Splitting wedges come in a variety of different shapes and sizes. They’re often made out of durable metal, which makes them ideal for commercial use since they can withstand high amounts of pressure when cutting through logs to split wood! Some models have plastic handles while others have wooden ones instead. The materials used also depend on how you plan on using your wedge – if it will be exposed to rough conditions or extreme weather then opting for something more sturdy is recommended. However, if you just want one around the house as an extra tool that won’t get much wear-and-tear then choosing something less expensive might work better for your needs!
