Depicting sharp INCISORS of a human upper jaw「reciprocating vertical motion with head up and in」used to initially BITE OFF a piece of meat or other foodstuff and CHEW, MASTICATE, grind into smaller pieces, perhaps within a face that is leaning over forward with the head in a horizontal posture as if peering into a fleshpot to select a morsel. Extended meaning of a MATTOCK is an implement with the same shape as incisors that is used to BITE AND SEIZE soil, effectively "chewing" it into smaller chunks prior to implanting.
The first time through a hymen can have a bit of a bite or sting, it has been reported, while leaving that membrane looking a bit CHEWED UP. And with a sack of rocks attached, the client's "tool" used for pounding the meat of a young and small Chinese service provider, including her no-longer-integrated feet with repeated banging after the metatarsal bones had previously been pulverized with another harder tool, such as a large rock, or even by using a MATTOCK (by the more rural do-it-yerselfer folk in dynastic China).
　Be sure to see 乍 meaning「adze」a specialized type of mattock, meaning「to break in, first use, both, to stand one's hairs on end.」
　A MATTOCK that is a type of early tool for BITING into formerly untilled soil and breaking it into large chunks, usually a flat rock sharpened somewhat as a blade and fastened to a stout tree branch at about a right angle, resembling the incisors (that make 'incisions') of a human upper jaw and used while leaning over forward with the head in a horizontal posture.
　The blunt end of a mattock head was also used to depict the dis-integrating and mashing of the foot bones of a young girl, a procedure performed at home by cost-conscious, dirt-poor serfs looking to bypass the middleman shaman when selling a daughter into sexual slavery and thereby maximize profit, using 'cunning metal for making musky-smelling bunny coneys' (related glyph, 鑱). Unfortunately, when an inexperienced non-professional performed this procedure using crude implements, the results more often than not were a CHEWED UP mangled bloody chunk of meat that appeared to have been MASTICATED rather than something that healed later to become smooth symmetrical erotic flesh pouches.
　「The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet」(after unbinding the cloths, of course)

　RAISED FEET AND LEGS while in a sitting position, perhaps a reflexive motion after being BITTEN BY INCISORS while in a sitting position, or, raised in order to put on one's trousers (see 啗 and 歯). RAISED FEET AND LEGS while in a sitting position also clearly describes how those pulverized feet were put to use by horny males, as depicted over and over again in Chinese erotic art.
　In modern fonts this element is often used in the left position to represent the lower stroke of「person sitting」(due to no-longer-integrated feet 匕 )
　Katakana「re, le」is used here as a substitute, as this element does not seem to exist as a separate glyph. Japanese sources at times count this element as a single stroke, and at other times as two strokes (not surprisingly,「rod」with「head up and in」), a situation that contributes to using the total stroke count for a glyph only as an approximation…if you cannot locate a glyph that uses this element, try expanding your search within the counts one higher and lower.
