Quality superiority. Some domestic military shovels are made of ordinary steel, which cannot meet the special needs of outdoor use well. However, the fine workmanship shovel is made of high-quality imported 420 high carbon steel, which has high strength and hardness, high elastic limit and fatigue limit (especially the fatigue limit at the notch), and the cutting performance is still good. The material is sufficient and carefully selected. Only by choosing the best and the most expensive, and using the best materials in every place, can we get the long-term recognition of customers.
