Thank you for your video, and all the information you managed to fit in. Just starting into leather working, and you managed to help me make a tool selection.
This is good information, I love your channel! I bought half my tools from japan, but all the tutorials I found only mention american side of leather crafting and they don't really explain things as clearly as you do. Glad to finally understand why there's different sizes... Thank you so much for this video! I subbed, going through your videos now.
Thank so much, as I was deciding to upgrade my irons and purchase a high quality set your information has been so so helpful. The best detailed information out there I love your site!!
There also used to be two different metric standards (British and French) and three different standards for the inch standard (the French and British standards were significantly different, and the U.S. vs. U.K. standards varied slightly but measurably). None of these standards is the standard in common use today for manufactured goods. The 25.4 mm to 1 inch, measured at 20 degrees Celsius, was created by Carl Edvard Johansson in 1912 when he started manufacturing gauge blocks in inch sizes. This de facto standard was formally adopted by the International Yard and Pound Agreement as the official standard in 1959.
Thanks alot sir.it is very very very informative video.Thank you so much.i am beginner in leather.please do you have these information in written form? And please make a video about thread also.Thanks alot again.stay blessed. :)
Yes, size of thread matters too and, of course, it depends on personal taste. As a general rule, the wider the space the thicker the thread. If you don't know what thread to start using, go for 0.5-0.6mm. (for example, Serafil has round thread 0.5mm, tiger thread has an 0.6mm option, and it's flat).
Thank goodness most vendors now use x.xx mm instead of xx SPI now. The only thing more unnecessary than my countries imperial units is the paris inch! Simply stating the actual spacing in mm is waaaay more convenient. If it was actually an exact X stitches per an IMPERIAL inch, I could see continuing to call it by the SPI. But this day in age, it does not make sense to me for any other reason than tradition.
Wow, what a mess! Thanks for explaining, but why can't everyone just agree on some normal measurement, not based on archaic and obscure units, and standardize it? The only value that makes any sense to me is the distance between holes, I don't think I'll be learning or using all these tables.
If you’re from smaller county (but also quite old one, which is very important factor.) like me, let’s me tell you it’s a another level of goddam hot mess. Well, we already have our own ancient measurements. Then people just creating a new monster by combined British Imperial with ancient Chinese with our own without any reason whatsoever. One silver lining is younger people hated it too. So we’re moving forward metrics. Just leave…. stubborn oldies with their beloved monster. I learned clothes sewing from my grandma, her old patterns making books have something like “17/32 of an inch” 😅 That’s the reason I’m now exclusively use centimeters.
First I had the cheapo tandy irons, then I switched to KemovanCraft 3mm irons. I would have preferred 3.38 mm. I also want to try French hybrid irons now because I'm too lazy to use an awl lol
My Japanese style pricking irons make sort of a diamond-shaped impression instead of a line. Is that normal? Also I saw on other videos that you can stitch a certain way with the French pricking iron to make both sides of the stitching look almost identical. But I was unable to replicate it with the Japanese style pricking iron. Does anyone know if the identical pattern can be achieved with the Japanese style irons?
