-Tried hubby's piper cutter, Basically a utility knife blade in a sissor handle that comes down on a cruved cradle for the pipe. Worked great for 45 degree cuts
Is this a PVC pipe cutter?
The one I have would NOT make a very good lead came cutter - blade hardly cuts PVC pipe cleanly, let alone lead came.
I should have said hose cutter.
I believe Sears came out with the cutting pliers first. They consist of an upper blade which moves down to a flat/anvil stop. Many have copied the pliers now. Some like them for lead and many do not.
I think spending time to cut lead for practice is a necessary part of learning. When I taught lead classes, the students continuously cut lead for 3 hours. They were given pictures/drawings of the angles of the cuts. They were to make hundreds of cuts in the three hours. At the end, they understood the process and hated lead, hated the lead knives, hated stained glass, hated the blisters and sore fingers, and hated me. When they began assembling their panels, they knew what to do.
I sure wish I had the opportunity to take your class.

I may go visit Rebecca one day and make her abuse my hands.
