My Sakai Yusuke had very deep patina and it started to get very sticky with food so i decided to clean it up and take some pictures.

I'll slowly add more pictures of my other knives :)

I used 120, 320, 600, 1000 and 1200 sand paper. not very polished but good enough.

What do you guys think?

Looks good to me--fairly even haze and consistent scratch pattern that should hold up well and conceal the odd scratch from stones or food.

alot scrathes, to remove just patina i would start at much higher grit then 120.

If patina is getting rough, you may polish it somewhat with cork and stone mud (J2000 or higher) without abrading it completely as you did. Force a new patina and you will be fine.

Looks like decent work to me...better than the work I did recently. :)

Looks good, but make sure you're hitting the tip, and following the angle/curve when sharpening. I looks a bit untouched. But, nice!

The result is not bad at all, I agree. Would you want a more polished result the grids should be much closer, especially in the coarse range.

Thank you for the advice every one.

I was trying to remove some old deeper scratches while getting rid of the patina.

Next time ill try to use closer grid numbers to get more better end results.

Lefty i think i went a little higher with the angle on the tip, i have to be careful.

Hey, I like the finish. In my mind, satin is where it's at! Nice work on it. I was just afraid I saw some birdbeaking rearing its ugly head. Just wanted to make sure you were watching out for it :)

Pretty knife! I like the cutting board, too.

Lefty

I agree with Lucretia! :) Is the board Tamarrack?

finish looks fine, watch the birds beak, though.

oh my yes, that is birds beaked. if the bevel was even to the tip, i bet it would be fine.

ok ill fix it today thank you :)

Yup, but an easy fix and a great lesson learned :)

definitely. i had tips just like that for quite a while on all my knives, when i was starting out. just part of the process. i had underground heels for a long time, too. the two extremes of the knife are easiest to undergrind.

Lefty
10-21-2012, 02:04 PM
Very true! I actually fight overgrinding my heels, at times, even still. If you don't pay attention for even a second, it can happen.

You should see the job eaglerock has done, already, to fix the bird beak. It looks waaaay better.

Glad you guys pointed this out. i have to get better with sharpening :)

but now you got me scared about the heel part :O

Lefty
10-21-2012, 03:10 PM
Very close...nah, don't worry, just watch what you're doing :)

EdipisReks
10-21-2012, 06:35 PM
being cognizant of the potential problem is all you need. just check to make sure that holes aren't opening up, and if they, correct them. the tip is definitely looking a lot better!

this opened my eyes for those small mistakes i leave when sharpening, i had some undergrind with the heel too but it was very easy to fix.

one problem i keep getting when sharpening is how i measure my angle.

i don't measure my angles when i sharpen. results are what matter, not process.

I'm with Jacob on this. I just do it, making sure my mistakes aren't too bad :)

Eagle,

Are you planning on going any further than 1200 grit polish? Also did you get a before picture of the deep patina?

eaglerock
10-25-2012, 05:08 PM
I can't find finer sand paper than 1200 in Finland. i forgot to take a picture of the knife before. but it was used in a pro kitchen for 2 years without any polishing so you can imagine :)

Use worn sandpaper with some stone mud.

I wouldn't bother. It'll get scratched again anyways, right? And at some point you'll have to thin it, which'll scratch it to hell. If it was a knife with a shinogi line (a single bevel or something like a Heiji), then thinning would be much less messy, and I'd actually invest the time in keeping the knife nicely polished. Otherwise, not worth it to me.

i agree, soon it will be covered with nice looking patina so who needs any polish :D

where i can get stone mud ?

Sorry if was unclear: I meant the stuff from your waterstones.

Just start sharpening any knife, but don't rinse away the mud after and use worn sand paper or a cloth to transfer it to the blade you want to polish and have at it. That's what I'd do. Or you could generate some with a lapping block or diamond plate or nagura. We had some discussion a while ago on my 'Tips on Polishing' thread about how various grit ranges work out - stones vs sandpaper, etc - and turns out the system is impossible to figure out, or so it seems to me, so I'm not sure what 1200 grit paper relates to with stones (it might not be equal to a 1200 stone, for example). Anyway, I haven't tried polishing with stone mud, but I hear a red Aoto is good for this; I have one and the grit range seems to be in the low thousands.

Benuser

According to the grit chart P2000 (sandpaper) and J1500 have equivalent particle size, 10 micron. That's a fraction finer than a Chosera 1000. But for some reason the Chosera pattern will be more regular. I guess the stone mud gets finer with use, and the grit indicates the maximal size of fresh particles.

my king 1000/6000 hardly makes any mud, i think it will take forever to get any from it lol.

NO ChoP!
10-28-2012, 10:44 AM
Kings should get nice and muddy. The 1k side is very clay like. Salty has a vid about polishing a knife to a mirror finish....

Are you using wet/dry paper? The addition of water to the sanding process also will increase the polish....

Lefty

I like scratches on my knives, if I made them through regular use. They're like little battle scars and they make me want to use the knife as a tool, rather than display it like a showpiece.

I actually had a conversation with Adam Marr about the gyuto I have that he made for me. It's a great working knife, looks really nice, performs even better, but the polish is too high for me. I told him we should go satin next time. He laughed and said he was afraid it wasn't mirrory enough. Again, this is proof of these all being up to each person's opinion/preferences.

I'll try to make some mud next time ill sharpen and save it for when i need to polish.

Yes i use lots of water with wet and dry paper.

But as Lefty pointed. i use my knives at work and when it is busy i don't have the time to baby them so they will scratch and patina.
I don't like scratches but i like the patina :D
