How to use a hand saw
Hand saws have a long history. In ancient Egypt 4000 years ago, hand saws with brass band saw blades and single buttstocks have gradually become popular. Later, Westerners and Greeks invented the frame saw, which could hold the band saw blade more firmly. At the same time, they also discovered the necessity of adjusting the serrated material path. The serrations are alternately separated from the upper and lower sides, so that the total width of the saw seam slightly exceeds the thickness of the woodworking saw blade itself. This type of design prevents the saw jam and has been used to this day.
This type of frame saw was used by woodworkers in the Middle Ages in Europe. It wasn't until the seventeenth century that American hand saw manufacturers created contemporary hand saws with oval hole stocks and steel bandsaw blades. Nearly 100 years ago, there has been an unprecedented trend in special tool design, and kitchen cabinet manufacturers have created tenon saws, which feature a thick wire saw blade and a brass spine with shorter, more detailed serrations. It can be said that up to now, basically all wood laser cutting work can be done with only one saw.
The basic principles of sawing among various hand saws are basically the same, but there may be very big differences between them. Different hand saws have different actual sawing effects due to the number, shape and pitch of teeth. Taking the dovetail tenon saw as an example, its fine pitch can saw a very flat cut cross section, and the raised ridge on its back can ensure that the woodworking saw blade is not easily distorted during sawing. It is a high-precision dovetail. The properties that mortise joints must have. However, for vertical sawing of long products, dovetail saws cannot be eaten. The woodworking saw blades that are commonly used at the moment are longer, have a higher pitch, and have a higher serrated material path.
