量處輕重儀 1.46

1.46

已上五件，雖所為是輕，而事相繁重，卒難勝負。又道分竦緣，非親機要者，並在重收。就第二件中，微有輕相，如截刀剪刀，佛開畜之，通含大小，可依經判。四寸刃者，無問鐵木角骨之柄，從輕所攝。若依量，已上諸刀，或以金寶飾者，雖量乃寸刃，從寶入重。磨石體量，律論無文。若以刀同恒相隨者入輕。

Although the purpose of the above five items is light, the physical items are cumbersome and heavy, difficult to transport at a moment's notice. Moreover, they are secondary accessories along the path and not intimately necessary; hence they are all classified as heavy property. Within the second category, there is a slightly light aspect: for example, trimming knives and scissors are permitted by the Buddha to be kept, encompassing both large and small sizes, which can be judged according to the scriptures. Those with a four-inch blade, whether with handles of iron, wood, horn, or bone, fall under light property. If they exceed this measure, or if any of the above knives are adorned with gold and jewels, even if the blade is only an inch, they are classified as heavy property on account of the precious materials. Regarding the size of whetstones, there is no text in the Vinayas or treatises. If it constantly accompanies the knife as an accessory, it is classified as light property.
