) .

Anyway ... Lets get back to D2 ..

As can be seen , decent D2 returns around 450 on the rope ..

QSP Parrot D2 - 450 with a guided edge
CH 3530 D2 - 450 with a guided edge ( not on the list )
TwoSun TS-89 D2 - 450 Factory Edge ( ? What the parking lot - Right ! )
Ganzo FH-51 - 450 with a guided edge
TwoSun TS-16 D2 - 650 with a reground edge
TassieTiger D2 - 450 with a guided edge ( not on the list )

And a whole bunch off alleged D2 that simply did not make the cut . ( Many not on the list )
My Ganzo FH-41 was over cooked and the cutting edge had stress fractures and failed at 350 cos the fractures were tearing the paper . I was not going to remove years of use just because of some stress fractures that would have little effect in real world use . Though they did effect the test though ..
Anyways , decent D2 should be playing in the 400 ball park .. And really good D2 , well , I got 650 with one knife . ( Obviously the exception to the rule ) I really wonder if maybe they some how put the wrong steel on that knife , accidently put premium steel on it rather than D2 ?
I have alleged D2 that fails at 50 slices and on up .
Civivi Dogma D2 ... This knife has been at the rope 5 times from memory .. And the last time I put it to the rope , it had been reground 3 times at least and did a 150 slice fail . ( Really Poor performance for D2 )
So , ..................... Some knives are just dogs !
What's the point ?
I want the best edge I can do on a knife ( That's just me ) , and in regards to performance ... That's just a black hole of misinformation that will never go away until every person on planet earth does retention testing .
Yeah , it will stay a black hole ...

A) Performance is directly related to how good or bad the factory bevel / edge was / is to begin with .
B) Depending on the re sharpening method employed , you might improve performance or not .
C) For most people , it's not really important or optimal to invest money on knife sharpening equipment like a wet stone grinder .
D) But if you do knife reviews ? Which is more important ? Facts / data or opinion ? ( So much opinion out there not backed up by facts / data )

Hopefully this information is informative ...
And as for me - I do what I do simply Cos I need to know ( In other words , cut thru the BS or opinion or what ever )

Hmmmm , and it's only a partial list ..
I did not record the earlier tests .. So while a lot of knives were tested , I only remember a few results .
Unless they are on video and posted on Utube .

I currently have 7 knives in front of me out of my Junk Box that have been reground ..
Most being Before Grinder ( Wet stone grinder ) And all the edges were rubbish to some extent .
A varied bunch of knives and steels ... Some previous results I remember and some I don't , but they all ended up in the junk box .

old4570, Are you referring to primary grind when you write "factory grind" above, or secondary grind?
I do not understand HOW your "wet stone" powered "grinder" produces more even "new" straight grinds then generally any guided sharpener? The apex is the edge, and when reprofiling with my KME, clamped (no table option yet), reveals an uneven primary grind, that my eye misses, by sharpening the knife's secondary bevel meeting at apex. Warpage, uneven primary grinds, pivots off, etc., will look like uneven secondary bevels hilt to tip. Even though the KME holds inside 1 degree hilt to tip all the time.
For the grandkids inexpensive knives are the rule, so your results are focusing my efforts on training them sharpening skills. Enjoying your work's trends and patterns, thank you.
 
Wet stone grinder ... It's a jigged system ..
And depending on the width of the wheel , grinds a more straight even edge ..

Problems ) The problem with some blades ..
1) offset edge or bevel - very common .. ( Not in the middle for ? variety of reasons )
2) dips or valleys in the edge / bevel - These occure because the operator lingered in one spot too long .

Ordinarily these things are hard to spot .. And a un even grind , wears un evenly .
I been meaning to show this .....
Any way , the wet stone grinder shows these up right away ..
So the edge is layed bare for all it's perfection or faults ..

Factory grind = Factory edge - Edge the knife came with - edge untouched by me ! ( out of the box edge )

When I reprofile a new knife with a factory edge, I create a new edge with the KME, good and straight, and in no way relying on factory edge. I do not think I have an "issue" other then mis-shaped, warped or cut incorrectly, primary grinds and canted or miss drilled pivots. With inexpensive knives these manufacturing errors are not a problem, just use it. None of the knives I've gifted or owned, over 50 or 60 bucks, used and new, have bad enough primary grind problems impacting factory edges. If the factory edge is wonky just reprofile it.

Going to tell the grand kids to look at this list and watch your tubes, as you are testing the types of knives they get. Your tests have made me stay with KME's 300 grit diamond stone, using a light hand, for now, on my very thin 940's Magnacut 61HRC reblade.

Benchmade's new "Select Edge" hardware and process has got me excited enough to save up for a "Tagged Out" so I can check their "Select Edge" out on their CPM154.
 
I have a new knife in front of me , so I might have to photograph the edge as it is re sharpened / re profiled .. To show what is going on .

Review soon !

by using a 60 grit stone, aren't you essentially giving those knives a micro-serrated edge, which is good for cutting rope?
do knives with the 60 grit edge cut phone book paper with a push cut?

THe 60 grit is already grabbing printer paper .. If you strop it to remove the high spots , it can push thru printer paper ..
Phone book , heck , I don't even know if I have a phone book any more ?
I would hazard a guess at no !
I found a ALDI catalogue , and the answer would be no for pushing thru , slices fine , but no push .
Even my brand new Mora 2000 has problems pushing thru the paper ..
I have two very sharp Hultafors ( Scandi - fied ) that push thru .. And my Kizer pushed thru ..
Why I call these edges hacksaw blades ..
For things like wood / rope / cardboard / meat ( game ) , it makes for a nice working edge .
 
docflash, my one knife experiment prompted by old4570's work demonstrated for me what your saying is correct. I just went after a 940's new Magnacut reblade for the second time with KME's 300 grit diamond using a gentle hand, stropped trailing edge on corner of soft plastic table, inspected with 10x illuminated loup. The 940's edge push cuts gas station receipts and standard 20 pound printer paper in my non-humid environment, on its own weight, but slicing revels "micro" serrations that catch on receipt edge. At 20 n 30x it is obvious apex / edge is rough.
Blade came unsharpened on request, and I am removing minimal material as knife is heirloom grail build, so power sharpening burn is irrelevant. old4570 blades are very inexpensive and no doubt getting over heated at factory. old4570's water cooled hardware is removing burned edge. This and counting rope cuts is two reasons I can identify for increase in counts, with various exceptions popping up like the HRC estimate of the 700 cut count ganzo.
Solving these issues at the factory would require less margins or more subsidies on 15 to 30 dollar knives...
