Sharpening To Get To Good Metal

Two Benchmade's, a S30V 940 Osborne and a 154CM 553 Tanto Griptillian, sharpened until the metal would take a high sharpness:

A lot of material had to be removed, and both knives that had been sharpened a lot were thickly ground.

How many sharpening hours approximately ?
It looks pretty extreme.. But I believe it.

With a few knives I've been really surprised how many sharpenings it took to get to good steel. Which is to say, based on results from other knives I have in similar steels using similar methods, I couldn't get them as sharp for quite a few sharpenings and then suddenly at a certain point they started falling in line with my other results.

Among those are a Sypderco I have in Super Blue, and a kitchen knife I commissioned in AEBL.

Always in search of a good choppa'

Thankfully the new Benchmade 555 Griptillian I received as a gift didn't have that problem. I think both the these knives were from then mid to late 2000's, basically when Benchmade's QC started to become not so good. Also, the S30V was a new steel at the time.

JSCT,
For the Tanto Griptillian, 16 times sharpenings over two months, and for the S30V 940 27 times over four months.

So most ppl will never get to the better material.. kinda sad.. most will probably not percept it anyway..

JSCT,
Yes, the sharpness level I was aiming for was severing a head hair in both hair grain directions, which is higher than shaving sharpness and a little higher than treetopping.
