Selecting the correct material is vital for durability and performance. For heavy-duty construction, prioritize Tempered Steel or Carbon Steel blades (specifically S50C or 65Mn steel) as they offer superior hardness and resistance to bending. For the chemical or food industry, Stainless Steel (304 or 316 grade) is essential to prevent corrosion and ensure hygiene. Regarding handles, Fiberglass is the professional choice for high-intensity work due to its weather resistance and non-conductivity, while Ash Wood provides excellent shock absorption for landscaping.
