This symbol is related to Mahadevan's sign number 2065, but whereas the blade body in sign number 2065 curves in a sickle shape, the handle in sign number 1100 is straight.
This makes perfect sense in the light of example M-856, because you would be unlikely to use a sickle to split open a cylinder of tea cakes.
Inscription M-856 also gives us a fascinating insight into the etymology of the Chinese word qiē 切. Xu Shen's definition for qiē 切 was to measure with a knife¹. Hence, it is the verb to segment or to slice. Qiē is a composite character made up of the word knife on the right and the numeral seven on the left, which is precisely what we see in inscription M-856. Thus, the Chinese character may well be derived by reference to splitting a tǒng (a stack of seven cakes, each weighing 546.5 grams, wrapped in bamboo) of pu'er tea into tea cakes.
