This is the perfect device for my purposes! I treated the rivet holes with an awl, it was hard work and time consuming to say the least. Since I've had this hole punch, it's become incredibly easy to punch holes in multiple layers of fabric and leather for the bags I make. Reviews saying it was difficult to get the punch material out of the tube must have used some kind of sticky material as the tiny punches fell right through the wheel of this punch for me. It's pretty cool and inexpensive. One thing I notice, pay attention to the position of the brass disc, I've punched a notch in the plastic part of the disc - and without much effort! It is fully functional + it comes with a spare disk!
