If you are cutting across the grain, you would use a crosscut saw.

如果你要横切纹理，你会用横割锯。

For example, thanks to those aligned bundles of cellulose fibers, trees are stronger across the grain rather than along it.

例如，由于那些排列整齐的纤维素纤维束，树木在谷物上比沿着谷物更坚韧。

But for those who share my faith, know that I'm about to cut across the grain.

但对于那些与我有相同信仰的人，要知道我即将横穿谷底。
