you need to do a lot more videos! You’re very good and very thorough. You talk through everything you do explaining why you do it That way and not a different way. I think most of the problems the students have is when there is an air bubble inside the clay. Also when you’re raising something up and you accidentally pressed a little bit more with your right hand, or pressed a bit too hard with your left hand. Also, when you’re trying to raise or you trying to bring some clear up from the bottom, sometimes you left finger is a line with your right finger, but sometimes it slips and that’s the end of what you’re doing! You need to make corrections how do you fix this? How do you fix that? And when you’ve been doing pottery one or two even three years they are tons and tons and tons of mistake you make every week.

I have no idea why you don't have more subscribers. You have been an absolute jem in my understanding of clay and everything that goes with that. Your videos are very clearly explained and you have excellent presentation. Id personally like to thank you very much for the last 10 or so videos I have watched. Thank you

Thank you so much for this video content! It is extremely helpful. Can you explain how to get rid of an area on trim tools when it leaves this one line that looks deeper than the full pull across of trimming, if that makes sense? I have lightly hit my trim tools to sharpen them over time. Somehow, the width of the trim is perfect except for an area that leaves a fine line that’s deeper. Again, unsure if I am explaining this well. Would a company that sharpens knives & scissors have the know how to sharpen pottery trimming tools? I ask bc I’m visually impaired… actually I’m legally blind but I do retain light perception. I just can’t see much beyond a few inches from my eyes & even then, it’s not very well. I have loss of peripheral vision too. I have a retinal disease & optic nerve defect. I’d like to find someone who sharpens knives & salon scissors, etc… it might be a safer alternative for me as long as it’s not overly expensive to sharpen my tools. I’m mostly using files & sandpaper with the occasional hit with the pen/pencil adapter to a Dremel tool. I try to polish using a rouge paste afterward.

Thanks for the video. Just have to nitpick a little. Tempering is not when the metal is plunged into a liquid (water, oil, etc). That is called hardening. After hardening, the metal is very brittle. So it is heated again to a specific temperature that reduces the brittleness. That is tempering.
@JohnHasegawaCeramics
@JohnHasegawaCeramics 2 года назад
Wow that is great to know. I messed up a few times in the video with a few of the things I said. I did not know that tempering.

@@JohnHasegawaCeramics Don't worry about it. I only know about it because my wife is a metal smith. Thanks for your video again, it was very useful for me. I noticed my trimming tools have a bevel but the bevel doesn't extend all the way to the edge, so I'm having to re-profile the edge. Well, you get what you pay for, I guess.

This has nothing to do with sharpening your tools, but they are questions that I’m sure a lot of people have such as how do you throw a vase and make it very thin so you can make some cut outs. There are so many videos I wish you would do and I’m sure that I am not alone. please keep going and also for example when you accidentally pulled a wobble or you are racing in pause or not really reason uniformly so there’s like on the side how do you correct?
@6tamara
@6tamara Год назад
Another thing is that you may want to negotiate with vendors that sell the tools you’re using. And if people are buying their tools and they say it’s with your name that you recommended, they give you a percentage. And maybe they even take two dollars off or a dollar off for whoever’s buying.

Thanks for the video. I was wondering, using your drawing as an example, is grinding the bottom flat plane to bring it up, instead of grinding down the bevel's edge and trying to keep that edge parallel to the original bevel, also a valid way to sharpen your tools? are there disadvantages, such as more difficulty for loop tools?
@JohnHasegawaCeramics
@JohnHasegawaCeramics 3 года назад
Thanks for watching. I do not recommended grinding the flat back side of your tool, it will make the tool much weaker and remove a ton of metal. Only do a little bit of grinding to flatten out the back.

@JohnHasegawaCeramics
@JohnHasegawaCeramics Год назад
The small tools are more difficult to sharpen. they have less metal. I would do the smaller tools by hand and watch carefully to not remove too much metal. Just enough to get them sharp. And then think about getting new ones.

@gbennett58
@gbennett58 3 года назад
Single bevel knives are less durable, not more. Having two bevels on one blade actually increases the cutting angle compared to a single bevel. So if your bevel is 17 degrees on one side, and you bevel both sides, the cutting edge has a 34 degree cutting edge, but a single bevel cut at 17 degrees has a 17 degree cutting edge, so it is a more delicate edge and less durable.
@JohnHasegawaCeramics
@JohnHasegawaCeramics 3 года назад
Yes, I can not argue with your reasoning. I stand corrected.
