In addition to the glass cutter, the putty knife is an essential tool for glaziers and window fitters. Used for applying putty when fixing a window pane to a frame (whether PVC, iron, aluminum, or wood), this tool is also useful for smoothing or removing this material. Indeed, the putty knife is the ideal tool for calmly replacing or installing a windowpane or mirror.
Specially designed for glazing and mirror work, putty knives are particularly useful for applying and smoothing putty at the bottom of the rebate to replace a tile, pane, or glass. You simply need to smooth the putty with the knife at an angle of about 45°, then slide it along, applying fairly strong pressure. Putty knives, such as those from the Franpin-Nespoli brand, also allow for the installation and replacement of classic single-pane, double-glazed, and old glazing on frames of various materials. To effectively remove putty from the rebate, it is advisable to carefully tap the knife with a glass hammer. The hard wooden handle of the knife provides better rigidity as well as good resistance. Among the many types of handles for knives, whether curved or straight, there are also indestructible plastic handles and beechwood handles that are drilled for hanging.
