Hey bud the one sharpener you're showing in the video is specifically made for small hole punches but a rat-tail or chainsaw file will ruin the punches instantly. I just don't want people to try and blame you for something that you're only trying to help with. That small sharpener is 1 of 2 on the market made to do this job. I just want to help too. Take care.

I set my sinabroks to the side because they needed replaced, I thought. Went back to the diamond chisels, which I never liked the look of. Just happened to run across this video. Man, what a lifesaver this was. I ran down to Harbor Freight and picked up a set of needle files. Now my Sinabroks are like new as well as all my other single hole punches. You have my subscription and my likes.

Those Sinabrok punches 😍. I’m definitely saving up for a set.

Good stuff! Thanks for sharing.

Great video dude! Awesome resource for anyone who uses this kind of “stitching hole maker”!

Awesom!!!! Thank you so much for this video. I was just asking buckleguy about sharpening the sinabroks. I can’t wait to sharpen mine. They need it. I was going to buy more teeth, but now I’m not.

ThankS for this Tim was really helpful!

Cool, I just bought a 3 tooth Sinabrok French stitching chisel.

Thanks, i will try this on my Wuta 4mm🙏

What's are your thoughts on diamond chisels versus punches for stitching leather? Do they have any advantages or disadvantages compared to each other or is this just aesthetic preference?

Tim: Do the individual prongs go into the holder and stop? I am concerned that if I take them out, they will not line up again after I put them back. I do know my own limitations with aligning things. My 1.2mm @ 5mm spacing Sinabroks is my go-to tool punch for .8mm and 1mm Ritza thread. So easy to sew.

I was looking at getting the rotary tool bit to sharpen my punches (still waiting on delivery, wanted to get ahead of the game ;) ) but since I ordered 1mm punches I wasn't able to find a bit less than 1.5 mm. However, I do have bead reamers which do go down to 1mm so I may give those a try.
