r/sharpening

I messed up trying to cut through some parmigiano reggiano. Bought from Japan a couple of years ago. Can this be fixed? If so, anyone have a good recommendation for SoCal?

In Home Depot getting some spray foam and saw this hanging near the utility knife display. Asking 15 bucks, billed as a 400/1000 splash and go waterstone, mfg in Vietnam. Comes with a hard case. I'm a sucker for the unknown as long as it doesn't cost too much!

Just changed out the water in my bath and stirred up all the stone mud on the bottom of the tub. Its normally not quite so murky!

Didn't mention it in the video, but this 400/1k is so much better than the Sharp Pebble silicon carbide 400/1k, its not remotely close. Anyone wanting to dip their toes into waterstones, this is a pretty painless way to start.

Looking to buy my first set of sharpening stones and a strop. I would like to be able to sharpen my pocket knives and kitchen knives. All I have had previously is a pocket sharpener from work sharp. I was thinking of picking up some cheap knives from good will to practice on some before I start on my knives.

Would this stone combo and strop from sharpal be a good place to start? I think the guides would also help out.

Mounted my new @rutlandstools sharpening jig. Any tips for repeatability of, say 25°, for chisels and plane irons? Three moving parts doesn't help at all!! Works very well though.

Kiwi 21, sharpened on 14 degree and deburred on 17 degree. Does anybody know what is the issue here?

First time posting.

I spent most of my day restoring this Deba. I’m happy with how it came out, and I’ll be making a slightly longer video on my socials in the coming days. Gonna need a new handle for it so I’m gonna outsource that to a friend of mine.

Let me know what you think!

Process

1. Wire wheel on a low speed buffer to remove the flaky rust

2. 220 grit scotchbrite wheel on a high speed buffer to remove more stubborn rust.

3.hand sanding to on 320 grit to remove rust on the ura and face, to also add a slightly rough finish.

4. Primary bevel thinning and polishing work goes as follows: 80 grit belt, 120 grit belt, 120 grit worn belt, 200 grit belt, yoshihiro 400, Naniwa chosera 600, king 800, yoshihiro 1000, Naniwa Green brick 2000, bench buffer with airway wheels.

5. Sharpening progression, Yoshihiro 400 grit (minimal passes, no Ura), king 800 (no Ura), Shapton kuromaku 1000, Naniwa green brick 2000, Naniwa super 5000

After sharpening I then did a final touch up polish with Koyo polishing paste.

My personal thoughts: I could use some more time in the mid stones to make sure all the scratches are gone cause you can still see deeper scratches along the bevel some. I also think it’s from water. I was using mostly the same water up until about 1000 grit and so I assume it’s just all grit contamination at that point. I’m thinking I’ll just to use a spray bottle from now on.

Finally decided to polish my most experimental (read abused) Aogami 2 Hatsukokuro Petty (I liked to call it Ko-Santoko).

Progression was Shapton Kuromaku #320 - Shapton Kuromaku #1000 - Nanina Advanced Super #3000.

I'm changing hands between the sides and for some reason getting nice polish on the left side was really tricky.

I suspect it might be due to the knife being slightly uneven, but I ultimately had to raise the left side slightly to get nice hagane.

Does it look acceptable?

Any recommendations for attempts?

I have a ton of offcuts of ceramic tile at my house from a reflooring we just did and the other day I found a bag of denim pant legs that my daughter cut from her pants to make shorts so I decided to get crafty.

I cut the denim into flat pieces, laid the smooth face of the tile on the back of the denim, traced around the tile and cut it out, leaving about .5cm on each side to wrap around the tile. Then I put contact cement on both the tile and the back of the denim and let it dry a little and then stuck the two together, wrapping that extra denim around the edges of the tile. It's super easy and quick to do.

The diamond lapping paste is from Amazon, I got it years ago and have used maybe ⅓ of the 3.5 micron and very little of the other ones.

I've been using that 3.5 micron paste on basswood lately and I like it better than stropping on leather. I made denim strops a long time ago but the glue kind of puffed up when I made them and they weren't great. I think I used gorilla glue and didn't spread it like I did with the contact cement. I stropped some pocket knives last night with the one in the last picture and it works great. The paste doesn't come off the denim like it does on the basswood which is nice.
