Not much use for loosening the action, but I found it interesting, looping a piece of paper around the blade by folding it and using the folded corner to lift the blade, although it has problems with a sharp blade.]]> jasonstone20 TuneUp's Wed, 21 Jul 2021 16:25:30 +0000 https://oldforum.beyondt01micron.com/read.php?7,80795,80795#msg-80795 https://oldforum.beyondt01micron.com/read.php?7,80795,80795#msg-80795


I plan on restoring and sharpening it. I think I am going to leave the chip in the handles because they are plastic, and also leave the patina on the blades. Most of the work that needs to be done is on the action, it is very hard to open the blades.]]> jasonstone20 TuneUp's Sun, 25 Jul 2021 02:10:48 +0000 https://oldforum.beyondt01micron.com/read.php?7,80602,80602#msg-80602 https://oldforum.beyondt01micron.com/read.php?7,80602,80602#msg-80602

after making some leaps forward in terms of sharpening, I'm experiencing something very strange.
I mainly focused on kitchen chef knives in the last few days. I got 1 in x50crmov15 ~56HRC and 1 in Niolox 61HRC. The problem I'm having is that even after cutting 2 carrots I can already see reflecting parts on the edge.
The sharpeness after the stones allowed me to pushcut newspapaer cross-grain easily and cut curves into the newspaper. Hair was caught above skin. The finishing and deburring stone was a Spyderco Medium. The edge bevels were 15° with a 17° microbevel. Second try was 17° bevel with 19° microbevel. The problem was more or less the same.
I'm starting to think my birch cutting board is causing the problems, because even after intentionally hitting the edge of the cutting board with the Niolox knife, I could see no edge damage at all. But if I slice the knife over the cutting board 50 times with moderate pressure, the edge shows significant damage.
Any ideas? Not deburred properly? Abrasives in the cutting board? Wrong cutting technique?]]> sai TuneUp's Sun, 20 Dec 2020 12:49:43 +0000 https://oldforum.beyondt01micron.com/read.php?7,80157,80157#msg-80157 https://oldforum.beyondt01micron.com/read.php?7,80157,80157#msg-80157 [www.youtube.com]

Does something like this concern you from a standpoint of causing damage to the knife through overstessing the metal? Would the damage climb well up into the blade or just be contained at the edge?

[www.youtube.com]

I have the same stone and have used it similarly on a Svord EDC knife, works pretty well for this sort of job. But as mentioned above, I am hesitant to do anything like this again until I have a better idea of what sort of damage might come to blades doing this.]]> YESH TuneUp's Wed, 12 Aug 2020 00:52:19 +0000 https://oldforum.beyondt01micron.com/read.php?7,79792,79792#msg-79792 https://oldforum.beyondt01micron.com/read.php?7,79792,79792#msg-79792
Do they work well in this regard to minimize the burr? I was also considering the Naniwa Superstone line with a similar combo of 220 or 400 & 1000, which are known to have the desired properties. Also, looking at the King Deluxe lineup with the 220 & 800 or 1000 or 1200 stones.

I only have knife in the Class 1 steels form Svord L6 in the mid 50's RC up to INFI/AEBL/52100 high 50's RC, a couple Japanese White Carbon steel up to 63 RC. Just one more which is 1095 at 67 RC.]]> YESH TuneUp's Sun, 26 Jul 2020 17:40:07 +0000 https://oldforum.beyondt01micron.com/read.php?7,79762,79762#msg-79762 https://oldforum.beyondt01micron.com/read.php?7,79762,79762#msg-79762

The color in the marker to make sure they are hitting the edge bevel, but note this doesn't tell you if you grind to the apex, you could easily not see marker and be far enough away from the apex that you are not even sharpening the knife. The way most deal with this is to over grind intentionally to get a huge burr that they can see and or feel.

This is then repeated by regrading the wheel and grinding the entire bevel again (this serves no purpose aside from aesthetics). There is more over grinding to a significant burr. Then a 4000 grit waterstone is used which is regraded with a 1000 grit stone (?) and then the knife is hit with no angle control on powered strop with compound which ends up being a mix of compound + steel. If that leather was a stone everyone would know you would want to clean it for best results, but for some reason people think strops will work ok if clogged with steel.

In the end the knife is :

-faceted, you can see multiple uneven grinds
-it barely scrape shaves arm hair

Now can the Tormek get better results - of course, but this video and so many others so clearly show that $1000 worth of equipment with little understanding of what is happening achieves little. But in general almost all of the Tormek videos have the same issue :

-they always over grind to huge burrs
-there is micro-beveling
-there is no check for the ability to slice, they just push cut]]> CliffStamp TuneUp's Sun, 26 Jul 2020 12:10:08 +0000 https://oldforum.beyondt01micron.com/read.php?7,79672,79672#msg-79672 https://oldforum.beyondt01micron.com/read.php?7,79672,79672#msg-79672
This will be useful once I figure out how to use it. I thinned out a $0.99 paring knife. I also sharpened it, and got it sharper than I had been able to get this knife, as these are usually difficult to sharpen past shaving sharp. I got this one tree-topping. I didn't use the stone ehen it had the finer grade set on it, I only used the coarse. It ground pretty fast. The knife turned out ugly, but it cuts way better. I just need to practice. I sharpened my PM2, and got ok results. There are just a lot of adjustments and angles on this machine that can be used.

but decided that it deserves its own:


"For the past couple of years I dipped my toes into the oil stones (both man made and natural) pond and some european made Al2O3 and SiC puddle.

I am embarking on a journey true japanese water stones and knives.

After recent work with SPS 1200 and 6000 and single bevel deba knife in shirogami I decided to purchase a deba knife but the only stone I have is 1200 branded Makita (most likely produced by Matsunaga - King).

After many frustrating hours of youtube and forums I can see three paths in front of me.

1. Chasing the "kasumi" finish with man made stones (JNS are crazy expensive) - the high contrast between the soft cladding and the hard core. From what I have seen until know - KING 800, KING HYPER 1000 (standart - hard, not the soft one), Suehiro Cerax 1000 give pretty decent "kasumi" finish.
And here I make the link with this topic - Naniwa "Super stone" 400 (nowadays "Sharpening stone" line up) looks like a candidate for such "kasumi" finish.


2. Going straight for maximum sharpes and polished bevels - 300 KING, 2000 KING Hyper, 8000 King or 8000 Kitayama/Imanishi Bester"

Basically I am going to switch to japanese kitchen knives - deba, nakiri, gyuto in the next year and it's time to buy some stones.

As an amatior youtube content creator I want to explore the unknown stones (with too little or no information in Youtube) like KING 300, Imanishi Bester 400, KING Hyper 1000 (both soft and hard /standart/), KING Hyper 2000, KING 8000 gold stone and with small audience, not monetized channel and no vision for patreon support it will take me at least a couple of years because stones are not cheap and free time is diminishing luxury.

The question is what 5000-6000 grit stone keeps the "kasumi" finish - Suehiro Rika 5000, Shapton 5000 or just micro bevel and polish the back side - the "ura oshi" on 6000-8000 King or 8000 Kitayama/Imanishi Bester or even on a Translucent Arkansas (I tried it and it works).

Is esthetic more important than sharpness and is the "kasumi" finish only a forum trend and unnecessary complication to a straightforward sharpening job?

What is your set of stones and techniques for Shirogami and Aogami single bevel japanese kitchen knives?

What other unknown/ less known stones do you recollect?]]> stefan_wolf TuneUp's Tue, 14 Jul 2020 09:32:33 +0000 https://oldforum.beyondt01micron.com/read.php?7,79607,79607#msg-79607 https://oldforum.beyondt01micron.com/read.php?7,79607,79607#msg-79607 YESH TuneUp's Mon, 13 Jul 2020 09:14:34 +0000 https://oldforum.beyondt01micron.com/read.php?7,79514,79514#msg-79514 https://oldforum.beyondt01micron.com/read.php?7,79514,79514#msg-79514
The knife gets used (so far anyways) with a draw cut pushed away from the body to slice through vegetables. The highest I have taken the apex to is DMT Extra Fine or Fine. This has been used with a Diafold, but I would like to purchase a nice full size bench stone as the Diafold just is not ideal for a bigger blade.

I remember Cliff posting about problems he was having with certain higher grit DMT plates, I want to say it may have been Medium Extra Fine. Did you ever figure out what was going on or have it replaced? Did it just wear in to where it was not leaving the odd heavy grit scratching on the apex?

I was also looking at the Atoma 1200, which may be all I really need anyways. Anybody here using them currently? I also can't help but wonder if something like the Atoma 600 or DMT Fine may be better as it's more of a slice.

I am not doing ANY chopping type cutting with it, mainly just the weight of the knife when I draw it forward causes it to just fall almost effortlessly through the veggies. Thanks in advance!

A few points about this video (only dealing with that one question)

-he completely mischaracterizes Carters position

Carter sharpens the way he does because he only cares for performance not aesthetics, hence :

-it shows the clear difference between a hobby sharpener and a professional sharpener (Carter)

-he is completely off on one radial point, edge thickness

In regards to the latter, he notes reducing the edge thickness will lower edge retention, that isn't the case in general, and would only be the case if you thinned the blade to the point the primary grind collapsed in cutting, but that isn't the edge going dull, it is the blade suffering gross failure and to do that by stones, well it is beyond the ability of almost anyone in hand sharpening.

He also makes odd comments like he knows professional chefs who have used a knife for 30 years and never had it thinned. Well if you have never had to sharpen a knife in 30 years enough to thicken the edge, it just means you didn't use it a lot or you are willing to use it dull.]]> CliffStamp TuneUp's Sat, 18 Jul 2020 19:25:27 +0000 https://oldforum.beyondt01micron.com/read.php?7,79359,79359#msg-79359 https://oldforum.beyondt01micron.com/read.php?7,79359,79359#msg-79359
PS. I tried stropping, and that helped the edge somewhat, but it only got the blade to scrap shave, and it still cut into my skin.]]> jasonstone20 TuneUp's Wed, 08 Jul 2020 09:55:02 +0000 https://oldforum.beyondt01micron.com/read.php?7,79298,79298#msg-79298 https://oldforum.beyondt01micron.com/read.php?7,79298,79298#msg-79298
Something I’ve noticed happening to me, typically always when cutting phone book paper against the grain, is I get U-shaped cuts out of the paper. Example image:



I’m doing slicing cuts across the grain testing sharpness off the stones (haven’t graduated to push cuts against the grain just yet :D). The same knife cuts cleanly vertically with the grain and at 45 degrees to the grain, typically only run into this cross-grain.

What I *think* is happening is that the heel of the knife is not as sharp, so it’s folding the paper edge over. Then as I slide along it’s hitting the sharpest part of the edge which slices through the folded edge easily and leaves that distinctive shape. I noticed tonight on the blade where this is happening that it had a particularly sharp section towards the forward 1/3 or so of the edge towards the tip. That area could push cut phone book paper for example.

Does that make sense, and did I diagnose the cause correctly? And if so anyone have any tips that helped them for getting more even sharpness along the edge especially towards the heel?]]> jloden TuneUp's Tue, 30 Jun 2020 18:31:52 +0000 https://oldforum.beyondt01micron.com/read.php?7,79228,79228#msg-79228 https://oldforum.beyondt01micron.com/read.php?7,79228,79228#msg-79228 jasonstone20 TuneUp's Fri, 26 Jun 2020 20:01:34 +0000 https://oldforum.beyondt01micron.com/read.php?7,79155,79155#msg-79155 https://oldforum.beyondt01micron.com/read.php?7,79155,79155#msg-79155 [www.youtube.com]

I own a copy of The Razor Edge Book of Sharpening - in fact it's the first book I ever remember seeing on sharpening ~20 years ago. Now that I'm getting deep into sharpening and experimenting with various abrasives & techniques I'm very curious about these. To be honest I didn't realize until this morning they were still even sold. I just sort of assumed they had sort of disappeared like many other mail order businesses in the late 90s.

Might pick up a set just to experiment, but thought I'd ask on the forum here if anyone owns these or has tried them and has any feedback. It's interesting to me they have next to no information on them (abrasive type, binder... heck, the website doesn't even list the full dimensions of each hone).

It's several years old but this was the video that prompted me to look for them today and see if they were still sold:
