Cutting Lead Came Angles
How To Make Accurate Straight Cuts & Angles
Cutting lead came for stained glass isn’t as hard as you might think. To make an accurate cut on both sides of the panel you have to cut straight down. This is so that you will have neat lead came angles without any gaps on BOTH sides of your panel.
I’ll show you how to cut lead came accurately before moving on to a 45 degree angle and then one of those long thin angles that everyone tries to avoid!
You’ll find out it’s not so difficult after all.
Tools for Cutting Lead
1. Lead Came Cutting Tools
Shaping lead can be done with a variety of tools. You can use:
Lead Dykes, or Nippers
These are adapted from the side cutters that electricians use. They have a bevel on one side only, which makes them particularly useful for cutting lead.
A Lead Knife
This is the most traditional tool and has been used – in a variety of shapes and sizes – for hundreds of years. The lead knives usually have a rounded blade that helps with the rocking motion that cuts through the lead. They have a weighted end that is used for hammering the nails in. These keep the panel in place as you lead. Keep the blade as sharp as you can for the best results.
Lead Angle Shears
These are fairly new to the stained glass scene. They look and work like a pair of scissors. The cutting blade is a general purpose blade that fits into any utility knife.
They’re normally for those who are making large amounts of lead work. Knives or nippers are quicker unless you’re set up for production work.
If you’re new to using lead came as a technique I would highly recommend you give it a try. It will add a great deal to your skill set and give you the best of both stained glass worlds – foil and lead.
If you don’t have a local class my Leaded Stained Glass Artistry course has taught many people – even those who have never used lead before – how to make a stained glass panel using lead came. The course is self-paced and online so you can learn this lovely technique even if you are unable to get to a class. You can find out more about it here Leaded Stained Glass Artistry.
2. Cutting Lead Cames Accurately
This short video takes you through cutting 3 types of angles; straight, 45 degrees and long thin angles.

The important thing about cutting angles is to be directly above the cut so that you can press down. This is the way to achieve a lovely perpendicular cut.
- The lead knife cuts through the top of the lead came to make this type of cut.
- Start by simultaneously rocking the knife back and forth while you press downwards
- Once you cut through the top flange you can increase the pressure
- Push down through the bottom flange to cut right through the lead came
- Sometimes the top flange squashes a bit. To rescue this, simply use the knife to ease the flange upwards
- Check that the cut is perpendicular
- If it isn’t, you can take a slither off either flange with the lead knife to straighten it out
That’s all there is to cutting lead came straight!
3. Cutting Angles
- These are the angles you need to perfect for those professional mitred corners.
- This technique is essentially the same as cutting straight down.
- Start cutting the top of the lead, rocking the knife back and forth along the angled line
- Push down at the same time
- Once you’re past the top flange you can wiggle the knife from left to right as well as pushing down. This helps you cut the heart of the lead
- When the lead is cut, use the corner of the lead knife to tease the squashed flange back up
- Finally, check that the angle is perpendicular
4. Cutting Lead Accurately
Now for those long thin angles!
- Mark the angle you want to cut on top and bottom flanges of the lead came
- This time you’re cutting the lead came from the SIDE
- Hold the lead firmly with your non-cutting hand
- Introduce the knife to the edge of the lead and start rocking from side to side and pushing forwards at the same time
- Cutting through the heart of the lead came is harder with these angles as there is more of the heart to cut
- Keep checking both sides to make sure that the cut is following the marked line
- When you’ve cut the came, check that the top flange matches the bottom flange.
Sorted! Cutting lead accurately is now one of your skills.
