Hand saw was invented by Lu Ban, the founder of woodworking. The oldest woodworking hand saw is usually shaped. · By adjusting the tightness of the screws on the opposite side of the saw blade, the saw blade is straighter and easier to work. · After continuous improvement, the hand saw has a long and flexible blade, which is often used for cutting boards and panels, or for splitting cross-cutting wood. The serrations are generally large and used for initial cutting.

The use of hand saw is very wide:

1, woodworking using a hand saw is the most frequent, used to cut wood and other very convenient and labor-saving.

2, garden pruning can also be used hand saw can be used for flowers, seedlings, fruit trees, garden trees and other green plants pruning.

What do you need to pay attention to when buying hand saw?

1, the quality of foreign brands will be relatively better, but in recent years, the quality of the hand saw produced in China is not worse than that of foreign countries, and even many foreign hand saw are made in China, so we can also buy domestic hand saw when we buy.

2, look at the price, the general price of high hand saw is the brand's hand saw price is more expensive, because the brand's hand saw after-sales protection, and the material used is a better material, so we had better buy the brand's hand saw when we buy, even if it is expensive, it is guaranteed after sale. We can't get a refund if we buy three products without a return.

3, see the saw, the finer the saw will form a wider than the saw blade itself. This helps prevent clipping saws. The function of the saw depends on the design of the teeth. The denser the serration, the finer the cut, but the more laborious and time-consuming it is. The direction of the sawtooth determines whether to pull or push the start. When the hand holds the saw, the sawtooth toward itself is the sawing start, and the sawtooth outward is the pushing saw start. Usually do not use rubber strip protection (generally matched), long-term do not need to put on camellia oil protection.

4, see the surface smoothness of the saw blade, the smoother the surface of the hand saw, the better, because if it is not smooth, it will not cut smoothly when buying.

5, hand saw blade material, 304 stainless steel, carbon tool steel, alloy steel, some bad materials will rust, so we must find out what material is the hand saw when we buy the hand saw, do not blindly buy the hand saw.
