Hi all! I was wondering if anyone is from Argentina and knows a good commercial brand for PVA adhesive for leather? So far I've been using the one from Seiwa, but I can't seem to find it anymore in the country. Do you have recommendations? If not, would PVA glue for woodworking do the trick? Thank you!

Hi! So after Philip's review of the 4Z pricking irons I got myself a set, with two sets of prongs: French and olive. I'm kind of in love with my new irons and I was wondering if over time they will need some sharpening (I assume they will). If that's the case, how do you sharpen them? Thanks!
