𓋴 U+132F4 folded cloth

𓄸 U+13138 folded cloth and intestines

𓋵 U+132F5 folded cloth and horned viper

𓋶 U+132F6 folded cloth and sickle

𓌭 U+1332D folded cloth and knife sharpener

𓌯 U+1332F folded cloth and butcher's knife sharpener

There are other signs that they also combined like this, for example,

𓌌 U+1330C cobra with mace

Both the cobra and the mace are also standalone signs, just as all the signs above are standalone signs in addition to being combined with the folded cloth. Why did the egyptians combine signs like this? I'm not sure. I've never read an explanation for it.
