Which is more difficult to break than the linear cutting slingshot and the cold bending slingshot?

Generally speaking, as long as it is not the inferior slingshot material such as zinc alloy, it is difficult to pull the slingshot down.

Of course, if it is an extremely hard material, such as casting 440c, the internal stress of the slingshot will change due to quenching.

304, whether forging/cold bending/wire cutting, I have never heard of broken.

In short, metal slingshots are difficult to break if the materials pass the customs.

It seems that all the bows cast are die-cast. Do you still use sand casting technology? Then there will be no sand holes. If there are pores, they can only be pinholes, which are difficult to expose after processing. Even if it is exposed, it can be filled with resin glue under vacuum. It is difficult to find them after polishing, and the wear on rubber bands is almost zero.

Therefore, casting bow is a very good choice. I bought several cast bows and felt the surface quality was very good. The only drawback is that the parting surface at the arch groove is not well handled and it is difficult to polish it by hand. It is still recommended that the bow dealer let the foundry polish it before taking the goods. After all, the processing equipment in the factory is much more accurate than ours.
