liquify

Hi I've been working with leather for some time but I'd like to improve my works and I decided I'd like to buy some quality tools,like a skiving knife and pricking irons,especially to make wallets.I don't want to spend 150$ on pricking irons,let's say 50$ max. I have one one iron I bought some years ago and its not bad but I can't make perfect straight stitches when I have to punch 3-4 layers of leather,not sure if it depends on me not keeping it perfectly straight or what.This iron has 4 prongs only and I was thinking maybe using a 6 prongs or more would be easier? Can you recommend some good ones?I'm in Italy so not easy to order from US based stores.Thanks for any suggestion!

where do you knot them?between layers?

how do you make that?

thanks for your help.So you suggest to just pull the thread between the layers and cut it without burning it at all?

I'm sure is more simple than I think,but i can't figure out how to make this type of stitch without having to burn the end of the thread on the visible outer part of a watch strap...in this image you can see the thread doesn't appear burned and messed up like the one I get...any help?

me too please
