What are crescent-shaped blade lead knives used for? |
||||
 |
In came glass work, which is stained glass or leadlight pieces, the lead came needs to be cut without its channels being crushed. The rounded edge of the blade is rocked as it cuts, gradually cutting the came without distorting it. The sharp point can be used to scrap away dried putty or window cement from finished panels. | |||
 |
The crescent-shaped edge is used to shave strips off rigid materials such as uPVC panels and composite doors to get them to fit correctly. Composite doors use a mixture of different materials, layered together, combining the benefits of each material. Materials such as PVC, glass reinforced plastic, wood, and insulating foam are often used. | |||
 |
The thin blade can be used to get into the seams of glass panel beadings in uPVC frames and pry them off. They can also be used to trim weld lines and rods, beading, and seals for uPVC window installation. | |||
