I've been waiting to write this review to see how each blade handles different materials. These canvases are great for PVC, wood. I used a wood blade to cut through my 2x4 piece of wood. I used another blade to cut through the PVC piece. So far I haven't had any problems with my blades. I used my saw blades with the following saw: jigsaw, jigsaw Tacklife 6.7 ampere, 3000 rpm with laser guide, variable speed, double bevel cut (0-45°), vacuum tube https://www.amazon.com/gp/ product/B07FCKKY75 /ref=oh_aui_search_detailpage?ie=UTF8&psc=1
