Q) Again , how bad is it ?

Pain = The gymping on the spine hurt like a S.O.B .. Also the shape of the grip when scrapping wood ( that bushcrafty stuff ) ... Wow it hurt ! Scraping wood with the spine hurt like hell ! ( I rate this knife a Pain Giver ) Oh yeah ! Kind of makes you glad you din't pay thru the nose for a hand held torture device .
Speaking for myself , this knife will never be used again . Be a cold day at the end of the world before I touch it !

Performance .. If me m serves the edge / appex deformed / rolled and caused a failure at 500 slices . A quick wood strop restored the paper slice performance !

The spine was ground so the knife would scrape Ferro / wood . Speaking of ferro ! , one scrape was all it took to start a fire .

Edge was a reground on the whetstone grinder ( 80 grit ) . Fasctory edge was ................... very ho hum ! ( What's the point of testing an obviously poor edge )

Overall = Very tight lock up / no slop / play .... Not comfortable in my hand at all . ???? Don't know why people like it so much - do they ? Definately a knife I would leave at home going anywhere or happily trade away / sell .

What's the point of testing an obviously poor edge

I think this is a good way. In CATRA tests, rope cutting competitions and many researchers, sharpening is performed to the highest possible quality. This is good for science. This shows the maximum that steel of this shape and this heat treatment can show. Most people, when they buy a knife, end up sharpening it manually with a stone in a circular motion or back and forth along the edge. The bottom line is that a knife that is advertised as having good edge retention will retain its edge about the same amount of time as a cheaper knife, or maybe only slightly better. For example, here is my father's knife and his stone, he sharpens it in a circular motion, he is only about 6-7 years old. And an older knife, it is for preparing meat and household work, it is about 40 years old, it is occasionally sharpened with reciprocating movements on the same stone. I think sometimes have to try to test the typical sharpening that people do to understand what to expect from a knife in reality

A few years ago I tested sharpening methods .. Also tested Grit !
Conclusion was ....................... The steel want's what the steel wants ..
It is up to the user to find out what their particular knife wants if they are chasing edge retention .
The difference can be as much as 400% + or - depending on what you are doing .
That is a massive difference .

I have tried to involve other people in Edge Lore ..........

Cos ... There are those that say Hand Sharpening is best !!! Unfortunately they are unwilling to actually Prove it !
I would love to put :

Hand Sharpening against ....

Guided Sharpening / fixed angle sharpening
Whetstone grinder / knife sharpener

And if anyone is interested , Dual Grit Sharpening .. One grit on one side & another grit the other side ..
I think I stopped at 320/800 if memory serves ..
Was testing a Spyderco spy27 ... 950 on a ground edge / 1150 on a dual grit edge ( Guided 320 / 800 )

Sharpening is an interesting Game !
