Hi Mark et Al.

unfortunately the setup is put away so I can’t take a cell phone shot. And yea… the pix are too close up to make sense of this without my secret decoder ring interpreting  my writing;  as I wrote:

2. These show the same moment in time but the rest of the blade (will not fit, even on low power, into a single photo. One is of the b…[Read more]

LOL,

Yes I’m getting a bit OCD, and yes my career is involves nanometer level precision. I get this is a knife sharpener and on a hobby budget. But I’m going crazy chasing that apex / flat shenogi on this blade!

My take away is to suck it up and micro-adjust on every sharpening medium (as long as it matters – aka in the case of a large…[Read more]

Very Interesting observations:

I discovered with the help of a sharpie that I needed to sharpen now at 13.8 deg to best hit the full 50/80 grit scratch pattern shenogi s that’s what I did.

After re-calibrating and chasing the Apex using the 100/200 grit stone, I started getting a better shinogi, but had a devil of a time chasing the apex for…[Read more]

To Shapton glass or not at this early stage of my journey. That is the question. <i>Whether ’tis nobler in the mind to suffer The slings and arrows of outrageous outlay, Or to take arms against a sea of  perhaps troublesome steels, And, by trying the Glass, have another tool to try.</i>

Lol, ok, I’m leaning towards using my diamonds on sub 61 is…[Read more]

<!–more–>Marc,

No disrespect taken… again…..

and your have no idea how many prior threads I’ve read or reread and bookmarked or copied bits out of and consolidated into a “Notability” note ( like Evernote).

I’m humbled by your wisdom and acute recognition of the rabbit hole of wanting better/ easier.. just because… You are spot on in th…[Read more]

Good stuff here and I’m replying to simply resurrect  this thread to see if anyone has any updates.

Edge-leading, trailing, and -parallel strokes.. hmmmm good stuff.
my $20 scope and my $50 is Celeste on vs 500-100 Dyno lite . hmmmm…. Makes me ponder the next scope… for science sake… I’d love to have a wireless scope with good DOF and magnificat…[Read more]

Mark,

Thanks.

The Jende vid is good. It’s consistent with all other all good vids on lapping whetstones.

and yes, you’re right about keeping the whetstones flat. Always. I follow your frequent process on my larger stones pretty religiously and that am for the tip/reminder  to do the same in the WE.

Nice hint on 1- use the longer rods. – chec…[Read more]

Yes I get the all stones and diamonds scratch! It’s the level f scratches that county, and your fingernail test is semi- akin to a “cut a pice of paper – phone book or copier – and if it cuts smooth, Irish hi good enough.

yes Mark seems to have Japanese knife experience and I’ve learned a lot from reading his posts and blog. Looking forward to re…[Read more]

Ps. It’s kind of fun. I’ve learned  to save the usb scope pix to a Dropbox director on my Laptop and can now grab from my phone and drop in here after saving to my camera roll. The journey indeed continues !

Robert,

I think j I still like microbevels as it makes sharpening or touching-up so much easier and for me, on some knives and tools (like my Marples chisels), it provides a very nice edge at least in my humble experience. AND, as I said, it makes sharpening so much faster,

I do completely follow your concept of grinding with the lower grits to…[Read more]

I’ve got an interesting twist / update to the theme of microbevels….

Be careful what you decide to micro-bevel. It may be a permanent geometry.

So, as I progress and get more experience and confidence as well as broken in stones, I’m moving to some of my better knives while still avoiding the powdered steels… I decided to go at my Shun Yanagib…[Read more]

All,

Thanks for all the commentary in this topic which has taken a left turn down a rabbit hole of files and determining a steel actual hardness.  All the above  moments are fabulous!

My biggest takeaway is that I whole heartedly agree with Mark that we really can’t blame the steel so quickly for what’s most likely user-error or let’s rephras…[Read more]

Thanks Robert.

It’s funny you mention chasing the simple things firs. My career is precision motion control. Think robotics. I’d say that 85% of all problem we / I’ve seen over the decades is cable related! Chase the simple things first! Yes Sir!

YES to the too much pressure!

Interesting conflict you mention on edge leading vs edge training…[Read more]

As I promised, here are a few photos of the edge POST blending the microbevel on a series of strops (down to .5 micron). I did a series of about 4 progressive angle increases stopping 2 deg. above the final microbevel angle.

In this one you can see the “rough” scratches that indicate to me anyway a LACK of fully polishing with each and every…[Read more]

Robert, Tc, and Mark,

Thanks for the guidance!

I’ll be the first to admit that user error and a learning curve are likely the root cause of the observed symptoms.

I’ll give the stones more time to break in and see how it goes.

Yes Marc, I need to do a better job taking and posting consistent photos. Heck, I’m happy I was even able to get the p…[Read more]

Time to put on a micro-bevel WITH OUT diamonds. Ceramics – films- strop… hummm, will this work???

1600 ceramic – 2 deg mico-bevel .. SUCCESS!  But why are the diamonds tearing out the edge?

So  I progressed to DLF and stropping (2 deg out from the micro-bevel)

I’m generally pleased with the edge, but want to understand / learn about the e…[Read more]

3000 – shiny, but the edge still “micro-grabs” when slicing paper – photos

1200 then 1600 ceramics…

Lapped with diamond film (1.5 micron pic shown)  – still have tear-out!

Stropping (at 2 deg. less ) still didn’t help … duhhhh

To be continued ( size limitations ???)

So the formatting looked good. Photos came in where and how I expected, so here are a number of sequential photos.

The set-up ( after the final passes of micro beveling and a “happy knife”  on a messy kitchen counter.

100 grit – starting point

200 grit – not any better tear

Skipping 400 and 600 progression photos  – 800 grit is showing n…[Read more]
