When choosing solid wood ripping and cross cutting saw blades,the following aspects can be taken into consideration:

For ripping saw blade:

teeth shape selection : The left and right teeth are usually used.This kind of tooth shape is relatively sharp when cutting,enabling the saw blade to cut wood more smoothly and quickly when cutting wood for ripping. 

tooth number requirement: a smaller number of teeth is more suitable.It is mainly convenient for chip removal and not easy to get blocked.It ensures the continous progress of cutting work.Moreover,the cutting speed is fast and the cutting work can be completed more quickly.

For cross cutting saw blade:

teeth shape selection: Flat-triple chip tooth are generally recommended.when flat-triple chip tooth saw blade cross cutting wood,it can reduce cutting resistance and avoid edge chipping of wood ,and it performs well when cutting hard wood.

tooth number requirement: it compared with ripping saw blades，the number of teeth on the crosscut saw blade can be appropriately more.Frist of all,this is because crosscutting mainly cuts the wood fibers,and more teeth can reduce the amount of cutting per tooth,which can make the cutting process more smoother,reduce the tearing and edge collapse of the wood caused by the large cutting force, and help to obtain a smoother cut surface.Secondly, more teeth can increase the number of cutting edges involved in cutting at the same time, which can effectively disperse the cutting force, reduce the load borne by a single tooth, and thus improve the durability of the saw blade.

In addition, the diameter of the saw blade should be selected according to the size of the cutting wood and the sawing machine used. The material of the saw blade should also be considered. For example, carbide saw blades are more wear-resistant and have a long service life, making them suitable for large-scale solid wood cutting work.
